    Very good video, with lots of info & well delivered.
    I wonder how this channel flew under my radar (pun intended) for so long.
    Subscribed! 👍🏻
    Now, I have a couple of things I'd like to point out if I may.
    8:07 The circular thingy serves as a capacitor for the oscillator (high-frequency NPN transistor), not an antenna.
    The antenna is at the other side, & it's a common transmit/receive antenna.
    10:44 Although the LED pins are correct (anode = longer), the internal electrodes are wrong (anode = smaller, not bigger).
    I'm pointing this out because I believe one should look at the internal electrodes to figure out polarity, instead of the external ones, since the latter can be cut.
    & if people learn it wrong from this video, they may run into problems in the future.
    20:02 I'd pull the button Pin to LOW, instead of HIGH, for two reasons.
    - If you pull it HIGH, you're constantly sinking 0.5mA, regardless of the button's state.
    Yes, that current is negligible in this circuit, but I believe it's important to adopt "good habits" anyway.
    In the case of microcontrollers, taking their limited power capabilities into consideration is one of them.
    - It feels more intuitive to "send a signal" to the Pin when the button is pressed, instead of "disrupting a signal".
    I believe it's easier for less experienced tinkerers to understand too.
    From what I've read (I haven't tried them myself, yet), those sensors don't interfere with other GHz devices (routers etc).
    Apparently they don't interfere with each other either!
    So using BT shields should work well too.

    Just watched your tutorial and set up a new rcwl-0516 as I watched. I bought 20 and the 1st one I tested works very well. It's set up in front of the TV pointing back at me and it is very responsive and stable behavior too. Great channel and tutorial. Thanks!

    • @jacobdavis000

  • @TonySwitzerland
    @TonySwitzerland 4 роки тому +1

    Perfectly explained! Thank you.
    I connected the sensor without Arduino to a "remote doorbell button". Battery operated, small size, can be placed wherever it suits. The bell then rings (or just the LED flashes) when someone enters the controlled zone. Works through walls and doors!

    @ShedOfDreams 5 років тому +1

    So useful I bought some! Thank you. A good, concise video. I attached the output signal to an optocoupler relay module and the relay switches, so that's good! I've also found that if you keep moving around, the sensor is always active so the relay stays on E.G. running a light bulb, alarm etc. turns off once movement stops. would be good for a self contained alarm/light/ device on its own without needing an Arduino (or Picaxe in my case) so saving a few quid!!!! thank you again, You"ve got a new subscriber :-)

    I think it's more appropriate to call this a motion sensor, or motion detection module. It has no capability to detect 'proximity'. Any stationary object in the sensors proximity will not be detectable nor can it determine the distance to an object's proximity.

    Excellent video! The speed of instruction is perfect for the average mind and the illustrations are precise and well-synced with the language. But why the dropping resistor? I built the circuit on a breadboard using a 3.3v LED to match the 3.3v level of the output pin. Also, LEDs come in varying voltage ratings; 3.3v being just one. I also want to try replacing the LED with a piezoelectric element to see if the output pin has enough grunt to drive it.

    Excellent! Waiting for my sensors to arrive. Practical discussion of using PIR or ultrasound vs this radar sensor (range, false positives, penetration of glass windows, etc) will be addressed in my own experiments. It would be nice if the sensor did not stay on for two seconds so it could be rotated and data collected in many directions in real time. Thanks for your great projects, well explained, as always.

    • @ristomatti

    Hi all!
    Thank you Bill for that video.
    I have a problem with my chickens. They always come to my patio and make it dirty. My project is to create a forbidden zone. So, I experimenting with a system to chase them away. I plan to use the product shown in this video to pilot two perpendicular air jets. These streams should be oriented on each side like a barrier and start simultaneously when a bird approches. To synchronize the actions, I wonder if that way of proceeding is a relevant choice in terms of sensitivity and speed. If someone has an idea or an experience, I'm interested.
    I look forward to reading you.
    Thank you very much.

  • @tonytee981

    Hi,
    First I have to say that I really enjoy your instructional videos. You are one smart cookie. Keep em coming :)
    Secondly, I purchased the RCWL-0156 sensor and wired it up, both on its own, and then to an UNO, as per your instructions. ( I have a fair bit of experience with Arduino, and everything related to it, so I am confident that I connected everything properly) . I used a 220 ohm resistor for the out pin to the led. My issue is that although the RCWL functions properly. (IE: The led lights up when the sensor senses movement), it only has a range of 2cm. It doesn't pick up anything further than that. I received 5 units in my order, and tested all of them, and they all have the same range (2cm).
    Has anybody else experienced the same issue. Any ideas as to what could be wrong.
    PS: I tested with 2 different power supplies, first the UNO, and then I hooked up my Korad KA3005D set first to 12 volts, then to 24 volts and 0.003 amps. The sensing range was the same for all tests.
    Could it be a bad batch of sensors ?
    Cheers,
    T

    Another side benefit of this circuit with remote is the microwaves knock out car key remotes , so if your car key is cloned no one can use it anyway cause the only way to open car is with key manually while the detector is running when you come back turn off microwave and you can open car again

    Why the comment about the safe use of microwaves when using this board? I don't understand. Aren't microwaves all over the place already? Nobody mentions safety when working with IR emitting devices. IR radiation is of both higher energy and absorbance by the body.

  • @vinny142
    @vinny142 3 роки тому

    Tiny nit to pick; The dopper effect was not *discovered* by Doppler, Doppler was the best known source for a detailed description of the ffect. A bit like how Tesla is credited for inventing wireless power transmission even though induction and radio had been wel documented long before Tesla's grandparents where born.

  • @mrsalts5336
    @mrsalts5336 4 роки тому

    When you explain the Doppler effect, you show the base frequency as 1000Hz and then 2000hz when object is approaching. Think about that for a moment, that can only be true when the frequency is doubled, or when the emitter is moving the same speed as the wave. Either Mach1 for sound or Warp1 for radio waves. But, how do you make sure the emitter isn't arriving at the observer Before the wave?
    Typically, Doppler doesn't operate on such extreme multiples or fractions of the base frequency that you presented.

  • @salukikev
    @salukikev 3 роки тому

    I just discovered this sensor last week, its very neat! I'm surprised its taken me this long to realize it exists as it seems to be a fantastic replacement to a conventional PIR sensor, and equal or better costwise as well. In fact now I'm wondering why anyone would use PIR when this is available. Can you (or anyone) breakdown any pros/cons between the two? So far it seems like a no brainer to go with this instead.

    • @rupeshkoulge1616
      @rupeshkoulge1616 2 роки тому

      One corn i observed was this sensor is sensitive for motions beyond the walls or even doors so its not good if you are placing this on a wall to monitor motion within a particular room.

  • @henrikjensen3278
    @henrikjensen3278 5 років тому

    I like seeing different modules tested and used, it is a good way to get ideas.
    Why do you believe it uses doubler effect? My guess is that it works the same way as ultrasonic movement sensors (Not distance measurement) and PIR detectors. That is you get some "DC" level depending on the environment, if anything moves in the environment this level will change. The chip will amplify these changes and if they are above a threshold trigger the output.
    Another detail is your switch connection, why use a resistor? A single line in the program will make the resistor obsolete.

    • @dirkj9029
      @dirkj9029 5 років тому

      A comparison and more detailed explanation can be found in a video by Andreas Spiess at ua-cam.com/video/9WiJJgIi3W0/v-deo.html What you are referring to by "DC" level is the (processed) output of a sensor device. Radar, ultrasound and pir sensors each use a different physical phenomenon to obtain a measurement.
      Regarding the resistor: the internal pull-up resistor inside the MCU(which is what you are referring to) is rather large and can vary between a relatively large range. It will be sufficient in most circumstances. However, if you have bad luck and have a MCU batch where the pullup's are rather big, the pull-up effect can be too weak in a noisy environment and cause false triggers. Therefore it is good practice to use an external and known resistor. That way, you can create more robust hardware and decrease its value for noisy environments. Often this is also combined with a small capacitor (e.g. 100nF) to suppress/filter any picked up high frequency noise.

    Good video. I attempted to use one of these RCWL-0516 sensors with an ESP32 (client) configured to send the motion detected via ESP-NOW to another ESP32 (server). Unfortunately I’ve come across a small problem. The Wi-Fi function of the ESP32 causes false triggering of the RCWL-0516 if it is in close proximity to the ESP32. I don’t thinking it is the sending of the ESP-NOW messages causing the problem but when the ESP32 module comes out of deep sleep and the Wi-Fi initialises.

  • @home_Grown_studio

    I have been making attempts with a great deal of failure due to PIR sensors instability . These PIR sensors seem to have a mind of their own going high for no reason. They all do the same even at minimal sensitivity settings. My Build design consists of one Servo motor to provide Panning .. Also four PIR sensors facing North, East, West and south. as each sensor goes HIGH the servo turns in the direction of that PIR sensor.. The sensors have side blinders to prevent false directional readings. I hope that the RCWL-0516 Microwave Proximity Sensor may help

    Hi, Bill thank you for another in depth video with excellent details, I know you were unsure about the esp8266-01 due to signal crossover with Wi-Fi.

    Seems like a great device to detect Orchestral Manoeuvres In The Dark.

    Thank you for the video. One question … the first ones I do bought, only worked in 1 cm around, so I do bought another ones. The new ones worked well. I realised that the new ones have an 7133-1 regulator. What are the differences between ones with this regulator and the ones without it? Again thank you for your videos, they are very instructive 😃.

    Thanks for an informative video - question I have is - how directional is the radar on the RCWL0516? Can one make it only detect in a narrow range as I am thinking of using it on a model railway layout and to trigger only when a train passes by ? - thanks
