I will use the ESP32 with an RTC and an SD card to datalogger the sensors.

      The Arduino IDE is a free download
      programming in in C++
      ESP32 is commonly available from on-line suppliers.
      BME280 (not BMP280) is available from same supplies
      You can cut and paste to get this to work.
      I would say there are a lot of steps, but Rui has on all the hard work and
      given a step-by-step tutorial for you to follow.
      but, you have to follow from the very beginning to add the ESP32 to the IDE

      this is specific to the ESP32 or to the ESP8266. the ESP32 has more I/O pins and a few other benefits.
      the steps are explained.
      you have to get the Arduino IDE, free from the Arduino Website
      take some steps to load the specific chip (32 or 8266 one and then the other)
      down load libraries
      download the program
      assemble the board with the BME280 (I think pull up resistors might be needed, more data on the web)
      he goes pretty fast on this video, but the tutorial is step-by-step with links.
      since FlowCode has a C++ as part of the options, you should be able to port this into FlowCode, then add what you need.
      if you wanted to port this from C++ to a PIC, then I would hope FlowCode can do the heavy work for you.

      It was just an arbitrary number that I decided... I found it was a good amount of values to see either in a mobile or laptop browser. You can modify the HTML page to let you see hundreds of points per chart. Just open my index.html file. Then, search for "40" and modify those values to 100, 500 or any limit that you want

    • @dave-in-nj9393
      @dave-in-nj9393 5 років тому +2

      as you try to display more, the points run together and become almost un-readable.
      I think the next version should have a button on your Android that says 40 200 and 1000
      that would be a day and a half, one week and one month if you take readings every hour.
      that way, you could press the value on your phone, and the chart would fill to that.
      I think it would be great to have a way to see the last 200/1000 stored readings and not have to wait for it it fill

      You can adjust the different polling rates for each sensor in the HTML file.

    Goodnight friend.
    Gonzalo Rojas from Venezuela writes to you.
    I am working with the ESP32CAM development card, specifically with the example of CameraWebServer, it compiles and records well on the card but when I click MonitorSerie it generates the IP of my WiFi, however it does not connect with that IP on the internet, also on The Serial Monitor generates the error: E (321) esp_core_dump_flashz ɕ dump partition found!
    E (321) esp_core_dump_flash: No core dump partition found!
    COULD YOU HELP ME WITH YOUR ENOUGH EXPERIENCE?

    Hey man, thanks for the tutorial. I've followed it step by step but when I go to upload the code, in the serial monitor it reports that no sensor is found, check wiring. I checked the wiring and its exactly how you have it. Im using an esp8266 with the same bme280 sensor as you. I've used an IC2 scanner and it can't discover the sensor. Any ideas whats wrong?

      Try this. 1000* 60* 60*3 is 3 hours in miliseconds. That function displays the time in milliseconds since 1970. In the code you specified the time format, that's why the normal time is displayed, in hours, minutes and seconds . So, for GMT -3, you just have to subtract the 3 hours, exactly as I showed you.For GMT plus, you do the opposite, that is, you add up those hours
