How to distinguish from a mixture of IR's, whether it is LOW active or HIGH or active sensor? Thanks in advance.

[@crazytronics9917]

You have to check it individually

[@jamesallen6007]

Thanks for this. Please can you tell me why when I go towards the sensor it switches off, and when I move away it switches on. Is there a way of reversing this. Thanks

[@crazytronics9917]

It will be active low IR sensor

can we measure distance with this type of sensor

[@crazytronics9917]

No it’s only detects objects can’t measure the distance

Sir my second led IR sensor module is not glowing.
When I put my hand in front of the IR sensor it is not showing any indication.

Try with rotating potentiometer

How to know whether is it active high or active low sensor, when it is look like same?

[@crazytronics9917]

Check it individually

@@crazytronics9917 if I need active high, then what should i do if shopkeeper give active low?

[@crazytronics9917]

@@mkbiswas2000 no need to buy new IR sensor
Just change your program ,
In your program where you have write conditional statement for IR sensor Replace High to Low in there

wrong information - IR sensor is not used for motion detection.

[@po-gchannel6247]

It can if you want. Depend on your code

[@prakashdurge9357]

Realy kase lagana

[@crazytronics9917]

you have to build an additional circuit for that or you can also connect relay with arduino

[@slowgammerchanel9203]

5cm re jyada hai

[@crazytronics9917]

It's sufficient

[@jimedgar6789]

Evryone asking about ACTIVE LOW or ACTIVE HIGH. It depends on which crappy version you bought. These are terrible components and very unreliable for more than the 5cm that is mentioned here. However it is easy to tell which you have. Simply power up the device with 3v3 to 5v0 and measure the OUT pin as you are bringing some very bright object into range. As he says, BLACK object is not good. I use a reflective metal like aluminium. Obviously, if you are measuring HIGH when your object is within range, then your code will need to accept that as "object in range" otherwise LOW will determine an "object in range." These are cheap and really do not work as they are advertised. They say 5cm to 70cm. I laugh. I can not get these to work barely beyond 5cm. But for certain applications they are perfect for the price. Good luck my friends !
