In this Arduino IR sensor module tutorial we are explaining how to connect IR sensor module with Arduino Uno and write the code to get the IR motion sensor working.

The IR photodiode receives these reflected IR rays and hence, the resistance and output voltages vary accordingly. Using this variation of output voltage (or resistance of photodiode) we can build the ...

This circuit uses invisible infrared light to detect the movement of people through the door. A short beep will be generated when the infrared beam breaks. So it is ideal to monitor the passages in ...

IR Sensor Operation: The IR sensor emits infrared light from an LED and detects the reflected light with a photodiode. When an object comes within the sensor's range, the amount of reflected light ...

About This is a small script to test if an IR led, IR photodiode, an arduino and a 3D printed nose poke device work properly.
