Aug 15, 2021· Pin 1 is the output so we wire this to a visible LED and resistor. Pin 2 is ground. Pin 3 is VCC, connect to 35V. When the detector sees IR signal, it will pull the output low, turning on the LED since the LED is red its much easier for us to see than IR! We will use 4xAA batteries (I use NiMH) so that the voltage powering the sensor is ...
