Wiring these sensors for Arduino use is really easy. First up you’ll need to power the transmitter. Connect the black wire to ground and the red wire directly to 3.3V or 5V power. It will draw 9mA from 3.3V (lower power) and 20mA from 5V (better range) Next up you’ll want to connect up the receiver.

IR Communication basics. IR communication is basically done by two components, an IR transmitter which is a IR light placed in the remotes and a IR receiver which is IR sensor placed at the receiving end like in T.V’s, cars or anything which has to be controlled by the remote.
Nov 20, 2018 · An IR Sensor is a device which can detect the presence of an object in front of it. We have used two blade rotor (fan) and placed the IR sensor near it in such a way that every time the blades rotate the IR sensor detects it. We then use the help of timers and Interrupts in Arduino to calculate the time taken for one complete rotation of the motor.
