And non inverting end pin 3 is connected to the junction of photodiode and a resistor. An infrared sensor emits and or detects infrared radiation to sense its surroundings. We will connect the infrared transmitter in series with a 220 ω resistor as follows.
The working of any infrared sensor is governed by three laws.
And non inverting end pin 3 is connected to the junction of photodiode and a resistor. Ir detector circuit this circuit is very simple. The working of any infrared sensor is governed by three laws. Pir sensor only detect the presence of the infrared rays which comes into its range it does not emit infrared.
