Lm358 Ir Sensor Circuit Diagram. In this video i have made an ir infrared sensor module using lm358 on a breadboard. Photo diode is connected in reverse bias inverting end of lm358 pin 2 is connected to the variable resistor to adjust the sensitivity of the sensor.
We are using it as a comparator r1 100k ω potentiometer variable resistor. I have also shared the ir sensor circuit diagram link in the description. The ir transmitter in this circuit is an ir led and the detector will be a photodiode.
We will show you how to design a circuit that can sense the heartbeat by using an lm358 ic along with an infrared transmitter and receiver.
We will show you how to design a circuit that can sense the heartbeat by using an lm358 ic along with an infrared transmitter and receiver. Infrared sensor circuit with infrared transmitting tube d1 and infrared receiving tube d2 as the core. Here in this infrared sensor the lm358 ic is used as a comparator for comparing the sensor and reference voltage. So when an object comes to the ir sensor the amount of ir rays from the ir transmitter falls on the ir receiver increases and therefore the voltage at the resistor increases.
