IR sensor work on the principal in which IR LED emits IR radiation and Photodiode sense that IR radiation. Photodiode resistance changes according to the amount of IR radiation falling on it, hence ...

This project is a simple IR Sensor Module Circuit Design that detects nearby objects using infrared reflection. The circuit is ideal for beginners in electronics or embedded systems and can be used in ...

Circuit Diagram and Explanation. We have used op-amp LM358 in this circuit, LM358 has two voltage comparators inside it, and we have used one comparator here. Non-inverting end (PIN3) of voltage ...

Fig. 3: Circuit diagram of line follower robot using LM358 Sensor. Two pairs of IR transmitter (IR TX) and IR receiver (IR RX) sensors are used. When a surface is detected by IR LED, IR rays emitted ...
