Today we are making a simple project with Arduino which uses three basic components that are IR Sensor, Relay Module and DC Motor. Here we will interface IR sensor with Arduino to control DC Motor.

An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect ... projects with ...

Fig. 1 shows the PIR motion sensor module. It is usually hidden behind a translucent dome shaped cover as shown in the inset in Fig. 1. Circuit diagram of the IR motion sensor relay switch is shown in ...

4: Module with IR sensor pair and LM358 Pin diagram of the relay ... Hence, current flows through the motor. Fig. 5: Pin diagram of the relay When the right side of robot is on the white surface, the ...

So, you can easily make this home automation project at home just by using an ESP32 and relay module. Or you can also ... components as per the circuit diagram. Then connect the ESP32 board, DHT11 ...

If you don't want to use PCB, you can also make this IoT project using an 8-channel relay module, ESP32, and IR receiver sensor. This is the complete circuit diagram for this home automation project.
