Here is a simple optoreflective sensor circuit based on TCRT5000 module. It is ideal for projects like robotics, position sensing, proximity sensing, detection of reflective materials and many more.

The circuit diagram of the infrared sensor based power saver is shown in Fig. 2. It is built around bridge rectifier DB107 (BR1), PIR motion sensor connected across connector CON2, timer NE555 (IC1), ...

Connect the IR sensor module to the Arduino board as per the wiring diagram provided. Connect the four-channel relay module to the Arduino board following the wiring diagram.

We'll show you the exact wiring connections, provide working arduino soil moisture sensor code, and guide you through common troubleshooting scenarios that every maker encounters. In this article, we ...

In this project, we selected a proper IR receiving component and designed the circuit in a way to act as stable as possible. Also, you can adjust the sensitivity of the sensor to detect the obstacles ...

• Sensors (IR Sensor): We have used IR Sensor Module as the line detecting sensor for the project. It consists of an IR LED and a Photo diode and some other components like comparator, LED etc. As ...
