Obstacle sensor, based on TCRT5000, uses infrared diode and photo-receiver to detect obstacle in front of it - emitted light just reflects back to the sensor. Onboard, you'll find voltage comparator, ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

I live in Belgium and the water meter I have is a Sensus 520 which has a small spinning wheel with a metal plate. The solution to read it was by using either a reflective sensor or a proximity sensor.

The sensor operates at 5V for Arduino and 3.3V for Raspberry Pi, ensuring seamless integration with these popular microcontroller and microcomputer platforms.

Garbage has always been a problem in Indonesia. One root is the lack interest in throwing them in their proper place. Additionally, the waste that has been disposed is not managed properly. In ...

Proximity Sensor Switch – Circuit Diagram The circuit diagram of the wireless load control unit is shown in Fig. 2. This design is based on Arduino Nano board and built around an I2C LCD (module1). It ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...
