Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

Implements a receiver for signals from an NC-3982-675 weather station sensor using an Arduino Nano and an inexpensive 433 Mhz receiver (RX470-4) from AliExpress. Allows for connecting and reading from ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

The Arduino Uno Infrared Sensor Receiver Module detects infrared (IR) signals emitted by IR transmitters. It typically includes an IR receiver and a circuit to demodulate the received signals, ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Abstract: We connected $\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...
