It’s pretty easy to take a balloon, fill it up with helium, and send it up in to the upper atmosphere. It’s much harder to keep track of it and recover it when it falls back to Earth. If you’re trying ...

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: Compact integrated thermal sensors are utilized to measure hot / cold spots in CPU cores in multiple locations and are important for the power/performance of the chip. Bipolar junction ...

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 ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

Rutronik Adapter Board RAB7 is an open-source hardware Arduino shield designed for AI-powered Sensor Fusion with seven environmental and inertial sensors from Bosch, Infineon, and Sensirion. The ...

This is a library for the Arduino IDE that helps interface with ST's VL53L4CD time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

The Sharp GP2AP03VT00F Time-Of-Flight sensor seems to be a nice part for makers and roboticists, focusing on good short distance sensing where other parts sometimes have problems. Alas, Sharp seems to ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...
