In this video I'm walking you through the steps I took to make a standalone version of my pellet level monitoring sensor that is not directly connected to Home Assistant but it functions separately .

Last year, Qualcomm acquired Arduino, a company known for its tinker-friendly microcontroller kits and single board computers (SBC). The first product to follow was the Uno Q, which was powerful ...

This water level and temperature monitoring system uses contact or non-contact water level sensors along with a probe-type temperature sensor. A digital display provides continuous, real-time ...

I’ve just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m range, ±5mm accuracy, and Modbus communication over UART. The 0.15m to 40m ...

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 ...

The durable Arduino Opta micro PLC enables industrial and building automation. It integrates with existing machines, devices, and the modular Arduino ecosystem – from sensor modules to SOMs and ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

The working principle of the water level sensor module is very similar to that of a Rain Sensor. The water level sensor has three pins, runs on 5V power, and gives out the data in analog format. The ...
