In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

A compensated Pt100 RTD circuit has 1 mV/°C DMM output, with linearization via positive feedback, pending Part 2 ...

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 ...

The P0118 code means that the engine control module (ECM) has detected a voltage signal that’s too high from the engine coolant temperature (ECT) sensor (below). In practical terms, the ECM believes ...

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display ...

Arduino is being acquired by Qualcomm subject to regulatory approval for an undisclosed sum. Qualcomm Arduino introduces a new UNO form factor board, the Arduino UNO Q, which features both a STM32 MCU ...

A robust, production-ready DHT22/AM2302 sensor driver for the WCH CH32V003 RISC-V microcontroller using TIM1 PWM Input capture mode for precise pulse width measurement. Code examples are available in ...

Steve Moser has posted on X about some code he found in the Home app of the iOS 26 beta. The code describes an “Adaptive Temperature” feature for home thermostats, which appears to offer several ...

It's a little fussy to set up, but gives real insights into how your body is responding to hot weather exercise. Beth Skwarecki is Lifehacker’s Senior Health Editor, and holds certifications as a ...

If you're into robotics or electronics, you've likely come across Arduino—a small microcontroller that can control sensors and motors for nifty DIY projects. Like the Raspberry Pi, the Arduino is ...
