Aqara is introducing a new presence sensor that is a natural addition for HomeKit users who want reliable automations without the need for a camera. The new Aqara FP300 combines mmWave presence ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Abstract: In this paper we present a way to reduce the standby power consumption of a PIR-sensor-based lighting device. Generally, although a PIR-sensor-based lighting device will turn on when motion ...

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 PIR library implements a class to monitor 1 or more PIR sensors. The library supports default 8 PIR sensors per object, which typically are added in setup(). It is possible to add a sensor (pin) ...

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.

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 ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...

Yes, you can program Arduino with Python using the PyFirmata library. While Arduino traditionally uses C++ code, Python can control Arduino boards through the Firmata protocol, allowing you to ...

The FP1E’s millimeter wave technology provides for a much more nuanced look at whether a room is occupied or not, but you’ll need one of Aqara’s Zigbee or Matter smart home hubs to use it. Whatever ...
