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) ...

Abstract: Pyroelectric infrared sensors (PIR) are excellent devices to detect human/animal presence with a small form factor and rugged design, for cost-effective surveillance. They are widely used to ...

The library gives control over up to 16 parallel working PIR devices over I2C. The idea for this library came up in a discussion about how to fully cover an area with PIR sensors without blind spots ...

When it comes to modern electronics, the word “smart” seems to apply to almost every kind of device on the market, especially building automation products such as motion sensors and consumer products ...

Photoelectric sensors are one of the most vital components when it comes to industrial automation that enables high speed, accuracy and reliability. These sensors include both active and passive types ...

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 ...

Posts from this topic will be added to your daily email digest and your homepage feed. The long-promised Thread sensor is finally here, but while there are some improvements, Matter’s shortcomings ...

Smart homes are becoming more and more intelligent by the day, but there’s nothing quite as smart as a home that can detect where you are in order to automatically trigger a wide variety of different ...

The gunshot-detection system ShotSpotter has for years drawn criticism from activists and academics who believe the company behind the system, SoundThinking, places its microphone sensors primarily in ...

Living objects with a body temperature above 0°C emit heat as infrared radiation, also known as thermal radiation, which is invisible to the human eye. PIR sensors, designed for this purpose, can ...
