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) ...

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 ...

Walking safely and confidently can be a challenging task for visually impaired individuals, but with the help of technology, we can make it easier for them. This DIY Blind Stick is an innovative yet ...

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 ...

Trumpeted as the world's smallest pyroelectric infrared (PIR) sensor, the IRS-B210ST01-RI measures 5 mm x 4.7 mm x 2.4 mm. The component is also said to be the only surface-mount PIR sensor available ...
