While there are loads of impressive and complex projects here on Hackaday, sometimes it’s the simple ones that really speak to us. In this case we were presented with [Isabell Park]’s easy-to-follow ...

Unlocking deeper control and reliability with ESPHome projects that turn everyday sensors into powerful smart home upgrades.

SwitchBot has announced a new product called the Presence Sensor with mmWave Radar. This sensor is built to detect people in ...

Thieves beware. If you prowl around [Matthew Gaber]’s place, you get soaked by his motion activated super-squirter. Even if he’s not at home, he can aim and fire it remotely using an iPhone app. And ...

Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

SwitchBot has unveiled its latest gadget, a battery-powered presence sensor that promises far more accuracy than your typical ...

The LS6506R is a pyroelectric infrared (PIR) sensor interface IC that is designed to drive a latching relay. However, the device can be used in a wall-switch configuration (no Neutral available) to ...

In this YouTube video, the team from Mythbusters try to beat a thermal intrusion security sensor (a passive infrared sensor, aka PIR, that detects thermal differences). See how many attempts and what ...

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 ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR ...

Motion sensing is the detection of the change in position of an object relative to its surroundings or vice versa. There are many kinds of motion detector methods: infrared, optics, radio frequency, ...
