This project is a motion light sensor using the Arduino Nano BLE sense board. This project takes advantage of Cyberon's voice recognition framework to turn an LED on and off via voice commands and not ...

PIR Sensor Module Parts. The topmost part of the PIR sensor consists of a lens with concentric grooves carved into the plastic. These are called Fresnel lens.. The contours on this plastic helps in ...

Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

When the sensor detects motion — i.e. someone passing in the hallway or someone opening the door — it turns on the two lights only if there isn’t enough ambient light to begin with.

The new Eve Motion costs $39.95, which is $10 less than the previous version and its closest competitor, the Philips Hue Motion Sensor (which uses Zigbee and also monitors temperature).
