PIR（Passive Infrared Detection）are used to detect motion of human movement. This version has a large lens which can support long range and wide angle. 2.54mm standard connector is easy to fix it ...

Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

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 gathering parallel light ...

Automated test stations don’t always need proprietary test tools. Using a microcontroller, a PC, and free software tools, we developed an automated test station to test and align motion sensors. Test ...

This RCWL-0516 module has the characteristics of high sensitivity, high induction distance, high reliability, large induction angle, wide power supply voltage range, etc. it is widely used in various ...

A modified Filament Motion Sensor module for Klipper 3D Printers. The vanilla module provides little to no information to help you set the best detection length so I updated it with status keeping and ...

Abstract: This paper presents a development of a 3D motion sensor IC which detects inertial movements and earth's magnetic fields for a compass heading. It consists of a 3-axis accelerometer, a 2-axis ...

[Muris] is pumping out the home lighting hacks. He developed this motion sensing module as an add-on to the IR switch we saw last week. There’s some kind of fuse box above his entry door and its white ...

The MPU6050 module has a total of 8 pins, of which at least 4 pins are necessary for the interfacing. VCC provides power for the module. Connect to the 5V pin of the Arduino. GND Ground is connected ...
