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.

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 project was for an engineering design class at the University of Houston Clear lake. There were also two other people working on this project along side myself. All parts were bought on Amazon.

If you are thinking about building yourself a burglar alarm or you are thinking about Automating lights in your room, then you should definitely consider using an HC-SR501 Passive Infrared Sensor or ...

The LSM320HAY30 integrates a three-axis digital accelerometer with a two-axis analog gyroscope in a single module, a feat that allegedly improves performance, boosts reliability, reduces size, and ...

Designed for use in the extremely small custom-printed circuit boards typical of such designs, the module measures 17mm x 17mm, about the size of a standard CR2032 coin cell battery (Figure 1). All ...

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 ...

The main aim of this mini-project is to demonstrate the working of a PIR motion-based light bulbs. This is to mainly minimize energy consumption and save electricity bills. Sometimes people forget to ...
