My Initial tests (using the regulated 5VDC power supply) found it works well enough for my needs. In my quick estimation, the Grove-mini PIR motion sensor module (v1.0) is a compact and cost effective ...

HC-SR501 PIR Motion Sensor Module Pinout. The HC-SR501 module has three pins. The silkscreen of the module is hidden by the Fresnel lens, so refer to the following pinout given below. Apply power 5V – ...

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 ...

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 ...

The custom PIR sensor module allows you to detect motion using passive infrared technology. By integrating it with Home Assistant, you can automate various tasks based on motion detection, such as ...

The module adds and on-board ceramic antenna, DC-DC power mode configuration, as well as up to 27 programmable general-purpose input/outputs (GPIOs). The integration of the PIR sensor in the module ...

Module provides integration and flexibility for passive infrared (PIR)-based motion detection applications including customer sensing, lighting control and other energy management purposes. The ...

This breadboard compatible package combines an ESP32-S2 module with a top-mounted PIR sensor, making it a turn key solution for all sorts of motion sensing projects.

This paper presents a wireless communication system utilizing a 433MHz RF module alongside human presence detection using a Passive Infrared (PIR) sensor. The system is designed to enable real-time ...
