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 ...

I try to make the PIR sensor module without using the commercial IC which has all the functionality such as normal-mode, re-triggering and turned on only at the dark environment. This is very hard to ...

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 ...

HC-SR501 PIR Sensor Module Onboard Parts. The HC-SR501 sensor consists of various components, and the parts marking of the PIR sensor module is shown below. BISS0001 PIR Controller. At the heart of ...

The PIR sensor will sense any motion in the range of 6 meters and if the motion is detected, it will send a signal to the microcontroller. Arduino will then use a GSM module to first send an SMS to ...

PIR sensor modules usually have a 3-pin connection: Vcc (+) , Output, and Ground (-) . The pinout may vary, so it is recommend to check the manufacturer’s datasheet to confirm the pins. Besides PIR ...

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sens… ...

The Amplifier IC is used to amplify the Output from Dog Barking Sound Module. The Alarm circuit consists of an Arduino Nano, PIR Motion sensor, LM386 Amplifier IC, Speaker, NPN Transistor, and a ...
