This Arduino-based burglar detection alarm uses a PIR sensor to detect motion. When movement is sensed, an LED lights up and a piezo buzzer sounds an alert. Ideal for security applications, this ...

We are using a HC-SR501 PIR Sensor, an LED (which will glow whenever there is a motion infront of the sensor) and resistor. Vcc PIN of PIRs connected to the positive terminal of the 9v battery, GND ...

At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a pyroelectric sensor module which developed for human body detection. A PIR detector combined with a fresnel lens are mounted on a ...

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.

[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… ...
