This circuit is from the GLOLAB web page. The document referenced here includes an excellent design as well as an excellent tutorial on PIR devices. You've probably seen these devices in homes and ...

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 ...

The REDEYE-6A is an array sensor using pyroelectric ceramic. The manufacturing process is simpler than it is for a micro-bolometer. The ceramic plate is attached on top of the readout integrated ...

Murata's pyroelectric infrared (PIR) sensor is claimed by the company to be the world's smallest at 5.0 x 4.7 x 2.4 mm Hoofddorp, Netherlands: The latest version of Murata's pyroelectric infrared ...

The instrument is based around a pyroelectric sensor which detects between 7 to 12 microns. “Pyroelectric sensors are low-cost but have a high sensitivity and work at room temperature,” Hartwig told ...
