TSENHP Sure Action Pulsor Stress Sensor Single Pack

The Pulsor - The Pulsor is the most stable and versatile motion detector available anywhere. Decade for decade, indoors and outdoors, the Pulsor will outlast and outperform any other motion detector. The Pulsor is a motion sensing device that senses the physical flexing of whatever material it is epoxied to. When a person walks across the floor, the floor, and its supports, will bow downward as pressure is applied. They will then return to normal as the person steps off the beam. The Pulsor senses this flex (downward and upward), and a processor analyzes this change and responds by activating your security alarm or home automation system.
