HC-SR501 PIR Motion Sensor Detector - Infrared Motion Sensor 4.8-20V DC Wide Voltage, 0.5s-200s Adjustable Delay, Dual Trigger Modes for Home Security, Energy Efficiency & IoT Devices (Pack of 3pcs)

HC-SR501 PIR Motion Sensor Detector - Infrared Motion Sensor, Adjustable Delay, Dual Trigger Modes (Pack of 3pcs)

It can automatically and quickly open various types of incandescent, fluorescent lamps, buzzer, automatic doors, electric fans, automatic washing machine and dryer Machines and other devices, is a high tech products. Especially suitable for enterprises, hotels, shopping malls, warehouses and family aisles, corridors and other sensitive Sense of region, or for the security zone automatic lighting, lighting and alarm systems 3 X HC-SR501 PIR infrared motion sensor modules With induction blocking time (default setting: 3-4 seconds): After each induction output (high level to low level), the induction module can set a blocking time immediately, and sense in this time period The device does not receive any induction signal. This function can realize the interval work (induction output time and blocking time), and can be applied to interval detection products; at the same time, this function can effectively suppress various interferences generated during load switching.

Key Features
