3 pièces HC-SR501 SR505 Mini Infrarouge Module détecteur de capteur PIR Module de détection corporelle Interrupteur à capteur Humain

[High Performance] High efficiency: low power consumption, small size, easy to install. High sensitivity and high reliability, fast response. Stable reliability, ultra-low voltage operating mode. Strong vibration resistance, good electromechanical performance, long signal transmission distance.

[Automatic Induction] Fully automatic induction, excellent sensitivity.

One type of trigger mode makes it easy to use. Upon entering the detection range, the output is high; when people automatically leave the high sensor range, the output is low. [Repeatable Trigger] The sensor output is high, with a delay time. When there is human activity in the detection zone, the output remains high until the output returns to low after a variable delay (the advanced sensor module automatically detects the human body after each activity, with a delay period and the last time an event occurred marking the start of the timer). [Wide Range of Applications] Widely used in various automatic sensing electrical devices, body induction lamps, body sensor toys, especially battery-powered automatic control products.
