Passive Infrared Sensor Module 2s Not Adjustable for Home Security System
This unit features an improved digital sensor with enhanced delay
time adjustment capabilities, supporting a configurable range from 2
seconds to 70 minutes. It integrates a built-in light sensor with
adjustable sensitivity and is suitable for both indoor and outdoor
mounting applications. The detection range is also user-adjustable. The
module provides a standard TTL output signal, compatible with
microcontroller interfaces and suitable for applications such as
lighting control.
