PIR Motion Sensor Detector Module
is based on infrared technology, automatic control module, using
Germany imported LHI778 probe design, high sensitivity,
reliability, ultra-low-voltage operating mode, widely used in various auto-sensing electrical equipment, especially for battery-powered automatic

◦ Dimension: 32*24 mm, distance between screw 28mm, M2, Lens dimension in diameter: 23mm
Automatically sensing light for Floor, bathroom, basement, porch, warehouse, Garage, etc, ventilator, alarm, etc.
Automatic induction: to enter the sensing range of the output is high, the person leaves the sensing range of the automatic delay off high,
Photosensitive control (optional, not factory-set) can be set photosensitive control, day or light intensity without induction.
Temperature compensation (optional, factory reset): In the summer when the ambient temperature rises to 30 ° C to 32 ° C, the detection
distance is slightly shorter, temperature compensation can be used for performance compensation.
PIR Sensor module allows you to sense motion. It is almost always
used to detect the motion of a human body within the sensor's range.
It is often referred to used "PIR", "Pyroelectric",
"Passive Infrared" and "IR Motion" sensor.The
module has an on-board pyroelectric sensor, conditioning circuitry
and a dome shaped Fresnel lens.The PIR sensor module provides an
output "HIGH" when a human body is detected within its
range and an automatic Delay "LOW" when the body leaves its
range. The delay time is adjustable using the potentiometer on-board.
The minimum delay time that can be set is 5 seconds and maximum of
time potentiometer is also provided on-board to set the setting
time during which the sensor does not
respond to any change in motion. The minimum blocking time that can
be set is 2.5 seconds and maximum of 10 seconds.
