PIR Motion Sensor Detector Module

Description:

HC-SR501 is based on infrared technology, automatic control module, using Germany imported LHI778 probe design, high sensitivity, high
reliability, ultra-low-voltage operating mode, widely used in various auto-sensing electrical equipment, especially for battery-powered automatic
controlled products.

Specification:
◦ Voltage: 5V – 20V
◦ Power Consumption: 65mA
◦ TTL output: 3.3V, 0V
◦ Delay time: Adjustable (.3->5min)
◦ Lock time: 0.2 sec
◦ Trigger methods: L – disable repeat trigger, H enable repeat trigger
◦ Sensing range: less than 120 degree, within 7 meters
◦ Temperature: – 15 ~ +70
◦ Dimension: 32*24 mm, distance between screw 28mm, M2, Lens dimension in diameter: 23mm

Application:
Automatically sensing light for Floor, bathroom, basement, porch, warehouse, Garage, etc, ventilator, alarm, etc.

Features:
Automatic induction: to enter the sensing range of the output is high, the person leaves the sensing range of the automatic delay off high,
output low.
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.

The 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 200 seconds.
 
The setting 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.
