HC-SR501 Adjust IR Pyroelectric Infrared PIR Module Motion Sensor Detector Module

HC-SR501 Adjust IR Pyroelectric Infrared PIR module Motion Sensor Detector Module for arduino

Descriptions:

1. Automatic induction: when someone enters its sensing range input high, people leave the sensor range automatic delay off high. Output low
2. Photosensitive control (optional): module is reserved for the location, you can set the photosensitive control, daytime or light sensing. The photosensitive Control optional features not installed at the factory photoresistor. If necessary, please purchase separately photoresistor install it yourself
3. Two trigger modes: L can not be repeated, H can be repeated. Jumper selectable, default is H
A. not repeat the trigger mode: the sensor output high, the delay time has elapsed, the output automatically from high to low.
B. repeatable trigger mode: the sensor output high, the delay period, if human activities within its sensing range, the output will always remain high until people leave only delay the high level goes low (sensor module detected after every activity of the body's automatic postponed a delay period of time, and the last time activities as the starting point of the delay time)
4. induced blockade time (default setting: 0.2 seconds): sensing module in every sensor output (high to low) followed by set up a blockade of the time, in this period of time the sensor is not receiving any induction signal. This feature can be achieved both of the (inductive output time and the blocking time) interval can be applied to the interval detection products; This feature can effectively suppress the various interference generated in the process of load switching
5. wide operating voltage range: default Voltage DC5V to 20V
6. micro-power: quiescent current of 65 microamps, particularly suitable for battery- powered electrical products
7. output high signal: easy to achieve docking with the various types of circuits
