3pcs HC-SR312/501 Human Body Infrared Sensing Module Mini PIR Module for Arduino

Module Description:
AM312 human body sensor module: is based on passive human infrared technology, digital intelligent automatic control products, high sensitivity, strong reliability, widely used in various types of automatic sensor electrical equipment.
Second, the technical parameters:
1. Operating voltage: DC 2.7-12V;
2. Static power consumption: <0.1mA;
3. Delay time: 2 seconds;
4. Blocking time:2sec;
5. Trigger mode:repeatable;
6. Sensing range: ≤100 degrees cone angle, 3-5 meters; (according to the specific lens)
7. Operating temperature: -20 - +60℃.
8.PCB external size:10mm*8mm
9.Module lens: small lensFunctional features:
a. Enhanced anti-interference, internal digital signal processing, direct high and low level output.
b. Repeatable trigger mode: that is, after sensing the output high level, in the delay time period, if there is a human body in its sensing range of activities, its output will remain high until the person leaves the delay before becoming low level (that is: the induction module detects each activity of the human body will be automatically postponed after a delay time period, and the time of the next activity is the starting point of the delay time).
