Smart Electronics HC-SR312 Human body sensing infrared sensor PIR infrared module HC-SR312
Technical Parameters1. Working voltage: DC 2.7-12V; 2. Static power consumption: <0.1mA; 3. Delay time:2sec; 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 lens

Functional features

a. Enhanced anti-interference, internal digital signal processing, direct high and low level output.

b. Repeatable trigger mode: that is, after the induction 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 time, 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 last activity as the starting point of the delay time).
