PIR Motion detector module
(DC
4.5~20V)
( retriggerable and non-retriggerable modes)
Specifications :
Detection method : Passive Infra Red (PIR)
(by the infrared radiation from human body)
Operating voltage : 4.5V ~ 20V DC
Operating temperature range : -15 °C ~ +70 °C
Standby current : 50 mA
Output : Normally low (0V). Active high (+3.3V).
Output current : (source) : 5 mA
Output timer : (default) 15 second
(adjustable
from 0.5~200Sec)
Disable time : 2.5 sec. (the
sensor is temporarily disabled when the output goes from high to
low)
Detection angle : 100 deg
Detection range : 7m adjustable
Board size : 32 x 24 mm
Power-up initialization :
When the circuit is powered up by
connecting to a DC power supply, there will be an approx. 1 minute
initialization period during which the output
may go high 0-3 times.
After this period, the output becomes stable & will remain low.
Any motion of human body in front of the lens will cause the output
to go high and stay high for about 15 seconds.
Trigger mode :
Retriggerable mode (H) {default}
: In this mode, multiple detections of motion within 15 seconds of each
other will maintain a continuous high output.
Non-retriggerable
mode (L) : When triggered by motion, the output will
go high and remain high for a duration set by the trimmer Tx
(default is a around 15 seconds)
