The SR505 is a miniature PIR module which uses a pyroelectric sensor similar to the one found in the common SR501 but in a more compact form factor. It can be powered from a 5 to 12V supply and when triggered its output pin will go high (3.3V) for approximately 8 seconds before returning back to 0V. This makes it suitable for directly interfacing to both 3.3 and 5V microcontrollers.
Product code: HCSENS0048
Supply voltage: 4.5 to 12V
Output voltage: 3.3V (triggered) / 0V (un-triggered)
Quiescent current: ~80uA at 5V
Trigger on time: ~8 seconds
Sensor angle: 100 degree cone
Sensor range: ~3 meters
Operating temp: -20 - +80 degrees
Lens diameter (mm): 10mm
PCB dimension (mm): 23.5 x 10.3
Overall length: 40mm inc header and sensor.
