SR505 Miniature PIR Sensor Module
Category: Sensors
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.
