PIR sensor




“• Size: Rectangular
• Output: Digital pulse high (3V) when triggered (motion detected) digital low when idle (no motion detected). Pulse lengths are determined by resistors and capacitors on the PCB and differ from sensor to sensor.
• Sensitivity range: up to 20 feet (6 meters) 110° x 70° detection range
• Power supply: 5V-12V input voltage for most modules (they have a 3.3V regulator), but 5V is ideal in case the regulator has different specs
