PIR Motion Sensor

Overview
The PIR (Passive Infra-Red) Sensor is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin.A PIR detectorcombined with a fresnel lens are mounted on a compact size PCB together with an analog IC,SB0081, and limited components to form the module. High level output of variable width is provided.

PIR Motion Sensor:
Features:
  • Detection range: 2-3 meters
  • Settling time: 60 seconds
  • Compact size (24 x 32 mm)
  • Supply voltage: dc3v-5v
  • Current drain :< 50ua
  • Voltage output: high/low level signal: 0-3. 3v
  • High sensitivity
  • Delay time: 5s-18 minute(as customer requirement)
  • Operation temperature: -15oc -70 oc
  • Infrared sensor: dual element, low noise, high sensitivity
  • Light sensor: cds photocell (can be add as customer requirement.
