Passive IR Sensor, Wide Angle, Adjustable Sensitivity (ST-00081) US$11.99

28032
Passive IR Sensor, Wide Angle, Adjustable Sensitivity (ST-00081)


The SimplyTronics ST-00081 Wide-Angle PIR Sensor features a detection angle of 180 degrees, making it ideal for applications where you need to track movements across a large, open area. This sensor is a pyroelectric device that detects motion by sensing changes in the infra-red levels emitted by surrounding objects. When motion is detected, the sensor generates a High signal on its output pin and lights an indicator LED.

This PIR Motion Sensor Board can be connected to a 3.3V or 5V microcontroller. Demo code is available for BASIC Stamp, Propeller and Arduino.

It has a potentiometer for fine-tuning its sensitivity, and a "night mode" jumper that enables a light sensor which will turn off the motion sensor during the day. The motion sensor also can be enabled/disabled externally via the EN pin.

Wide-Angle PIR Sensor Features

  • Single-bit High/Low output
  • Small size and mounting holes for easy concealment
  • On-board LED
  • Power 3V to 6V DC operation; current draw 150A idle, 3mA active (no load)
  • 30mA active (0Ω resistor) high current draw
  • Detects movement up to 30 ft away
  • 180 detection angle for widespread motion detection
  • Adjustable sensitivity to tune for different operating conditions
  • User-selectable "night-time mode" for detecting motion only in decreased lighting conditions
  • 4-pin SIP package perfect for breadboard-friendly projects
  • Dimensions: 1.42 1.42 0.79 inches (36.0 36.0 20.2 mm)
  • Operating temperature range: 32 to 122 F (0 to 50 C)

See the ST-00081 Documentation Page for detailed specifications, dimensional drawings, and demo code.
