PIR Motion Sensor ( HCSR501)

The HC-SR501 PIR Motion Sensor is an easy-to-use passive infrared module designed for detecting motion from humans or animals in robotics, home automation, and DIY electronic projects.

Key Features:

• Reliable Motion Detection: Detects movement within a 3m to 7m range with a sensing angle under 120°.

• Adjustable Range & Delay: Onboard potentiometers allow custom setting of detection distance and trigger delay time (5s to 300s).

• Microcontroller Compatible: Provides a 3.3V TTL high output that directly connects to Arduino, Raspberry Pi, ESP32, and 5V–20V power sources.

• Low Power Consumption: Static current under 50µA makes it ideal for battery-powered setups.

Quick Specs:

• Operating Voltage: DC 4.5V – 20V

• Output Signal: High 3.3V / Low 0V

• Detection Distance: 3m – 7m (Adjustable)

• Dimensions: 32mm x 24mm
