Gravity: Digital PIR Motion Sensor
Overview
The SEN0171 is a Pyroelectric Infrared (PIR) motion sensor module built on the DFRobot Gravity platform for rapid prototyping. It utilizes the AM412 sensor to detect infrared radiation emitted by humans or animals, providing a digital output signal when movement is sensed within its detection range. The module is designed for low-power operation with a typical running current of just 0.015mA.
Why Choose This Part
The module features an onboard indicator LED for immediate visual feedback during testing and a 100mA output drive capacity. Its wide operating temperature range of -20C to 85C and low current consumption make it suitable for various environmental conditions and battery-operated applications.
Applications
Key Specifications
Getting Started
Connect the module to any microcontroller with a digital I/O pin using the included Gravity PH2.0-3 cable. In your code, configure the connected pin as a digital input and monitor for a high signal (3V) to detect motion. The sensor is plug-and-play with Arduino-compatible boards and requires no external libraries for basic operation.
