DFRobot Gravity Digital PIR (Motion) Sensor for Arduino - PH2.0-3 Interface
The DFRobot Gravity Digital PIR Sensor is a low-power, integrated motion detection module compatible with 3.3V/5V Arduino and other microcontroller platforms. It outputs a digital high/low signal upon detecting infrared radiation from moving bodies within its 100° field of view.
Features
- Ultra-Low Power Consumption: Operates at just 15µA, ideal for battery-powered IoT and security projects.
- Integrated Digital Design: Combines pyroelectric IR detector and conditioning circuitry for simplified interfacing.
- Wide Operating Range: Functions reliably from -20°C to 85°C for robust environmental performance.
- Gravity-Compatible Interface: Features a PH2.0-3 connector for plug-and-play wiring with DFRobot Gravity ecosystem cables.
- Adjustable Sensitivity: Allows fine-tuning of detection range and trigger conditions for specific application needs.

This sensor utilizes a passive infrared (PIR) pyroelectric element to detect changes in infrared radiation, typically emitted by warm bodies in motion. The onboard chipset digitizes the analog signal, providing a clean, debounced 3.3V TTL-level output that transitions from low (0V) to high (3V) upon detection, simplifying integration with microcontrollers like Arduino, ESP32, or Raspberry Pi.
Its compact, integrated design eliminates the need for complex external circuitry required by conventional PIR sensors, offering higher reliability and a smaller footprint. The module is engineered for long-term stability in a wide temperature range, making it suitable for both indoor and protected outdoor applications.
