The Gravity: Digital PIR Motion Sensor is designed for precise motion detection by sensing infrared radiation emitted from humans and animals. Utilizing passive infrared (PIR) technology, it effectively identifies changes in heat signatures within its detection range of up to 7 meters and a wide 100-degree angle. Operating at a voltage range of 3.3 to 5V, this sensor is perfect for home automation, including occupancy detection, security systems to trigger alarms, and energy conservation solutions that optimize power usage based on presence. Its compact design and seamless integration with Arduino and Raspberry Pi make it a versatile choice for developers and DIY enthusiasts.
How the Gravity: Digital PIR Motion Sensor Works
Detection Range of the Gravity: Digital PIR Motion Sensor Works
High Sensitivity and Precision
With a detection range of up to 7 meters and a wide 100-degree angle, this sensor effectively monitors larger spaces for precise motion detection.
When the PIR sensor detects motion, it outputs a high-level signal (the OUT terminal is at a high level). This high-level signal persists for a specified duration (High duration) before returning to a low level (the OUT terminal is at a low level). In continuous trigger mode (effective continuous trigger), the sensor maintains a high-level output as long as motion is detected. This immediate responsiveness is ideal for applications such as occupancy detection, where real-time monitoring is crucial.
Easy Integration
The Gravity: Digital PIR Motion Sensor employs a Gravity Interface, facilitating quick and straightforward connections to Arduino and Raspberry Pi. This plug-and-play capability simplifies the setup process, eliminating the need for complex wiring and configurations.
Low Power Consumption
Operating at a voltage range of 3.3 to 5V, this sensor is designed for energy efficiency, drawing only 15µA of current during operation. This low power consumption is especially beneficial for battery-powered applications, ensuring long-lasting performance without the need for frequent battery replacements.
