This Gravity Digital PIR (Motion) Sensor is a great choice for Arduino and Raspberry Pi projects. It can sense motion, perfect for detecting if a human enters or leaves its range. Compact, affordable, low - power, and easy to use, it won't wear out easily. That's why it's commonly used in home and business appliances. It can detect infrared signals from humans or other animals, triggering with movement, and is suitable for various motion - detection scenarios. Unlike traditional pyroelectric infrared sensors, this one is integrated, with a small size, high reliability, low power consumption, and a simple peripheral circuit. To make it even easier to use, it has a Gravity Interface for plug - and - play. It's best paired with an Arduino IO expansion shield. It works at 3.3V, making it compatible with Raspberry Pi, Intel Edison, Joule, and Curie. Applications include moving human detection, occupancy detection, and security systems. Specifications: Input Voltage 3.3 - 5V (6V max), Working Current 15uA, Working Temperature - 20 to 85 °C, Output Voltage High 3V and Low 0V, Output Delay Time (High Level) about 2.3 - 3 seconds, Detection angle 100 °, Detection distance 7 meters, Output Indicator LED (lights up when output is HIGH), Pin limit current 100mA, Connection Interface PH2.0 - 3, Module size 30mm x 22mm (1.18'x0.87'). Documents include WiKi Doc and Schematic. Shipping list has 1 Gravity Digital PIR Sensor and 1 Gravity Digital Cable. A sample project is an Arduino Power outlet with exposed pins.
Using the Gravity Digital PIR (Motion) Sensor is a breeze. First, connect it to your Arduino or Raspberry Pi using the Gravity Interface for easy plug - and - play. If you're using an Arduino, pair it with an Arduino IO expansion shield for the best performance. The sensor can work at 3.3V, so it's compatible with multiple devices. To start detecting motion, just place the sensor in the area you want to monitor. It will detect infrared signals from humans or animals moving within its 7 - meter detection distance and 100 - degree detection angle. The output indicator LED will light up when there's motion detected. When using, make sure the input voltage is between 3.3V and 5V, with a maximum of 6V. The working current is 15uA, so it won't consume much power. The sensor can operate in temperatures from - 20 °C to 85 °C. For maintenance, keep it clean and free from dust. Avoid exposing it to extreme conditions. Also, don't exceed the pin limit current of 100mA to prevent damage.
