DFROBOT Gravity Digital Microwave Sensor for Motion Detection

The DFROBOT Gravity Digital Microwave Sensor is a highly effective solution designed specifically for motion detection applications. It offers non-contact detection, ensuring reliable readings that are not affected by environmental factors such as temperature, humidity, noise, air, dust, or light. Furthermore, it boasts a strong resistance to radio frequency interference, guaranteeing consistent performance in various settings. With its low output, it remains unharmful to humans, making it suitable for occupied spaces.

This sensor supports the detection of non-living objects and provides a wide detection range alongside high velocity capabilities. The detection range is continuously adjustable between 2 and 16 metres, offering excellent flexibility for different project requirements. It operates on a 5V DC power supply, with a typical operating current of 37mA and a maximum of 60mA. The plug and play 3-pin Gravity interface ensures straightforward integration into your existing setups.

The microwave sensor can be particularly useful when combined with other sensors to significantly enhance measurement accuracy. It is perfectly suited for measuring vehicle speed, door motion detection, automatic washing systems, production line material detection, and car reversing sensors.
