## Description

DFROBOT mmWave Radar - Human Presence Detection Sensor (9 Meters)

## Features

- 【24GHz High Precision Stillness and Motion Detection】: With the Doppler radar technology and 24GHz working frequency, combined with FMCW and CW multi-mode modulation, this mmWave Radar sensor can accurately detect all movements, micro-movements, and extremely weak movements within a 9-meter range. Whether it's subtle human movements or stillness and sleep states, this sensor can accurately perceive them.
- 【Compact Size, Easy to Integrate】: The mmwave sensor's size is only 24*28mm, and it uses a 1Tx1Rx antenna structure, which is very suitable for integration into various systems or mobile devices, providing great convenience for various projects.
- 【Strong Anti-interference Ability (From -40 to 85℃)】: This mmwave presence sensor has outstanding anti-interference ability and can work stably in an environment of -40~85℃. Whether it's snow, fog, haze, temperature, humidity, dust, light, or noise, none of these can affect its working efficiency, ensuring stable performance in any environment.
- 【Wide Range of Application Scenarios】: Due to its high precision and strong anti-interference ability, this presence sensor is widely used in collision warning for autonomous driving cars, human activity monitoring in smart homes, precise control in industrial automation, non-contact monitoring in healthcare, inventory management in retail and logistics, obstacle avoidance and positioning in drones.
- 【High Flexibility with Various Output Options】: This human presence sensor provides two types of sensing result output methods. You can choose to output through the serial port or through the I/O port, which is very flexible and easy to expand. At the same time, it provides various available example codes that can meet the needs of makers in different projects.
