DFRobot SEN0395 mmWave Radar Sensor

DFRobot SEN0395 mmWave Radar Sensor senses the human presence, stationery, and moving people within the detection range of 9m. This 24GHz millimeter-wave radar sensor employs a separate transmitter and receiver antenna structure, Frequency-Modulated Continuous Wave (FMCW), and Continuous Wave (CW) multi-mode modulation. The SEN0395 mmWave radar sensor also detects static or stationary human presence such as a sleeping person. This sensor offers serial port and I/O port switch quantity as the two ways provided to the output detection results.

The SEN0395 mmWave radar sensor features strong sensing reliability, high sensitivity, small size, and is easy to be used or embedded in applications. This sensor offers a strong anti-interference ability and is not affected by snow, haze, temperature, humidity, dust, light, and noise. The SEN0395 mmWave radar sensor operates at 3.6V to 5V voltage range and -40°C to 85°C temperature range.
