SKU: SEN0395
This 24GHz mmWave radar sensor uses FMCW/CW multi-mode modulation and separate Tx/Rx antennas. It detects moving, micro-moving, or stationary humans (e.g., sleeping people) by emitting waves, converting reflections to signals, processing via algorithms, and solving target info. Outputs are via serial port or I/O switch. Features: high reliability, sensitivity, small size, easy to use/embed.

FAQ
Pay attention to the beam angle in the wiki page, the beam angle faces the detected problem, the antenna of the sensor faces the measured object, and the recommended beam angle: 100*40° (width*height).
Supports GPIO output, supports serial port output, and does not need pull-down resistors when outputting, and can be directly connected to the main control board.
No, the sensor detects movement of all objects within range by detecting mmWave radar and is very sensitive.
1. Due to the high sensitivity of this millimeter-wave radar sensor, please ensure that the sensor is fixed firmly when using it. When holding it, the sensor will continuously output high level due to slight shaking.
2. Please try to change the sensor measurement range in the code or serial port settings, and make sure that there is no object moving within the range, and check whether the sensor value returns to normal.
Our tutorial reveals a certain degree of penetrability for wood. However, the properties of electromagnetic waves dictate that the higher the frequency, the weaker its ability to penetrate through walls. Therefore, the 24 GHz mmWave possesses a certain degree of wall-penetrating ability, albeit not particularly strong. It is recommended to avoid thick obstructions as much as possible when using it.
