The HLK-LD303-24G IoT millimeter wave radar module can be used to detect moving targets in a small range, and output distance and high and low level information, and is not affected by temperature, humidity, airflow, dust, noise, brightness, etc. Strong anti-interference ability, can penetrate acrylic, glass, plastic and other thin non-metal materials.
HLK-LD303-24G has industry-leading excellent performance, small size, higher accuracy, and low power consumption. It can provide customers with ideal and better performance object movement monitoring solutions.
TTL serial port, default baud rate 115200, data bit 8, stop bit 1, no check bit. Fixed query command (HEX): 55 5A 02 D3 84. The module defaults to the query mode, sending a fixed hexadecimal query command, and the module reports distance and other data after receiving it successfully.
* The module detects relative moving objects in the area, and outputs information such as the distance of the object, and completely stationary targets are not detected.
* The default query mode (protocol 6), if you need continuous automatic reporting, change the protocol to 7. (Use the host computer to modify or send the instruction directly BAAB00F600070055BB)
* If the module design shell, the best distance between the radar antenna surface and the shell surface is 6mm, and the thickness of the shell is about 2~3mm. The shell material can not use metal or metal-plated paint. It is recommended to use PC or plastic or steel Wait.
