HLK-LD1020 Microwave Motion Detection Radar Module

The motion sensor module is designed based on the radar chip, with a central frequency of 1 0.525 GHz, which works to detect movement in a certain space. The design has fixed frequency, directional transmit and receive antennas (1T1R) and also integrates functions such as medium frequency modulation, signal amplification and digital processing; in addition, it has the ability to adjust the delay.

The chip can directly provide diagnosis results without the need for a computer. In the pulse power supply mode, the power consumption of the module is at the microamp level, which is mainly suitable for low-cost and low-power applications. This sensor is not affected by temperature and humidity, smoke, oil, fog, water, etc.

Be sure to use a drive power supply that meets the standards for output voltage, current, and ripple factor; also, the drive power supply is unstable and the electromagnetic radiation is too strong, causing false alarms, and automatic initiation of the radar module cycle. .

Note: The sensor should be installed in a place away from the electromagnetic field to avoid damage caused by electromagnetic interference, and it should also be installed in a place away from objects that are constantly rotating or oscillating (such as electric fans, etc.) Avoid errors in practice.
