Hi-link 10G radar sensing module HLK-LD1040C low-power micro motion intelligent sensing sensor IFC output

Product Introduction

HLK-LD1040C is a motion sensing module designed based on an X-band radar chip, with a center frequency of 10.525GHz. This module is designed with fixed frequency, directional transmitting and receiving antennas (1T1R), integrating functions such as intermediate frequency demodulation, signal amplification, and digital processing. It has the ability to set delay, adjust sensing range, and detect light intensity. This product has the advantages of not penetrating walls, anti-interference, small size, good suppression of clutter and high-order harmonics, high stability and consistency. The module initialization time is short, and it also has a fast inspection mode. It is easy to install and test in lighting fixtures, which can effectively accelerate production testing. This module is mainly aimed at low-cost application fields.

This product is suitable for embedded concealed installation and is not affected by temperature/humidity, oil fume, water mist, etc. It can be widely used in various types of lamps, such as bulb lights, tube lights, ceiling lights, etc.

Application scenarios

Smart Lighting: Home, Office, Lighting, Pet Supplies, etc

Product paraments

• The delay time is the time to maintain this state after triggering, with a default value of 5 seconds;

• The blocking time refers to the time it takes for the output state to flip and trigger a non response again, with a default value of 2 seconds;

• There are two types of startup initialization for different software configurations:

1. Description of initialization status without fast detection mode: After the module is turned on and the O port output is high for 1 second, it remains low for 7 seconds before starting normal detection mode

2. There is a description of the initialization status of the fast detection mode: when the module is turned on, the O port outputs 3 high (1s) and low (0.5s) levels, and after another 5 seconds, it enters the induction mode. The first induction is the fast detection mode test

(The induction delay is fixed at 3 seconds), then enter the normal detection mode.
