Product Introduction

HLK-LD101L is a micro/motion sensing module designed based on X-band radar chip with a center frequency of 10.525GHz. The module design adopts fixed-frequency, directional transmitting and receiving antenna (1T1R), integrates the functions of intermediate frequency demodulation, signal amplification and digital processing, and opens the communication serial port at the same time, with the ability of delay setting, adjustable sensing range and light intensity detection, etc. It is convenient for customers to adjust parameters independently. It has the advantages of not penetrating walls, anti-interference, small size, good suppression of clutter and higher harmonics, high stability and consistency. This product is suitable for embedded concealed design, and is not affected by temperature/humidity, oil fume, water mist, etc. It can be widely used in intelligent lighting, security, home and other fields that require automatic sensing control.

Product Feature

Application Scenarios

 Smart lighting: garages, corridors, homes, offices, hotels, campuses, etc. 

 Smart Security 

 Smart home appliances 

 Smart electrical appliances, etc.

Input parameters

Output Parameters

 The initial value of the light perception is 255 (the light perception is off), which can be set and adjusted according to the actual needs of customers; 

 The perception distance can be adjusted according to customer needs. 

 The delay time is the time to keep the state after triggering, the default value is 5s, which can be set according to the demand; 

 Block time refers to the time when the output status is reversed and the trigger does not respond again. The default value is 1s. 

 Program definition output description: 

 O pin output - controlled by photosensitive; 1. If the standby brightness is set, the O pin will light up when there is no one at night, and the O pin will output low level when there is no one in the daytime; 2. If the standby brightness is set, when there is no one at night, the O pin will turn off the light for 0.2 seconds every hour to detect the ambient illuminance, and the O pin will turn off the light for 0.2 seconds after each sensing light is completed to detect the ambient illuminance. 

 O2 pin output - independent of photosensitive detection, not subject to photosensitive control; 1. If the standby brightness is set, the O2 is the standby brightness during the day and at night; 2. If the standby brightness is set, the O2 pin will turn off the light for 0.2 seconds every hour when there is no one at night and after each sensing light is turned on to detect the ambient illuminance, so as to ensure that the O pin can output the corresponding power according to the illuminance. The standby brightness value is set according to the percentage value, and the maximum value is 25, which means 25%.

Scope of percetion

• Different test environment or movement goals, the test results may be different 

• Metal shell will have a shielding effect on the radar electromagnetic wave, affecting the perception distance 

• The results of the above test are testing at the standard test site. The specific test environment and conditions can be consulted with related technical personnel. 

• There are errors in the scope of perception, and there will be certain uncertainty in the weak perception area
