SYH24A1 24G Millimeter Wave Radar 

Instruction Manual 

1. Principle

Millimeter-wave radar is a sensor that transmits and receives electromagnetic 

waves through a radar antenna and measures the amplitude and position of an 

object's movement. After analysis by the algorithm, the human body's 

breathing, movement, number of people, distance, direction and other 

information are judged. 

2. Application

The millimeter-wave radar is not affected by temperature, humidity, noise, 

airflow, dust, and light, and is suitable for use in harsh environments; suitable 

for the care of the elderly, management of hotels and guesthouses, 

management of office personnel, intrusion alarms, barrier prevention Hit 

reminders, population statistics, etc. 

3. Detection range

The area that the radar module measures human activity is within about 200 

square meters, the maximum sensing distance for object movement is less 

than 20 meters, the measurement breathing distance is within 5 meters, and 

the radar antenna has a measurement range of 80 ° horizontally and 30 ° 

vertically. It is a product that can measure different distances through different 

algorithms.
