Product Description LD6002H is a 60G radar module based on FMCW radar mechanism. It detects radar reflected from the human body and combines high-precision radar signal processing algorithm to achieve real-time respiratory and heart rate frequency monitoring of specific groups of people. It is mainly used in scenarios such as smart home, health management and smart health care to achieve non-contact respiratory and heart rate measurement. Product features Operating frequency: 60G (58-62GHz) Transmitting power: 8dBm Modulation mode: FMCW Antenna gain: 4dBi Detection angle: azimuth 60 / pitch angle 60 Detection distance: 0.8~1.5m (breathing heartbeat/chest) Establish detection time: 1min Maximum number of people to be detected: 1 person Power supply requirement: 5V (Typ.)/ 800mA Dimensions: 38x40mm Operating temperature: -40~+85 Ambient temperature: -40~+125 Data format: Serial port ASCII output Package form: default 1.5mmx4Pin female socket Color: Green Material: ABS Package Contents: 1 set of Respiration and heartbeat test module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
