The body has a sensor built-in WIFI module, illuminance sensor, 5.8GHz microwave mine (or infrared sensor head), 24GHz microwaveradar module, using dual microwave radar (or microwave radar + infrared sensor) configuration. The 5.8GHz (or Infrared) is used ashuman intrusion detection and the 24GHz micromotion detection complement each other to prevent the problem of false triggering ofa single radar and weak motion detection. It is not affected by the surrounding environment such as infrared/ultraviolet light,brightness, temperature, humidity and visible light fluctuations, making the detection more accurate. The human body sensor candetect and identify moving, micro-moving and stationary human bodies and objects; The built-in microwave sensor uses FMCW FM continuous wave, combined with radar signal processing and built-in intelligent human body sensing algorithm to detect the human body target in the set space and update the detection results in real time. According to various application scenarios, various intelligent control functions are realized. For example, with the scene setting of graffiti IOT application, it can be set into the situational application occasions under the conditions and states of human, unmanned, lighting, timing (such as the automatic control of power supply equipment, light on/off/brightness/color temperature control system, air conditioning control system,etc.); The built-in light sensor can display the light reference value in real time, which can be used as the trigger condition for light changes. You can set the trigger delay time when no one is present according to the actual usage (you can also set the delay time in the scene). In addition, the induction sensitivity and induction distance can be adjusted according to the actual use of the site. Attention: In a certain distance range, the strong moving objects outside the glass and wood doors and Windows also have a certain chance to be detected, although the detection effect outside the doors and Windows is greatly weakened, but it is still recommended to install slightly away from the wood/glass doors and Windows, at the same time, when to detect the unmanned state, there should be no unnecessary moving objects in the detected space. Such as curtains blown by the wind, active pets, rotating fans and so on.
