Liveness sensor function and characteristics Radar sensor switch Smart home application

The function and characteristics of the living body sensor radar sensor switch smart home application, the living radar body sensor is a moving object detection device designed using the principle of the Doppler effect. Detects whether the position of an object moves in a non-contact manner and generates corresponding switch actions. The product has strong anti-interference ability and is not affected by temperature, humidity, light, airflow, dust, etc. It can be installed on non-metallic shells such as plastic, glass, wood, etc. of a certain thickness, and can be installed in very convenient application equipment control , environmental auxiliary lighting control, underground parking lot lighting and other fields, does not affect its detection function.

Live sensor functions and features:

1. How it works: After the induction switch is turned on, if there is human activity during the delay, the switch will continue to turn on until the person leaves and the delay is enabled.

2. Intelligent delay: After the switch detects all the activities of the human body, the delay time of the last human activity will automatically start along a cycle.

3. Photosensitive adjustment: control whether the switch works according to the intensity of external light, so as to achieve the effect of energy saving.

Notes on adjusting the liveness sensor:

1. The function of light control is that when the light exceeds a certain intensity, the radar cannot detect it. Therefore, in order to perceive in brighter places, the light must be adjusted to a larger dimming range.

2. The selection of each switch should refer to the corresponding space. Large-distance switches are suitable for outdoor or large locations, and short-distance switches are suitable for small spaces.

3. The induction switch has a self-test output every time it is activated. After the delay adjustment, wait until the next induction activation.

Living sensor radar sensor switch home application, radar sensor is also very common in the home, many home decoration will also have this sensor switch light, let's take a look.

Automatic control products based on radar technology, when someone enters the sensing range, special sensors will detect changes and automatically connect the load. If there are no sensors, the load will continue to connect. The delay will automatically turn off the load when people leave. Realize human lights, human lights, safety, convenience, environmental protection, energy saving, reflecting humanized care. It is usually used for automatic control of street light switches in public places. It consists of radar detection circuit, signal processing circuit, signal output control switch circuit, and main components of power supply circuit. The radar signal processing integration mainly completes the radar signal processing. The circuit power supply supplies power to the sub-circuits of the designed circuit according to the requirements of each part of the circuit to ensure the stability of the circuit. The radar induction detection switch has long detection distance, wide application range and anti-interference ability. Strong, stable performance and so on.

The relevant specifications must be strictly followed during the installation process. The installation of the live sensor is not complicated, but needs attention. The installation of radar sensor switches can be divided into external and embedded sensor switches. The external induction switch can be installed directly outside the lamp without affecting its detection function.

The installation instructions are separately connected to the FireWire. neutral and neutral. After connecting the wiring, install the switch to the top. The detection range of the left and right sides of the switch is larger than that of the upper and lower sides. Therefore, during installation, the two axes should be as perpendicular to the direction of people's walking passage as possible to obtain better detection results.

Power up after installing the switch. If the ambient light is sufficient, the light bulb will flash, and after 1 minute initialization, the switch will enter the monitoring state, cover the ambient light with an object, and the switch will enter the working state. If people don't leave the area, the switch will continue to work. When people leave, the switch automatically delays the load from turning off. If the delay time or material sensitivity value is not satisfied, it can be adjusted through the back of the sensor switch. Delay time and light sensitivity value can be adjusted.

The home application of the living sensor radar sensor switch is introduced here. For more information, you can continue to follow us.
