Low-power Doppler radar module wireless radar light control module intelligent induction, wireless emission light control radar sensor switch module is a 433Mhz wireless transmitter switch developed based on microwave radar and light control scheme, transmits high-frequency electromagnetic waves through the radar chip, and receives Echo signal filtering, mixing frequency. After amplification, it is amplified by the baseband circuit, judged and controlled by the light sensing system, and wirelessly sends a signal to the host to control the state of the lamp.
The wireless radar light control module integrates a 5.8GHz radar chip and a high-gain microstrip antenna, which has the characteristics of high sensitivity, good consistency, stability and reliability, safety and energy saving, good clutter and high harmonic suppression effect, etc. It is widely used in various fields of intelligent lighting. This kind of lighting place provides a good solution for IoT applications.
The low-power induction module solution, the Doppler radar module adopts the principle of capacitive non-contact space induction, that is, there is a capacitance between any two conductive objects. The induction module uses the size of the capacitor and the conductivity of the medium, as well as the size of the plate, the conductivity is small, and whether there is conductive material around the plate. When a human finger approaches, the PCB or in the sensing area, the size of the capacitor changes due to the conductivity of the human body. After the capacitive non-contact module detects that the capacitance value has risen sharply, it outputs a switch signal.
Scope of application: music floor tile induction, various sizes of home appliances, induction wake-up product design, induction faucet, clothing (kitchen) cabinet induction lamp, intelligent induction trash can (replace IR induction, lower power consumption and lower cost than IR, etc.).
The Doppler radar module has self-developed chips, fixed-frequency, directional high-gain microstrip antenna and letter induction demonstration module number processing circuit and algorithm, onboard integrated IF demodulation, spectrum energy analysis, signal amplification, digital processing and other technologies , its sensing distance, accuracy and delay can be adjusted according to customer needs. This module can detect large movements such as walking and running, and small movements such as shaking the head and swinging arms in normal life. Signals, human breathing and other vital signs, that is, the detection of human presence, can be applied to smart hotels, smart elderly care, smart lighting, smart security, smart home and other fields.
