◆Product Overview
The Digital High Frequency Microwave Sensor with Low Power Consumption is used to detect moving human signals through the Doppler principle, including two parts: First, high frequency 5.8GHz microwave transceiver module, working in the C-band international common frequency, with lower wireless link propagation loss than X and K band, the module uses a needle antenna, integrated microwave oscillator and detector inside the module, with higher integration, the module directly outputs low impedance Doppler signal, transmitting power is only about 0. 025mW. Does not have any impact on the human body, the module through the United States FCC Part 15 Section 15.245 and the European CER&TTE EN 300440-1 V1.6.1 EN 300440-2 V1.4.1 certification; Second, MCU master circuit module, receives and amplifies the Doppler signal generated by the 5.8GHz microwave module, and then sendsit tothe MCU master chip for processing, in order to control the load switch state, because the signal processing is in the form of digital, making the product false positive rate is very low.The product signal output terminal directly outputs the high and low level signal, the user can directly use the signal, no need to develop the amplifier circuit again, easy to use, costeffective.
◆Features
Digital signal processing.
Strong resistance to radio frequency interference
The transmitting power is only about 3.54dBm, which does not cause radiation damage to the human body Uniform detection area
Low voltage, low power consumption, enter the working state immediately after starting
Automatic recognition of external light control value, to achieve no induction during the day, induction at night
Human body induction, repeated trigger
Output high and low level signal, easy to use
Small volume, easy to use with other circuits
