5.8G microwave induction module solution

Core chip model STM8
AT701 microwave sensor is used to detect the signal of moving human body through the principle of Doppler.



It works on the international universal frequency of C-band and has lower wireless link propagation loss than X and K-band.



The module integrates a microwave oscillator, a detector and a high-gain intermediate frequency amplifier, which has a higher degree of integration.



The module directly outputs low-impedance Doppler signals. The user only needs to connect the intermediate frequency output to the input of the controller to use it, without the need for the user to develop an intermediate frequency amplifier circuit twice.

An omnidirectional antenna is installed on the top of the module, which can detect 360° in all directions. The operation is simple and cost-effective.
