STR5812 is an ultra-low-cost motion sensing sensor chip that operates in the 5.725-5.85GHz frequency band. It senses object movement based on the Doppler effect. It has sensitive reception, low power consumption, strong common mode suppression, and a wide operating temperature range. Features.
The STR5812 chip has a built-in low-noise voltage-controlled oscillator (VCO), which can adjust the working frequency band and avoid co-frequency interference.
The STR5812 registers are configured through the 2-wire I2C interface.
