BM02S
The BM02S is a piezo-resistive pressure sensor and an ADC interface. It provides 16bit word data for pressure and temperature related voltage. With the help of highly accurate calibration of the sensor, 5 unique coefficients were stored on the chip, plus accurate pressure a temperature reading can be realized. BM02S is a low power, low voltage device with automatic power down switching. I2C serial interface is used for communications with microprocessor.
