Piezoresistive absolute pressure sensor
max. 1 100 hpa | BM03S
Celmi
The BM03S includes a piezo-resisteve pressure sensor and an ADC interface. It provides 16bit word data for pressure and temperature related voltage. With the help of a highly accurate calibration of the sensor, 11 unique coefficients were stored on the chip, thus accurate pressure and temperature reading can be interface is used for communications with a microprocessor. Sensor packaging options are DIP or SMD (with metal cap).
