CJMCU-22 LPS22HB Barometric Pressure Sensor
LPS22HB is an ultra-compact piezoresistive absolute pressure sensor that functions as a digital output barometer. The device includes a sensing element and an IC interface that communicates from the sensing element to the application via I2C or SPI. It is guaranteed to operate in a temperature range from -40 °C to +85 °C. The package is perforated to allow external pressure to reach the sensing element.
Features:
- Absolute pressure range from 260 to 1260 hPa
- Low current consumption up to 3 μA
- High overpressure capability: 20x full scale
- Embedded temperature compensation
- 24 bit pressure data output
- 16 bit temperature data output
- ODR from 1 Hz to 75 Hz
- SPI and I²C interfaces
- Embedded FIFO
- Interrupt functions: Data Ready, FIFO flags, pressure thresholds
- Supply voltage: 1.7 - 3.6 V
