The LPS22HB is an ultra-compact piezoresistive absolute pressure sensor which functions as a digital output barometer. The device comprises a sensing elementsand an IC interface which communicates through I2C or SPI from the sensing elementsto the application. The sensing element, which detects absolute pressure, consists of a suspended membrane manufactured using a dedicated process. The LPS22HB is available in a full-mold, holed LGA package (HLGA). It is guaranteed to operate over a temperature range extending from -40 Celsius to +8 Celsius.The package is holed to allow external pressure to reach the sensing element. 260 to 1260hPa absolute pressure range Current consumption down to 3uA High overpressure capability: 20x full-scale Embedded temperature compensation 24-bit pressure data output 16-bit temperature data output ODR from 1Hz to 75Hz SPI and I2C interfaces Embedded Interrupt functions: Data Ready, flags,pressure thresholds Parameter: Work Voltage:DC 3.3V Protocol:IIC/SPI Work Temperature:-40 Celsius~125 Celsius Work Humidity:0%~95%RH Colour: purple Material: PC + metal Size: 21*11.7*2.6mm Package Contents: 1 x LPS22HB Pressure Resistance Pressure Sensor Module 1 x 8Pin 2.54mm male pin Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
