This is the LPS22HH a High-performance MEMS (Microelectromechanical ) nano pressure sensor that ranges to 260 – 1260 hPa (Hectopascal) an absolute digital output barometer that communicates through 3 protocols i2C, i3C, and SPI. from sensing elements, which detects an absolute pressure that consists of a suspended membrane design for dedicated approach. The LPS22H was developed by STMicroelectronics and can operate at a temperature level of -40 degrees to +85 degrees suited for the harsh environment. These LPS22HH are suitable for numerous applications such as weather types of equipment, or perhaps weather station devices, GPS Devices, Wearable devices, Drones, Gas metering, or altimeters and barometers for portable devices. For more technical details and specifications such as communicating with SPI or i3C refer to the datasheet below. Moreover, our source code below demonstrates using the i2C protocol and some minimal wiring requirements.
