WisBlock RAK1902 Barometric Pressure Sensor

The RAK1902 WisBlock Barometer pressure sensor is a compact sensor module with an I2C interface that measures absolute pressure and temperature values. Its measurement range for pressure is 260-1260 hPa and for temperature is -40 to 85°C. The accuracy is ±0.1 hPa for pressure and ±1.5°C for temperature. The WisBlock ecosystem by RAK Wireless provides compact and modular solutions to create your own IoT-LoRaWAN nodes. Various CPU, sensor, and IO extension modules can be mounted on a WisBlock base board. Unlike conventional connectors, the modules are fixed to the base board with screws. This provides a secure and reliable attachment with industrial quality. Thanks to its modular and compact design, WisBlock is particularly suitable for applications in professional or hobby prototype construction.
