WisBlock Barometric Pressure Sensor | RAK1902

Description

RAK1902 is a WisBlock Sensor based on the STMicroelectronics LPS22HB chip which extends the WisBlock system with barometric pressure sensing capabilities. A ready-to-use SW library and tutorial make it easy to build up a barometric pressure data acquisition system.

RAK1902’s pressure range from 260 to 1260 hPa makes it suitable for use in weather prediction systems The relative accuracy of ±0.1 hPa is su­cient for most applications.

RAK1902 combined with the RAK4631 WisBlock Core is a ready-to-go system to collect barometric pressure data. The acquired data can be sent using LoRaWan® communication, LoRa® point to point connections and BLE.

RAK1902 is ideal for battery-powered applications because of its low power consumption. In addition, the WisBlock system allows to power down the module completely to reduce the power consumption of the system even more.

RAK1902 barometric pressure sensors can be joined with other WisBlock sensors like a temperature and humidity sensor module to create a weather station.
