RAK Wireless WisBlock Barometric Pressure Sensor
Overview
RAK1902 is a WisBlock sensor that expands the WisBlock system with a barometric pressure sensor. A ready-to-use SW library and tutorial make it easy to build a barometric pressure sensing system.
With a pressure range of 260 to 1260 hPa, the RAK1902 is suitable for use in weather forecast systems. The relative accuracy of ±0.1 hPa is sufficient for most applications.
Combined with the RAK4631 WisBlock Core, the RAK1902 is a ready-to-use system for collecting barometric pressure data. The collected data can be sent via LoRaWan® communication, LoRa® point-to-point connections and BLE.
The RAK1902 is ideal for battery-powered applications because of its low power consumption. In addition, the WisBlock system allows the module to be switched off completely to further reduce the system's power consumption.
The RAK1902 air pressure sensor can be connected to other WisBlock sensors such as a temperature and humidity sensor module to form a weather station.
