Editorial narrative

Product Description RAK1901 is a WisBlock Sensor based on Sensirion SHTC3 which extends the WisBlock system with temperature and humidity sensing capabilities . A ready to use SW library and tutorial makes it easy to build up an environmental temperature and humidity data acquisition system. RAK1901's temperature range from -40 to +125 °C enables its use in nearly any environment. The temperature accuracy of ±2.0 °C is su­cient for most applications RAK1901 combined with the RAK4631 WisBlock Core is ready to go system to collect environment data. The acquired data can be send using LoRaWan® communication, LoRa® point to point connections and BLE. RAK1901 is ideal for battery-powered applications because of its low power consumption. In addition, the WisBlock system allows to power down the module complete to reduce the power consumption of the system even more. RAK1901 temperature and humidity sensor can be joined with other WisBlock sensors like a barometric pressure sensor module to create a weather station.
