RAK1901: WisBlock Temperature and Humidity Sensor

RAK1901 is a WisBlock sensor that extends the WisBlock system with a temperature and humidity sensor. A ready-to-use SW library and tutorial facilitate the creation of an ambient temperature and humidity data acquisition system. The RAK1901's temperature range of -40 to +125 °C allows its use in almost any environment. The temperature accuracy of ± 2.0 °C is sufficient for most applications. RAK1901 combined with RAK4631 WisBlock Core is a ready-to-use system for collecting environmental data. Acquired data can be sent using LoRaWan® communication, LoRa® point-to-point connections, and BLE.

RAK1901 is ideal for battery-powered applications due to its low power consumption. Furthermore, the WisBlock system allows the complete module to be shut down to further reduce the system's power consumption. The RAK1901 temperature and humidity sensor can be combined with other WisBlock sensors such as a barometric pressure sensor module to create a weather station.
