RAK1903 is a WisBlock Sensor which extends the WisBlock system with an ambient light sensor. A ready to use SW library and tutorial makes it easy to build up an ambient light data acquisition system.

RAK1903's range from 0.01 lux to 83865 lux makes it suitable for a greenhouse control system, light detection system, or alarm systems.

RAK1904 is a WisBlock Sensor which extends the WisBlock system with an acceleration sensor. A ready to use SW library and tutorial makes it easy to build up motion data acquisition system.

RAK1904's scale from ±2g to ±16g can be adjusted to the requirements of your application. Depending on the application the data rates can be adjusted from 1Hz to 5.3kHz.

RAK1904 combined with the RAK4631 WisBlock Core is ready to go system for a motion tracking system, detecting and monitor vibrations in rotating machinery or even to monitor active volcanoes. The acquired data can be send using LoRaWan® communication, LoRa® point to point connections and BLE.

RAK1904 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.

RAK1904 acceleration sensor can be joined with other WisBlock sensors like a GPS module to create an inertial navigation system.
