 It is able to report location, altitude, temperature and pressure to the internet (LoRaWAN networks such as Helium and TTN) or direct to another LoRa radio module with a solar panel/super capacitors or just 4xAAA batteries. 
 Because LightTracker is open source you can add your own custom sensors via I2C/SPI pins.
