Liber Probe - Better Urban Agriculture

Liber, Roman God of fertility. This project uses infrared technology to measure humidity in soil samples, processes the data, and displays the humidity status of the soil samples. Liber has two modules, the Control module, and the Probe module. Liber Probe has integrated IR LED sensors, detecting wavelengths of around 1450 nanometers, which is where water absorption is detected in the IR spectrum. This data is processed through the integrated microprocessor and transmitted using Bluetooth Low Battery transmitters. This data is recieved in the Liber Control module, combined with the data of other Probes, and displayed on screen.
