The Chameleon Wi-Fi System contains a Chameleon Wi-Fi Reader plus a three-sensor array on a plug with a temperature sensor and unique ID. The Reader displays colours, stores data and sends data to the VIA platform when there is access to Wi-Fi or a mobile phone hotspot.

The Wi-Fi Reader has three LED coloured lights that shows the water status at three depths in the rootzone. Once a user understands the meaning of the three LED coloured lights, they can regularly monitor and then irrigate when needed.


  • The Wi-Fi Reader stores and sends data to the VIA platform to create a unique colour pattern for each crop.
  • By comparing many patterns and their associated yields, it is possible to explore ways to save more water and get higher yields
