Chameleon Card

The Chameleon Card is the simplest way to measure a Chameleon sensor. It measures one sensor at a time, but does not store or upload data.

Six pack of single Chameleon Soil Water Sensors

How it works

  1. Chameleon Soil Water Sensors are buried in the root zone.
  2. The 2m wire is left above ground.
  3. The farmer touches the wires to the Chameleon Card and holds in the switch.
  4. The Chameleon Card instantly measure the soil water and displays the value using a coloured LED.
