Chameleon Sensors is centered around a soil moisture sensor system designed to help farmers optimize irrigation. The technology was developed through a project funded by the Australian Centre for International Agricultural Research (ACIAR) and supported by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). The system aims to be an inexpensive, easy-to-install, and simple-to-understand tool, particularly for smallholder farmers in developing regions. The core product is the Chameleon Soil Water Sensor, which measures soil tension to determine how difficult it is for plant roots to extract moisture.
This method allows the sensor to be effective across different soil types without needing calibration. The sensor system consists of a resistivity sensor buried in the soil and a reader that displays the data through a simple, color-coded light interface: blue indicates wet soil, green signifies moist soil, and red means the soil is dry and irrigation is needed. This visual feedback helps farmers easily decide when and how much to irrigate, preventing both under-watering and over-watering. Sensor arrays are typically installed at multiple depths to provide a comprehensive view of the root zone.
The system includes several components: the sensor arrays, a handheld Chameleon Card for reading single sensors, and a Chameleon Wi-Fi Reader that can read an array of three sensors, store the data, and upload it to the via.farm website when an internet connection is available. Data can also be logged on a mobile app. The B2B model involves the sale of the sensor kits, which include a reader, sensor array, and charging cable, through distributors like the Virtual Irrigation Academy (VIA) Shop, which is overseen by CSIRO.
By using the sensors, farmers have reportedly increased crop yields by up to 30% and reduced water consumption by a similar margin.
