Highlights
- The most common type of technology used in standard moisture sensors is electrical conductivity (EC). We’ve found the accuracy of standard sensors to be unreliable (an accuracy of about ~15%). This unreliability stems from a number of problems:
- Soil salinity: EC-based moisture sensors can be affected by the salt in the soil, which can interfere with the accuracy of the readings.
- Soil compaction: If the soil around the sensor becomes compacted, it can affect the ability of the sensor to accurately measure moisture levels.
- Sensor drift: Over time, EC-based moisture sensors can experience drift, which means that the readings become less accurate over time.
- Sensor placement: The accuracy of EC-based moisture sensors can be affected by the placement of the sensor in the soil.
