Monitoring Solutions for Water, Indoor, Outdoor, & Agriculture
The sensor provides accurate measurements using the field-tested ECH2O sensor. It features a high-frequency (70 MHz) design for good accuracy, even in high-salinity and sandy soils.
The sensor provides accurate measurements using the field-tested ECH2O sensor. It features a high-frequency (70 MHz) design for good accuracy, even in high-salinity and sandy soils.
This wireless soil moisture sensor is ideal for most soil monitoring and research. The ECH₂O EC5 sensor has the ability to measure in volumetric water content in labs or greenhouses. With the compatibility to the HOBOnet Wireless Sensor Network, the measured data from the sensor are transmitted across the network to the central station to the HOBOlink web-based software where you can monitor sensor readings, view graphs, set up alarms, download data, and more.
