MX2307A HOBO MX Soil EC/VWC/Temp Data Logger
Integrated Bluetooth logger for soil moisture/VWC, EC, temperature, and relative humidity with TEROS 10 sensor.
The HOBO MX2307A is an integrated Bluetooth logger for monitoring soil, plant, and atmospheric conditions. It measures soil moisture/VWC, soil electrical conductivity, and temperature through an external sensor, plus temperature and relative humidity through the internal sensor.
It is designed for researchers and growers who need accurate data to assess growing conditions, improve yields, reduce harmful runoff, and protect ecosystems. It includes pre-attached sensors and a TEROS 10 soil moisture sensor with a field life of over 10 years, suitable for mineral soils and soilless media.
Wireless setup and data download are performed through Bluetooth and the free HOBOconnect app on a phone, tablet, or Windows computer, up to 100 ft away. For remote greenhouse access it can be combined with an MX Gateway and MX Data Plan for LI-COR Cloud. Data can be viewed as Percent of Field Capacity.
