QT-SM101 Soil moisture temperature meter

Product description: QT-SM101 is based on TDR (Time domain Reflectometry) technology, it can be used to rapidly measure the moisture of various types of soils. By measuring the dielectric constant of soil or other media, the meter can calculate soil water content, because soil water content is closely related to the dielectric constant. Soil temperature is measured via high-precision thermistor. Soil moisture and temperature data can be transmitted to a handheld Android terminal by WIFI.
