Product description: QT-ML3 portable soil moisture/temperature meter can be used for the measurement of moisture of various types of soil and media, and it can be used as a basic tool for on-site observation or mobile measurement.
QT-ML3 Portable soil moisture/temperature meter
Principle
Using FDR (frequency domain reflectometry) principle, the sensor emits electromagnetic wave with a certain frequency, the waves transmit along the probe till they reach the bottom of the probe and return to the sensor, the output voltage is recorded. Because the dielectric constant of the soil usually depends on the soil moisture, the soil water content can be calculated according to the relationship between the output voltage and soil moisture.

Product description: QT-SM100 soil moisture meter 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 moisture data can be transmitted to a handheld Android terminal by WIFI.

I'm selling my SHARP CV-10MH 10000 BTU Portable Air Conditioner. It works perfectly fine, I just don't have space for it anymore. I do not have the remote for it. Really great deal for a 10,000 BTU Air Conditioner that is in working order. I will throw in the extension hose also, I use to use it to get the hot air exhaust all the way out the window.
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.
