Product introduction
The low-cost soil temperature and humidity sensor MSE (Minyuan Soil Economical) is a smart sensor with capacitive high-frequency dielectric constant measurement and non-contact sensing, suitable for detecting soil moisture content and temperature. The sensor embeds a high-precision digital capacitance sensing chip, microprocessor, and algorithms. The moisture content % is proportional to the capacitance value, which can be fitted and converted from the capacitance value according to different soil characteristics. Based on the UART MODBUS communication protocol, the sensor firmware and algorithms can be upgraded online.
