Soil temperature, humidity and conductivity detection system

A soil temperature, humidity and conductivity detection system disclosed by the invention comprises a host device, slave devices and an upper computer, wherein the slave devices are used for collecting temperature, humidity and conductivity information at distribution points, the host device is used for transmitting the received information collected by the slave devices to the upper computer, and the host device communicates with the slave devices in a mesh networking mode. According to the soil temperature, humidity and conductivity detection system, manual acquisition of soil temperature, humidity and conductivity data can be reduced; a plurality of monitoring points can regularly send data to the host in a cross-distance manner, and the data can be wirelessly transmitted to the Ali cloud for data storage management; after the upper computer receives the data, the data of each monitoring point can be well obtained, so that the implementation of subsequent accurate regulation and control is facilitated, and
