Abstract

The invention discloses a soil parameter sensor based on NB-IoT. The sensor comprises an electrode module, a signal module, a main control module, a communication module and a power supply module; the electrode module comprises a plurality of electrodes; the signal module is used for generating and processing signals required by soil parameter detection; the main control module is used for processing data at least from the signals; the communication module comprises an NB-IoT chip; the power supply module comprises a lithium ion battery; the electrode module is electrically connected with the signal module, so that the electrode can transmit or receive an electromagnetic signal generated by the signal module; the signal module, the communication module and the power supply module are electrically connected to the main control module. The soil parameter sensor based on the NB-IoT has the advantages of better power supply and communication performance.

Description

technical field [0001] This application relates to the field of soil detection, in particular to a soil parameter sensor based on NB-IoT. Background technique [0002] Soil moisture refers to the moisture content of the soil. Soil moisture is the degree of dryness and wetness of the soil, that is, the actual water content of the soil, which can be expressed by the ratio of soil water to dry soil weight or soil volume, or the percentage of soil water content equivalent to the field water holding capacity, or relative to the saturated water content. Expressed in relative quantities such as percentages. Existing soil moisture and other parameter detection devices generally use corresponding detection heads with probes or other detection elements to be inserted into the soil for detection. Moreover, the existing soil moisture detection devices all need to use wired power supply or wired power transmission to work. [0003] This is very unfavorable to the detection environment...
