Abstract

The invention discloses a soil temperature, moisture and conductivity measuring device which mainly comprises a sensor unit, a data acquisition and processing unit and an MCU. The sensor unit mainly comprises a soil temperature sensor, a soil moisture sensor and a soil conductivity sensor. The data acquisition and processing unit mainly comprises a voltage conversion circuit, a signal generating circuit, a signal processing circuit, an analog-to-digital conversion circuit and a 485 communication circuit. The device is a detection device which integrates soil temperature, soil moisture and soil conductivity measurement. A wiring end is arranged on one end of each sensor. Each wiring end consists of three probes, namely left, middle and right probes. The positions of three probes are parallel to each other. A trigeminal probe structure is used, and each sensor can be conveniently and rapidly implanted into the soil and fixed. The device has the advantages of simple structure and low cost, can simultaneously measure the moisture, temperature and conductivity in the soil. The measurement time of the temperature, moisture and conductivity of the soil is shortened. The measurement efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a device for measuring soil temperature, moisture and electrical conductivity. Background technique [0002] Soil temperature refers to the temperature in the soil below the ground, mainly referring to the temperature of the shallow layer under the ground directly related to plant development. Soil temperature affects the growth and development of plants and the formation of soil. Various biochemical processes in soil, such as biochemical processes and non-chemical processes caused by biological activities, are all affected by soil temperature. Too high or too low temperature will make plants grow damaged. [0003] Soil water is the main source of water absorption by plants (except for hydroponic plants), and plant cultivation is inseparable from the measurement of soil moisture. There are four types of soil moisture, and their effectiveness varies: ①Hygroscopic water, t...
