Internet-of-things wireless plant root system soil layered measurement sensor

Abstract

The invention discloses an Internet-of-things wireless plant root system soil layering measurement sensor. The sensor comprises an antenna, a rod head, a lock catch and a straight rod. The straight rod is electrically connected with the rod head through the lock catch, the antenna is arranged above the rod head, the wireless transmission is carried out through the antenna to upload data to a cloudInternet-of-things management platform, an A / D converter and a solar panel are arranged in the rod head, and n scale marks are engraved on the surface of the straight rod, and a group of temperature,moisture and EC value sensors are arranged on an inner side of each scale mark. The A / D converter in the rod head is electrically connected with each group of temperature, moisture and EC value sensors to receive temperature, humidity and EC values.

Description

technical field [0001] The invention relates to the technical field of soil analysis, in particular to an Internet of Things wireless plant root soil stratification measurement sensor. Background technique [0002] The acquisition of soil stratification parameters is the front-end basis for soil water cycle research, irrigation management, efficient use of water resources, and soluble ion concentration. Fertilization, so that irrigation water and fertilizer can be effectively used, so as to achieve the purpose of weight loss, water saving and high crop yield. [0003] High concentrations of soluble salts can damage plants or cause the death of plant roots, which will seriously affect the growth of crops and lead to crop yield reduction. A stable, reliable, universal and extensible soil stratification parameter acquisition solution will help improve the environmental monitoring level of precision agriculture. [0004] By deploying the Internet of Things plant root soil laye...

Problems solved by technology

[0005] The existing patent CN201721066952 is a low-power four-in-one sensor. Although it can measure soil temperature, humidity, illuminance, and EC values, it needs to install multiple sets of four-in-one sensors to measure the temperature, humidity, and EC values ​​​​of soil layers at different depths. One sensor (if you want to measure the temperature, humidity, EC value and other parameters of the soil layer with a depth of 15cm, 45cm, and 90cm respectively, you need to dig holes three times and embed 3 sets of four-in-one sensors, and the illuminance cannot be achieved after being embedded in the soil layer. Detection function, after the sensor antenna is buried in the ground, the function of wireless data transmission cannot be realized, and the data can only be transmitted by wired transmission. Using a 3v button battery, the continuous transmission of data cannot be achieved, and the battery needs to be replaced; most of the soil is stratified at present. The installation of the measurement sensor is troublesome, there is no elevation, and the buried depth of the sensor needs to be measured on site; the cost of use is high, and each set of sensors requires an independent microprocessor, power supply, wireless transmission system, etc., which makes it impossible to be widely used in agricultural production; there is no positioning function ; It is necessary to dig holes for multiple times to bury the sensor, which is labor-intensive and low-efficiency
