How Soil Moisture Sensor Works
This article is mainly based on the introduction of soil moisture sensor and the working principle of soil moisture sensor. Here we will discuss the introduction of soil moisture sensors, their characteristics, working principles and applications.
A Soil Moisture Sensor is one kind of low-cost electronic sensor that is used to detect the moisture of the soil. This sensor can measure the volumetric content of water inside the soil. This sensor is consists of mainly two parts, one is Sensing Probs and another one is the Sensor Module. The probes allow the current to pass through the soil and then it gets the resistance value according to moisture value in soil. The Sensor Module reads data from the sensor probes and processes the data and converts it into a digital/analog output. So, the Soil Moisture Sensor can provide both types of output Digital output (DO) and Analog output(AO).
JXCT soil moisture sensor adopts the international new generation FDR measurement method, which can reach an accuracy of less than 3%; the electromagnetic non-contact measurement method, the soil sensor will not drift with time, which greatly enhances the stability of the product and extends the service life.
(1)High protection performance: High-density epoxy resin is used for high-temperature vacuum filling between the probe and the body, which can prevent moisture from entering the inside of the body and has a better sealing performance. In addition to the combined part, we also do waterproof and dustproof treatment to the entire body to ensure long-term operation of the components.
(2)Probe: We use austenitic 316 stainless steel as the raw material for the probe part, which is anti-rust, electrolytic, and salt-alkali corrosion resistant, ensuring the long-term operation of the probe part. Therefore, it is suitable for all kinds of soil.
(3)Internal structure: low power consumption and high sensitivity chip, the soil sensor uses imported high quality chip inside, low power consumption, high sensitivity and stable signal.
Soil sensor is suitable for farmland production, soil research, greenhouse planting, orchard nursery, all kinds of horticultural soil testing, support parameter free customization, multi in one soil sensor customization.
