✦Description of Soil PH Sensor

Soil over-acidity or over-alkalinity is an important factor that limits plant growth and quality. Most plants cannot tolerate over-acidity or over-alkalinity in soil. Therefore, it is very important to understand the PH and humidity of the soil. Soil PH sensor has high precision, fast response, stable output, and is suitable for all kinds of soil. It can be buried in the soil for a long time, is resistant to long-term electrolysis, corrosion, vacuum potting, and is completely waterproof. It can be widely used in soil PH detection, precision agriculture, forestry, geological exploration, plant cultivation, water conservancy, environmental protection and other fields of PH measurement.

✦The basic working principle of soil PH sensor

The hardware system with metal sensor as the core, the metal sensor is in contact with the soil, and the current generated by the oxidation-reduction reaction in the chemical reaction is used. The magnitude of the current value drives the unit data of different PH values ​​and humidity values ​​corresponding to the ammeter (no battery or other external power supply method is required).

✦Advantages of soil PH sensor

1- Vacuum filling, high airtightness of the sensor High-density epoxy resin is used for high-temperature vacuum filling between the probe and the body, which largely prevents moisture from entering the body and has better airtightness 2- IP68 protection level, waterproof and anti-corrosion, salt and alkali resistance Strict manufacturing process is used to waterproof and dustproof the entire body to ensure stable detection of components 3- The probe is made of high-quality austenitic 316 material Austenitic 316 stainless steel is used as raw material, which is rust-proof, non-electrolytic, resistant to salt and alkali corrosion, and suitable for various soil types 4- Imported low-power MCU high-quality op amps are used inside the sensor to ensure low power consumption, high sensitivity, and stable signal transmission of the sensor 5- Support secondary development, standard ModBus-RTU communication protocol, support KingView, Sanwei Force Control, MCGS Kunlun Tongti configuration software configuration screen, PLC, and user-developed platform

✦There are two ways to use the soil PH sensor

– Rapid measurement method: Choose a suitable measurement location, avoid stones and similar hard objects, dig up the surface soil according to the required measurement depth, keep the original looseness of the soil below, hold the sensor tightly, and insert it vertically into the soil. Do not shake it left and right when inserting it. It is recommended to average multiple times within a small range of a measurement point. – Buried measurement method Vertically dig a pit with a diameter of about 20cm, the depth is based on the measurement requirements, insert the sensor steel needle horizontally into the pit, fill and compact the pit, ensure that the steel needle is in close contact with the soil, and after the sensor stabilizes for a period of time, it can be continuously measured and recorded for a long time.
