This soil sensor facilitates rapid acquisition of soil temperature, moisture, and electrical conductivity (EC) data, ensuring precise irrigation for optimal plant growth. It supports a wide voltage power supply range of 5-30V and communicates data via RS485 using the reliable MODBUS-RTU protocol. The sensor exhibits quick response times and delivers stable, reliable output. Seamlessly integrate it with an Arduino UNO R3 and a TTL to RS485 expansion board to efficiently create a test environment.

The protection level of the soil sensor is IP68, and it is vacuum-filled and sealed with black flame-retardant epoxy resin. The probe material is made of 316 stainless steel, which is rust-proof, waterproof, anti-corrosion, salt-alkali corrosion resistance, and long-term electrolysis resistance. It is more affected by the soil salt content. It is small, can be buried in the soil for a long time, and is suitable for various soil types.

The soil sensor has an automatic temperature compensation function for conductivity, which ensures measurement accuracy no matter how the environment changes.

It is widely used in agricultural irrigation, greenhouses, flowers and vegetables, grassland and pastures, soil rapid testing, plant culture, scientific experiments, grain storage and the measurement of moisture content and temperature of various particulate matter.

Soil temperature has a direct impact on plant growth. Proper soil temperatures help promote plant root growth and the ability to absorb nutrients. Generally speaking, higher soil temperature is helpful for plant growth because it can increase plant metabolism, promote nutrient absorption and transport, and increase plant microbial synthesis capabilities, thereby promoting plant growth rate and yield.

In addition, appropriate soil moisture helps plant roots absorb water and nutrients and maintains water balance within plant cells. If the soil moisture is too low, plant roots will be limited in absorbing water, which can lead to plant dehydration, stagnant growth or even death. Excessive soil moisture may cause hypoxia in plant roots, hinder normal respiration and nutrient absorption of roots, and thus affect plant growth and development.

Soil electrical conductivity (EC) is the level of salt in the soil (salinity). These parameters are important indicators of soil fertility and health, and ultimately affect plants. When soil has high salt content, the salt makes it difficult for plants to absorb water, even if the moisture content in the soil is high. This condition will eventually "burn" the plant. Plants grow best in their preferred environment within the optimal range of soil moisture, temperature and EC levels. Growers need data on these parameters and understand what actions need to be taken to ensure plant health and higher yields.
