This soil sensor enables rapid acquisition of soil moisture and temperature data, ensuring optimal watering for plants in their growth environment. 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 and reliable output. Seamlessly integrate it with an Arduino UNO R3 and a TTL to RS485 expansion board to create a test environment efficiently.

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.

Probe Material - 316 Stainless Steel

Soil sensors are widely used in agricultural irrigation, greenhouses, flowers and vegetables, grassland and pastures, soil rapid testing, plant cultivation, 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.
