【Product description】
IOT-S300SMT soil temperature and humidity sensor is a combination of soil moisture and soil temperature sensors to facilitate the measurement and research of soil moisture and soil temperature. The product has high precision, fast response and stable output. It is less affected by the salt content of the soil and is suitable for various soil qualities. Can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, waterproof and rust-proof.
【Features】
● Small size design, easy to carry, simple installation, operation and maintenance
● Good airtightness, can be buried in different depths of soil for a long time
● High measurement accuracy and reliable performance
● Fast response speed and high data transmission efficiency
【Scope of application】
● Water-saving agricultural irrigation, weather monitoring
● Greenhouses, flowers and vegetables, grass pastures, soil testing
● Fields that need to measure soil moisture, such as plant cultivation and scientific experiments
