The wireless soil temperature and humidity monitoring unit launched by Weichuan Technology is mainly used for soil temperature and humidity measurement. Using German original high-precision sensors and soil actual drying weighing method calibration, it has high accuracy, fast response, stable output, and is less affected by soil salt content, making it suitable for various soil types. Can be buried in soil for a long time, resistant to long-term electrolysis, corrosion-resistant, vacuum sealed, completely waterproof. The data transmission adopts LoRa technology, which has the characteristics of long distance and low power consumption. Widely applicable to scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grassland pastures, soil rapid testing, plant cultivation, sewage treatment, grain storage and other scenarios.
