Overview
Hospitality Enviro Tech advanced Lora node sensor with long-range communication has a small size and integration characteristics. It is convenient to transport, carry and install, and can be dynamically adjusted at any time. The appearance, working conditions, safety requirements, functional requirements, and communication requirements of the equipment can be adapted to different measurement environments.
The sensor is suitable for measuring soil temperature, moisture, total soil salt (conductivity), soil PH, nitrogen, phosphorus, potassium, and other parameters, which greatly facilitates the evaluation of soil conditions by the customer system.
The product network transmission adopts a stable and reliable operator network, mature technology, stable transmission, strong signal, and wide coverage. At the same time, the device supports regular data collection and active uploading to the server platform.
It is widely used in scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grassland pastures, soil rapid testing, plant culture, sewage treatment, grain storage, and measurement of water content and temperature of various particulate matter.
