Description

Overview

GAOTek 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.

 

Features:

  • Transmission distance: 1Km in towns and 3Km in suburbs
  • Operating frequency: ISM frequency band includes 470 MHZ to 510 MHZ, etc.
  • Standard: IEEE 802.15.4g
  • Modulation method: based on spread spectrum technology,
  • Capacity: One gateway can connect thousands of LoRa nodes
  • Security: AES128 encryption
  • Transmission rate: hundreds to tens of Kbps, the lower the rate, the longer the transmission distance
