Cat1(4g) Temperature And Humidity Wireless Monitoring System

 箭头  Background

       From the second half of 2020, under the condition that the coverage of 4G/5G mobile communication base stations is relatively complete, operators will gradually suspend the access of 2G terminals to the network. China Unicom, Telecom began to terminate the service of 2G base station. Several major operators have put their energy on emerging new mobile IoT technologies such as CAT1 and NB. Among them, CAT1 is a low-speed 4G Internet of Things solution, which can use the existing mobile base station, without the need to build a new mobile network base station, and can perfectly replace the existing GPRS communication module.

 箭头  Function

         ⚪  It can monitor the temperature and humidity of various environments in real time.

         ⚪  The networking is convenient and fast.

         ⚪  Support cloud platform, display real-time temperature and humidity data, and save historical data.

         ⚪  The platform realizes multi-user management.

 箭头  System Composition

      The System Consists Of Three Parts: Wireless Transmission, Temperature And Humidity Sensor, And Cloud Platform.

          ⚪  Wireless Transmission

                      The wireless transmission technology uses a combination of LORA, 2G/3G/4G/5G/CAT1 (mobile network) and Ethernet. Use LORA locally to transmit sensor data to the gateway, which in turn transmits the data to the platform via a mobile network or Ethernet. Wireless transmission adopts a variety of technologies to ensure the convenience of networking, long transmission distance and low power consumption.

          ⚪  Temperature And Humidity Sensor

                       For different temperature measurement scenarios, our company has developed a variety of temperature and humidity, temperature sensors. Our temperature measurement sensors are divided into ordinary places, high humidity places, and non-contact rapid temperature measurement. The temperature and humidity sensors in ordinary places are made of imported materials and use our company's dedicated temperature and humidity calibration algorithm, which can accurately detect the temperature and humidity of the monitored places. The temperature and humidity sensors in high-humidity places are adapted to work in high-humidity environments. General temperature and humidity sensors cannot work in high-humidity environments for a long time. Our company uses advanced production technology and long-term soaking tests. Work in a high humidity environment. The non-contact temperature sensor uses the principle of infrared optical technology to detect the temperature of the measured object by detecting the infrared wavelength of the measured object.

          ⚪  Cloud Platform

                       The cloud platform provides powerful device management capabilities and data processing capabilities. The cloud platform can manage the equipment in real time, and maintain the equipment status, installation information and location information in a unified manner. The powerful data processing capability of the platform can display, save and analyze the data uploaded by the device.
