Application of PT100 Temperature Sensor in the Internet of Things

I. Overview:

NB-IoT wireless sensor is a wireless temperature smart meter equipped with NB-IoT module. Adapt to PT100 temperature sensor. It is an ideal low-power intelligent instrument for temperature acquisition, transmission and display. It is suitable for smart city application scenarios such as oil field, water conservancy, fire pipe network, water pipe network, urban heating pipe network, etc. It is a wireless pressure, temperature, temperature and pressure integrated smart meter equipped with NB-IoT module. Compatible with diffused silicon sensor and PT100 temperature sensor. It is an ideal low-power intelligent instrument for pressure, temperature acquisition, transmission and display. It is suitable for smart city application scenarios such as oil field, water conservancy, fire protection pipeline network, tap water pipeline network, and urban heating pipeline network.

Ⅱ. Features:

1. Sampling low-power microprocessor, NB-IoT wireless communication technology, battery-powered, low-power operation, battery life of 2-5 years (affected by the upload interval).

2. There is no need for gateway routing RTU and other equipment, the data is directly connected to the background server, and the installation is simple;

3. Support data access services of third-party platforms, suitable for oil fields, tap water, mines, and water conservancy. Internal parameter settings are more suitable for group users.

4. Strong anti-interference characteristics, the temperature characteristics of the whole machine are very good, and the working temperature range is -30-70 degrees.

5. High protection level above IP65, suitable for outdoor occasions.

6. A variety of application software and hardware support, data transmission solutions, customer application software and hardware support.

Ⅲ. System composition

The instrument is responsible for collecting sensor information such as pressure, liquid level, and temperature, and uploading data to the cloud platform through the NB-IoT network at preset intervals.

2.cloud platform:

The cloud platform is responsible for collecting and saving data uploaded by sensors, has a complete and rigorous background protocol, and can handle certain business logic. The cloud platform can be a private cloud, an IoT cloud platform, and a third-party data platform.

3.Application development support:

Provide a concise API interface, through which the client web, PC, Android APP and other application programs can be developed quickly, helping customers to quickly realize the Internet of Things data access and data analysis capabilities.
