1. System Overview

This system is a wireless remote temperature‑monitoring solution based on the PT1000 high‑precision temperature sensor. Powered by batteries, it leverages LoRa, LoRaWAN, and Cat1 wireless communication technologies to transmit temperature data.

Data is uploaded in real time to a cloud platform or an on-premises server, making it suitable for demanding industrial environments such as power equipment monitoring, oil pipeline surveillance, and mine‑site monitoring. The system block diagram is shown below:

2. System Composition

This system comprises a PT100 temperature probe, wireless transmission, a gateway, a cloud platform, and a mobile app.

The front-end sensor is a high-performance, high-precision, and highly sensitive temperature data acquisition device. It accepts PT100/PT1000 resistance temperature detector signals at the front end and converts them into temperature data via LoRa/

LoRaWAN and Cat1 communication enables direct connectivity with gateways or cloud platforms, offering fast data transmission and convenient data acquisition, thereby facilitating network deployment in engineering projects and industrial applications.

This system supports wireless data transmission via three standards: LoRa/LoRaWAN, CAT‑1, and Wi‑Fi. LoRa/LoRaWAN is well suited for applications with stringent power‑consumption requirements, such as deploying sensors across a large industrial site.

A centralized management solution. Wi‑Fi is deployed throughout the plant area, suitable for locations with low power‑consumption requirements. Cat (4G) is ideal for more dispersed deployments where 4G network coverage is available.

For applications with modest power‑consumption requirements.

Feature Introduction

A LoRaWAN gateway is an IoT‑grade gateway router based on the low‑power, wide‑area LoRaWAN protocol, providing IoT devices with low‑power, mobile, and secure local two‑way wireless connectivity.

Communication services supporting multiple wireless communication protocols, including LoRa, 2G/3G/4G/5G, and Wi‑Fi. The LoRaWAN gateway employs a star‑topology architecture, with front‑end node devices transmitting in a single hop to one or multiple LoRaWAN gateways.

It enables wireless communication between terminal devices and cloud servers, and can also connect to the cloud via standard IP. It is widely used in smart cities, smart communities, smart campuses, smart oilfields, and the smart tobacco industry.
