1. Product Introduction

The self-recording water thermometer and RTU integrate advanced technologies such as water temperature sensing, IoT, and wireless data transmission. It is easy to install and use, powered by solar panels and batteries, eliminating the need for mains electricity and wiring. Simply fix the sensor and data processing unit to start operation, and real-time data can be viewed on any WEB terminal. Data can be collected at frequencies requested by the customer, with high accuracy and excellent system stability.

2. System Features

(1) Default collection of water temperature with a sampling frequency of 1 hour, adjustable according to customer requirements. The collection system integrates channels for voltage, current, and 485 communication.

(2) Simple installation and convenient maintenance. Consists of two parts: the collection unit and the sensor unit, which can be used after fixation. During operation, minimal manual maintenance is required; data can be viewed on the network platform.

(3) Users can access real-time data from monitoring stations via various terminals such as PCs, iPads, and smartphones at any time.

(4) Aesthetically pleasing design, corrosion-resistant, and interference-resistant.

(5) The water temperature sensor and collection unit communicate wirelessly via 4G, allowing flexible placement without distance limitations.
