Smart water temperature monitoring

I. Background

As living standards continue to rise, hot spring wellness has come into the public eye. In the context of hot spring therapy, water temperature is a crucial factor; however, research on monitoring hot spring temperatures remains relatively limited.

Staff can only rely on their personal experience to manually or semi‑automatically regulate the temperature of the hot spring water, making it impossible to maintain precise temperature control at all times.

 

What temperature of hot spring is best? Hot springs at different temperatures offer distinct therapeutic benefits.

Hot springs with temperatures exceeding 75°C are classified as high-temperature hot springs.

40℃ to 75℃ is classified as a moderate-temperature hot spring.

Temperatures below 40°C are classified as low-temperature hot springs.

Below 25°C is a cold spring.

 

II. Function Implementation

Therefore, to better manage hot spring water temperatures and enhance service quality and user experience, remote monitoring of hot spring water temperature has become an essential solution. This paper presents an intelligent solution for detecting hot spring water temperature.

By integrating a water‑temperature sensor, wireless transmission technology, and a remote display screen, real-time monitoring and remote observation of hot‑spring water temperature can be achieved. The following is the system block diagram.

 

III. Product Introduction

1. Water temperature sensor

The water temperature sensor is one of the key components in a hot spring water‑temperature monitoring solution. By installing the sensor in the hot spring pool, changes in water temperature can be monitored accurately and in real time. The sensor should feature high precision,

It possesses properties such as high-temperature resistance and corrosion resistance to meet the demands of hot spring environments and ensure the reliability and accuracy of monitoring data.
