In modern pool management, water temperature monitoring is a key factor in ensuring user comfort and water quality safety. In order to achieve efficient and accurate pool temperature measurement, it is particularly important to develop a temperature meter with integrated Wi-Fi function. This article will discuss how to choose the right Wi-Fi 5GHz chip and how to design and implement this device.


1. The Importance of Temperature Measurement

The water temperature of the pool directly affects the swimming experience. The right water temperature not only improves comfort, but also inhibits bacterial growth and maintains water quality. Therefore, developing an efficient temperature meter or a wireless digital pool thermometer that can monitor and adjust the pool water temperature in real time is an important measure to ensure the health of the pool environment.


2. Choose the right Wi-Fi 5GHz chip

Digital pool thermometers are basically used in modern pool designs. When designing a pool temperature meter, it is key to choose a chip that supports 5GHz Wi-Fi. The 5GHz band has less interference and faster transmission speed than the 2.4GHz band, which is suitable for real-time data transmission. Here are a few recommended chips:

Realtek RTL8822CU

Features: Supports dual-band Wi-Fi, including 5GHz.

Advantages: Cost-effective, easy to integrate, suitable for developing temperature monitoring systems.


3. System Design and Implementation


Hardware Design

Sensor Interface: According to the selected temperature sensor (such as DS18B20 or LM35), design the corresponding interface circuit to ensure compatibility with the microcontroller.

Power Management: Considering the particularity of the swimming pool environment, design a waterproof shell protection circuit to ensure the durability of the equipment.


Software Development

Data Acquisition: Use the selected microcontroller to write a program to read the data of the temperature sensor regularly.

Data Processing: Filter and average the collected data to improve the measurement accuracy.

Display and Output: Display the current water temperature through LCD, and upload the data to the cloud via Wi-Fi for remote monitoring.


System Testing and Optimization

Test in the actual swimming pool environment, evaluate the measurement accuracy and response speed, and make necessary adjustments based on the results.


5. Future Development and Application

With the development of Internet of Things technology, future swimming pool temperature meters will achieve smarter monitoring and management. By integrating with the smart home system, users can check the water temperature in real time through their mobile phones and perform remote control. In addition, combined with AI technology, the system can analyze historical data, automatically optimize the water temperature setting, and improve the user experience.



So,Choosing the right Wi-Fi 5GHz chip is crucial to the development of a swimming pool thermometer. Through a reasonable combination of hardware and software, efficient and accurate temperature monitoring can be achieved, providing users with a better swimming pool experience. In the future, with the advancement of technology, such devices will continue to develop and provide more intelligent solutions for swimming pool management. Whether it is a home swimming pool or a commercial swimming pool, the application of a thermometer will significantly improve the safety and comfort of the swimming pool.
