Application of Bluetooth Modules in Smart Toilets

Background

With continuous technological advancements and improving living standards, smart home devices are becoming increasingly popular. Smart toilets have become an essential part of enhancing home life quality.

To further improve user experience, the adoption of Bluetooth-enabled smart toilets and Bluetooth remote controllers has become a trend.

Solution Design

System Architecture

The Bluetooth smart toilet system consists of the following components:

• Smart Toilet Unit: Includes sensors, heating system, washing system, drying system, and more.
• Bluetooth Module: Built into the toilet to enable wireless communication with the remote controller.
• Bluetooth Remote Controller: A handheld device for controlling the toilet’s functions.
• Mobile Application (Optional): Connects to the smart toilet via Bluetooth, allowing remote control and personalized settings.

Function Design

Bluetooth smart toilets and controllers should include the following features:

• Automatic Flushing: Uses sensors to detect user departure and trigger flushing.
• Seat Heating: Adjusts seat temperature based on user preferences for comfort.
• Water Temperature Adjustment: Enables users to control water temperature via the remote or mobile app.
• Drying Function: Provides warm air drying to reduce paper towel usage.
• Energy-Saving Mode: Supports scheduled shutdown and low-power standby.
• Personalized Settings: Saves multiple user profiles for customized use.

Implementation Plan

1. The smart toilet uses the RHA-BT102M low-power Bluetooth module, which supports one-master-two-slave functionality and communicates with the toilet's main control system via UART.
2. The smartphone serves as the master device, connecting to the RHA-BT102M, allowing control through a mobile app or mini program.
3. The remote controller uses the RHA-MY3003 chip, supporting Bluetooth 5.2 to enable communication and control functions.
4. The RHA-BT102M acts as the master device, connecting to two remote controllers.
5. The RHA-BT102M synchronizes received data with the phone and controllers, ensuring data consistency.
6. By default, the remote controller enters sleep mode after 10 seconds of inactivity.

Future Outlook

The design of Bluetooth smart toilets and controllers leverages modern Bluetooth technology to deliver intelligent, convenient, and personalized user experiences. Through optimized hardware and software development, this solution significantly enhances the usability of smart toilets, offering users a higher-quality lifestyle.

In the future, as IoT technology continues to evolve, smart toilets could integrate with other home devices, creating smarter, more personalized living environments. For instance, voice assistants could control toilets, or big data analysis might provide precise health management advice.

Bluetooth smart toilets will transcend their role as simple household devices, becoming a key component of the smart home ecosystem.
