This topic introduces the solutions for the humidifier and provides developers with the solutions for the integration of Tuya humidifier products.

Solution overview

With the improvement of people’s living standards, the widespread use of air conditioners in summer and the warm air in winter have increased human skin tightness, dry mouth, cough, and cold. The humidifier can effectively increase the indoor humidity, moisturize the dry air, and combine with the floating smoke and dust in the air to make it precipitate. It can effectively remove the smell of paint, musty, smoke and odor, and make the air fresher. With the rise of smart products, in order to meet the needs for smart home appliances, app remote smart control, and third voice assistants have gradually become indispensable. People can realize the timing setting or remote function control of humidifier products through the app or voice control, so as to realize a convenient and high-quality life.

Tuya provides the leading global Developer Platform that enables consumers, manufacturers, brands, OEMs, and retail chains to develop one-stop AIoT solutions. For humidifier products, three solutions including hardware access, cloud services, and App software development are currently available to meet the higher demands of consumers for humidifying aromatherapy products.

As one of the most frequently-used solutions to connect to the Tuya Developer Platform, the MCU connection solution is mainly used to enable products with MCU to be smart. It is mainly used to IoT-enable the humidifier products with MCU master control. It can be connected to the serial port protocol of the Tuya module directly to realize networking. Customers only need to pay attention to the function research and development of the product itself, and the smart part of the network uses the public version of the solution. The specific communication schematic diagram of the MCU solution is as follows:
