Thermostat with Color Touchscreen and Cloud Connection

In home appliances, the thermostat is used for central control. In traditional thermostats, the mechanical thermostat is being replaced by the segment-LCD screen, but the control keys are still essentially mechanical.

This thermostat design enables users to connect to the cloud and increase to a larger size color screen for ease of use and a better Human Machine Interface (HMI). In this solution, the Synergy S5D9 MCU supports cloud connectivity as well as LCD control. The RX231 MCU voice recognition reference design enables customers to quickly evaluate and implement voice control. The ISL32704E transceiver supports a fully isolated ESD RS-485 interface which adds robustness in the electronically noisy environment that exists in modern homes. And, the HS300x sensor provides high accuracy and excellent stability for measuring humidity and temperature.
