Thermostat with Color Touchscreen and Cloud Connection

In home appliances, the thermostat is used for central control. Traditional mechanical thermostats are being replaced by the segment-LCD screen-controlled versions and Renesas’ Synergy S5D9 MCU supports cloud connectivity as well as LCD control. 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). The RX231 MCU voice recognition reference design enables customers to quickly evaluate and implement voice control. The ISL32704E supports a fully isolated ESD RS-485 interface which adds robustness in the electronically noisy environment that exists in modern homes. The HS300x provides high accuracy and excellent stability for measuring humidity and temperature.
