Smart Room Controller with DAB Audio System

Smart rooms not only provide health benefits but also give people a luxurious lifestyle. This smart room controller design features sensors that monitor room temperature and humidity, while an indoor gas sensor detects total volatile organic compounds (TVOCs) and estimated carbon dioxide (eCO₂) levels. Intelligent control is facilitated through voice recognition and touch keys. A highly integrated device for Digital Terrestrial Multimedia Broadcast (DTMB) ensures superior quality and acoustic enjoyment.

System Benefits​:

• 200MHz Arm^® Cortex^®-M33 with capacitive touch sensing unit (CTSU) and voice recognition firmware.
• High-performance AC/DC and low dropout voltage regulator (LDO) devices provide efficient power.
• High-performance gas sensor and relative humidity and temperature sensor provide comfort and safety.
