Overview

Description

This design demonstrates an air duct system that purifies the air inside homes by sensing the temperature, humidity and air quality. The RL78 microcontroller (MCU) series has a variety of functions and a wide lineup, as well as a standby function to reduce current consumption to minimize standby power. The RX23T MCU also enables efficient motor control.

System Benefits:

  • Minimize standby power with the RL78 MCU series
  • Efficient motor control with the RX23T MCU
  • Temperature/Humidity and gas sensors protect air quality and support filter exchange detection
