This solution provides an improved user experience for a developing application - the tankless gas water heater. By utilizing two controllers - one in the kitchen and the other in the bathroom - the user can control the water temperature and amount of water remotely.

Renesas has developed this solution by utilizing a two-chip MCU solution that provides a compact design with minimal expense. The design includes an MCU, sensor and connection modules like Bluetooth® Low Energy (BLE) or Wi-Fi and a high-accuracy temperature/humidity sensor with up to ±1.5%RH

System Benefits:

  • A single power solution for the entire system, enabling continuous long distance control without interruption
  • Accurate temperature and humidity control
