Overview

Description

In this reference design, Renesas' Smart Water Shutdown Valve together with our Smart Water Leakage Sensor can automatically control a valve to start/stop water flow. Therefore, automatically taking countermeasures without human interaction. This solution can reduce or completely avoid damage caused by water spilling due to broken pipes via shutdown of the water supply. In another use case, it can intentionally start water flow to water plants and stop the water when they have sufficient water level. This design utilizes the standard MQTT visualization tools to detect high moisture levels or water spills and shut down the valve using the DA16600MOD ultra-low power Wi-Fi + Bluetooth® Low Energy (LE) combo module.

Features

  • Shut off spilling water using Wi-Fi
  • Indication of inappropriately high moisture level/water spilling comes from our Smart Water Leakage Sensor or by manual command, e.g., via MQTT
  • Battery backup keeps the system alive when mains power fails
  • Solar energy harvesting allows for sensor use without mains power
  • Ultra-low power DC/DC + Wi-Fi allows for long operation/standby time
  • Bluetooth Low Energy 5.0 to ease commissioning via smartphone
