Renesas ISL9111A | Demoboard EU154 Smart Water Shutdown Valve

ISL9111A

Overview

TopologySensors
Input voltage0.5-5 V
IC revision1

Description

Sometimes flooding occurs due to broken water pipes, but often we don't realize it until it is too late. Together with Renesas' Smart Water Leakage Sensor, this shutdown valve solution can automatically take countermeasures without human interaction in such cases. Then, this solution can reduce or completely avoid damage caused by water spilling due to broken pipes via shutdown of the water supply.

Features

Shut off spilling water using Wi-FiIndication of inappropriately high moisture level/water spilling comes from our Smart Water Leakage Sensor or by manual command, e.g., via MQTTBattery backup keeps the system alive when mains power failsSolar energy harvesting allows for sensor use without mains powerUltra-low power DC/DC + Wi-Fi allows for long operation/standby timeBT5 to ease commissioning via smartphone

Typical applications

  • Smart Water Valve, Sensors, Automation
