Smart Water Leakage Sensor

In recent times, flooding occurs more frequently due to climate change, but often we recognize it too late. Sometimes this is also caused by broken water pipes. This sensor solution informs the residents/building operator early or automatically triggers shut-off valves. Hence, countermeasures are/can be taken before it is too late to reduce or avoid damage.

System Benefits​:

• Detection of inappropriately high moisture level/water spilling
• Wi-Fi indication to user or to shut-off valve, e.g., by MQTT
• Battery backup keeps the sensor 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 (LE) 5 to ease commissioning via smartphone
