IoT Water Control and Monitor Using NodeMCU & Cayenne

About This Project

I'll try to create an IoT water control and monitoring system using Cayenne. The valve will close when water reaches the top level of the sensor.

This project is to ensure that the water reservoir is always full, because in my area the water supply may only flow at midnight, but at midnight we are not in need of water.

What's Connected

• NodeMCU ESP-12E

• Liquid Level Sensor (calibrate first to get top level value and bottom level). If you need a deeper sensor, you can cut the top strip of the sensor and take some wire to the two sides of the sensor

• 1 CH Relay Module

• 12V Solenoid Valve

• 12V 2A Power Supply

Triggers & Alerts

Add triggers and set: if water level rises above 100%, then the valve switch turns off. Add triggers and set: if water level falls below 100%, then the valve switch turns on.

Scheduling

No scheduling was added.
