In this IoT internet of things project, I have explained how to make an IoT based water level indicator project using NodeMCU ESP8266 Blynk and ultrasonic sensor. For the LOW water level, the pump will start automatically and you will get a Blynk notification on the smartphone through the internet. Also, you can monitor the water tank level on OLED.
For this NodeMCU ESP8266 water level indicator project, you can use any ultrasonic sensor as the water level sensor in the tank. You can always monitor the tank water level on OLED and if the NodeMCU is connected to WiFi, you can monitor the water level from anywhere in the world on Blynk IoT App.
In Manual mode, you can control the water pump manually from the switch and Blynk app.
The alarm will ring when the tank is full and when the water level drop below the threshold limit.
During this video, I made the circuit on zero PCB using the PCB layout, and also shared the wireless automatic water level controller circuit and source code.
If you want you can connect a relay to the control pump, otherwise you can use this IoT Project as the water level indicator.
