Most reliableWater Level IndicatorIOTESP8266innovationWater tank overflow is a common problem which leads tothewastageofwater.Thoughtherearemanysolutions to it like ball valves which automatically stop the water flow once the tank gets full and transistor based which sends low electricity into water. ...
In this IoT project, we will create a water level monitoring web server using an HC-SR04 Ultrasonic sensor and ESP32. It will be a contactless water level measurement system. First, we will learn to interface HC-SR04 with ESP32. After that, we will see program our ESP32 board with the...
If you want to compile this image yourself be sure to use the mentioned libraries and support for a filesystem on the esp8266 so select the correct flash option in arduino ide for that. When starting, without a configured wifi, an open-wifi-hotspot will be visible allowing you to configure...

Development of the smart sluice gate used the NodeMCU ESP 8266 microcontroller and soil moisture sensor and ultrasonic sensor HC/SR 04 with other supporting components. The water discharge generated at smart sluice gates is more varied with the average efficiency of smart sluice gates is 64%, ...
you can also considerinterfacing a pH meter with Arduinoand also read the pH value of water to better assess the quality of water. Previously we have also built anIoT based Water quality monitoringdevice using ESP8266, you can also check that out if interested. That ...
5V for the sensor is taken from the "USB out" pin on the ESP8266 board. The signal of the sensor is connected to the Arduino via a Level Shifter board.HERE Step 2: Wiring It Together on the Bench for Initial Testing 3 More Images ...
You will need the following items to build a DIY water level sensor cum alarm. ESP8266 microcontroller, such as NodeMCU or D1 Mini 433MHz wireless transmitter and receiver module—buy one or build your own using HT12E/HT12D encoder decoder ICs and 433MHz transmitter and receiver circuit modul...
