Water Level Sensor Pinout The working principle of the water level sensor module is very similar to that of a Rain Sensor. The water level sensor has three pins, runs on 5V power, and gives out the ...

Circuit Fig. 3 shows the circuit diagram of the automatic water level indicator cum controller. It is built around an Arduino Uno board (MOD1), three LEDs, a 5V SPDT relay, and other components. First ...

The basic design idea is to set two ports of the MCU for water level detection, one port for automatic/manual mode switch selection, and two ports for visual status indication. From the reading of the ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

When the sensor detects that the moisture content is already below 30%, it sends a signal to the Arduino, which, in turn, activates a water pump to provide hydration to the plant.
