Description

The water level sensor is a simple 3-pin module that provides an analog signal typically ranging from 0 to 500, which gives an approximate measure of the water’s depth or submersion level. When this sensor is paired with a pull-up resistor, it can also function as a digital device to indicate the presence or absence of water.

In its analog mode, the sensor’s output signal varies in proportion to the water level. The value typically starts at 0 when there is no water and increases as the water level rises. This analog output can be connected to an analog-to-digital converter (ADC) or microcontroller to obtain precise water level measurements.

When configured as a digital device with the help of a pull-up resistor, the sensor essentially acts as a binary switch. In this mode, it provides a high or low signal, indicating whether water is present or not. The pull-up resistor ensures that the signal remains high when there is no water, and it goes low when water touches the sensor, completing the circuit and changing the signal state.

This dual functionality makes the water level sensor a versatile tool for applications where you need to monitor water levels or simply detect the presence of water. Depending on your project’s requirements, you can choose between the analog mode for more precise measurements or the digital mode for basic water presence detection.
