User Guide / How to Use

Using the water level sensor is simple and beginner-friendly. Connect the sensor to your development board (Arduino, ESP32, ESP8266, or Raspberry Pi) by wiring the VCC pin to a 3V–5V power source, the GND pin to ground, and the signal pin to an analog input pin. Once connected, the board will read varying analog values depending on the water level detected. These values can then be programmed to trigger alerts, activate motors, or log data for monitoring purposes.

Frequently Asked Questions (FAQs)

• What voltage does this sensor operate on?
  It operates on DC 3V - 5V.
• Can this sensor work with Raspberry Pi?
  Yes, it can be used with Raspberry Pi through an ADC module since it provides analog output.
• Is it waterproof?
  The sensor is water-sensitive but not waterproof. It should not be submerged completely in water.
• How do I know if the sensor is detecting water?
  The analog output value will increase when water touches the sensor’s detection area.
• Can I use this for long-term outdoor projects?
  Yes, but it is recommended to protect the sensor with a waterproof casing for durability.
