Frequently Asked Questions

What is the operating voltage range for this liquid level sensor?

The sensor operates from 2.0V to 5.0V DC, making it compatible with both 3.3V and 5V microcontroller systems such as Arduino, Raspberry Pi, and ESP32 without requiring a level shifter.

How do I interface this sensor with an Arduino?

Connect the sensor's power pins to your board's 5V (or 3.3V) and GND. Connect the analog output pin to one of the Arduino's analog input pins (e.g., A0). The output voltage will increase with immersion depth, which you can read using the analogRead() function.

What liquids is this sensor suitable for?

This sensor is designed for use with non-corrosive, non-toxic liquids such as water. It is not intended for use with conductive, corrosive, or food-grade liquids, as these may damage the exposed PCB traces.

How do I mount the sensor securely?

The PCB includes 2.0mm diameter mounting holes. Use M2 screws or standoffs to secure the sensor vertically in your application, ensuring the sensing traces are fully immersed for accurate level detection.
