5V Optical Liquid Level Sensor Module

Bring liquid level detection into an Arduino, 51 or STM32 project with a 5V optical sensor module.

Turn a liquid level change into a usable signal

The module provides analog and digital outputs, giving you a choice of voltage sampling or threshold-based detection. A potentiometer adjusts the digital trigger point, while the 4-pin XH-2.54 interface connects the supported FS-IR02 sensor. It suits projects such as reservoir level reminders and overflow monitoring.

Product details: 5V DC supply; current below 12mA; analog output 0–5V; digital output; XH-2.54 sensor interface. A 3.3V supply is not supported. Keep the rear of the sensor dry and match the wiring before use.

Add a practical level-sensing input to your next project.
