The Mini Liquid Level Sensor Module is a compact and efficient analog sensor designed to detect and measure liquid levels in small containers and tight spaces. This sensor is ideal for monitoring water levels, creating liquid alarms, and integrating into automation systems where precise liquid detection is required.

Designed to be inserted vertically into liquids, this module can detect fluid levels from 0mm to 48mm with high sensitivity. It outputs an analog signal that can be easily read by microcontrollers such as Arduino, ESP32, Raspberry Pi (via ADC), STM32, and other embedded systems. Its fast response time ensures accurate and real-time liquid level monitoring.

This sensor is suitable for non-corrosive and non-toxic liquids and is widely used in DIY electronics, industrial automation, reservoir monitoring, and smart water systems in Bangladesh. The included extension cable and mounting holes make installation simple and convenient.
