Description
Product Description
The liquid level sensor module measures liquid height in real time and converts water level status into electrical signals readable by a controller. It is suitable for water tanks, aquariums, water purifiers, drinking machines, automatic refill equipment, and industrial liquid-level monitoring systems.
Sensor Types
Electrode water-level sensors use conductive probes touching the water surface to form a circuit and are suitable for single-point alarms. Non-contact capacitive sensors can be attached to the outside wall of non-metal containers without drilling holes. Photoelectric level sensors use optical refraction to detect liquid level and are compact and accurate. Float sensors output on/off signals through a reed switch. Pressure sensors are suitable for deep-water or continuous level measurement.
Electrical Parameters
Common operating voltages include DC 3.3V, 5V, and 12V. Output signals can be high/low level, analog voltage, 4-20mA current, or digital protocols such as I2C and UART. Detection range can vary from small containers of a few centimeters to pools several meters deep, with a regular operating temperature around -10°C to 60°C.
Wiring and Use
When connected to microcontrollers such as Arduino, ESP32, or STM32, VCC connects to positive power, GND to ground, and OUT or the signal pin to the controller input. The controller can control pumps, valves, or buzzers based on water level status. For food, medical, or corrosive liquid applications, choose probes with matching materials and certification levels.
