DFRobot Gravity Photoelectric Liquid Level Sensor for Arduino
High-accuracy DFRobot Gravity liquid level sensor for Arduino, Raspberry Pi. ±0.5mm accuracy, corrosion-resistant, 5V DC.
The DFRobot Gravity Photoelectric Liquid Level Sensor is a high-accuracy liquid level sensor designed for Arduino, Raspberry Pi, Intel Edison, Joule and Curie boards. With a corrosion-resistant probe that withstands high temperature and high pressure environments, this sensor offers reliable liquid level detection in demanding applications. Its ±0.5mm detection accuracy and 50,000-hour working life ensure precise, long-term performance.
The sensor features a plug-and-play Gravity 3-pin interface, making it easy to connect to Arduino via an IO expansion shield. It operates at 5V DC with a 12mA output current and supports an operating temperature range from -25°C to 105°C. The low-level output is below 0.1V, while the high-level output exceeds 4.6V, ensuring clear signal detection.
