The DFRobot Gravity Liquid Flow Sensor (G1/2) is designed to measure the flow rate of liquids in pipes or systems with a G1/2 thread. Featuring a durable construction, it provides accurate and real-time flow data for water, oils, and other compatible liquids. The sensor operates based on a magnetic induction system, offering high sensitivity and reliability. It is equipped with a Hall effect sensor, which generates electrical pulses corresponding to the liquid flow, making it easy to integrate with microcontrollers like Arduino. Ideal for applications such as water flow monitoring, irrigation systems, and fluid dispensing, it offers precise, low-maintenance performance.
