Product description What this sensor does Accurate water flow measurement in the range of 1–30 L/min. Acts as a flowmeter and counter sensor to provide consistent flow data for monitoring and control. Built as a 1/2" water flow sensor switch for straightforward plumbing installation. Why you need it Detect and quantify water usage precisely to prevent waste, verify system performance, or log consumption. Provides the control signal needed for automatic systems and DIY controllers—compatible with Arduino projects for real-time monitoring and automated responses. Reliable, repeatable readings reduce guesswork and downtime in applications that depend on steady flow rates. Key benefits and features Measurement range: 1–30 L/min — suitable for low- to medium-flow water applications. 1/2" form factor: standard threaded size for easy fitting into many water lines and plumbing setups. Control-ready output: provides a usable signal for Arduino and similar microcontroller platforms to enable automated control, counting, or data logging. High precision and reliability: delivers stable flow data to support consistent system operation and accurate reporting. Simple installation: compact design and common thread make it convenient to mount and integrate. Typical applications Irrigation and garden systems: monitor and control water delivery to zones, detect blockages or leaks, and log consumption. Water dispensers and pumps: ensure correct flow rates, enable automated shutoff or dosing, and support maintenance diagnostics. Arduino projects and prototypes: integrate into hobbyist or professional projects for flow measurement, control loops, and data collection. What to expect A compact 1/2" flow sensor that measures water flow between 1 and 30 L/min and provides a stable output suitable for monitoring and control with Arduino-based systems and similar controllers.
