Flow sensor for Halltype automatic water dispensers Flow range: 0.01–0.1 /h Operating voltage: 5–24 V Threewire connection: red for V, black for GND, yellow for output Compact, lightweight design for easy integration and portability Compatible with Halleffect based water dispensing systems Suitable for integration with microcontrollers or control boards via the output signal Applications and use scenarios Replacing or upgrading the flow sensing function in a Halltype automatic water dispenser to monitor water flow and enable control logic for dispensing. Use in DIY beverage machines (such as espresso or hot water dispensers) where accurate flow detection is required to manage dosing and ensure safe operation. Integration in small irrigation or hydroponic systems to monitor water flow and trigger pumps or alerts when flow is outside expected ranges. Key benefits Clear, threewire connection simplifies wiring: red V, black ground, yellow output Compact and lightweight foot print allows installation in tight spaces Wide operating voltage range supports flexible power supply options Designed specifically for Halleffect flow sensing applications in automatic water dispensing systems Notes Material and housing details are not provided; the description focuses on function, compatibility, size, and performance attributes as specified.
