Water Flow Sensor KZ-S5 with Temperature

The KZ-S5 Water Flow Sensor is a precision fluid flow measurement device with integrated NTC temperature sensing, designed for accurate monitoring of both water flow and temperature in various applications. This advanced dual-function sensor features a durable plastic body with a Hall-effect sensor that generates digital pulses proportional to the flow rate, while simultaneously measuring water temperature, making it perfect for smart irrigation systems, water heaters, coffee machines, beverage dispensers, and home automation projects.

Utilizing a magnetic rotor mechanism and built-in NTC thermistor, the sensor provides reliable pulse signals and real-time temperature data through its 4-wire output interface. This allows seamless integration with Arduino, Raspberry Pi, ESP8266, and other microcontrollers for comprehensive flow rate calculation, volume measurement, and temperature monitoring in a single compact module.

The 4-wire configuration provides dedicated connections for power supply, ground, flow pulse output, and temperature sensing, ensuring clean signal transmission and accurate readings. Constructed with food-grade materials suitable for potable water applications, the KZ-S5 offers excellent repeatability and accuracy across its operating range. Its robust construction and standard threaded connections make installation straightforward while ensuring long-term reliability in continuous operation environments including water heaters, tankless systems, and industrial fluid monitoring.
