Overview

Product Overview

ZJ-S201 water flow sensor is a G1/2" inline flow meter for measuring and monitoring liquid movement from 1–30L/min in water dispensing, irrigation, cooling, filtration, and appliance projects. Built for Arduino, Raspberry Pi, and ESP32 systems, this water flow sensor helps you track consumption, confirm that water is flowing, and trigger smart responses such as pump control, shutoff logic, or usage logging in home automation and prototyping setups. The ZJ-S201 is well suited to embedded monitoring, DIY plumbing experiments, and compact maker builds that need dependable real-time flow sensing across microcontroller and SBC projects.

Questions & answers

Frequently asked questions

Yes, the ZJ-S201 water flow sensor is compatible with Arduino. It can be easily interfaced using available digital pins to track water flow rates and integrate with Arduino-based home automation or prototyping projects.
The ZJ-S201 sensor comes pre-soldered and ready for use. Connect it inline with your water system and attach the output wires to your microcontroller to start measuring flow rates. Calibration may be required for precise applications.
The ZJ-S201 water flow sensor typically uses a Hall effect sensor with a digital output. You connect it to digital I/O pins on a microcontroller, where it inputs pulse signals proportional to the flow rate.
Yes, the ZJ-S201 is suitable for home irrigation projects. Its ability to measure flow rates from 1–30L/min allows it to monitor water distribution effectively and trigger responses such as valve operation or alerts in intelligent irrigation setups.
If the ZJ-S201 sensor displays incorrect flow rates, ensure it is installed correctly and that there are no blockages. Verify all connections to your microcontroller and consider recalibrating the sensor to improve accuracy.
