Water Flow Sensor ZJ-S201C

🔹 Water Flow Sensor ZJ-S201C – Hall Effect Flow Meter (G1/2″ Thread)

The ZJ-S201C is a commonly used water flow sensor that uses a Hall effect to measure the flow rate of water passing through it. It outputs pulses corresponding to a certain volume of water, which microcontrollers (Arduino, ESP32, Raspberry Pi, etc.) can interpret to calculate flow rate and volume.

✅ Specifications:

• Model: ZJ-S201C

• Thread Size: G1/2″ (common plumbing thread)

• Output: Pulse signal (Hall effect)

• Flow Range: ~ 1 – 30 L/min (depends on sensor & conditions)

• Operating Voltage: 5V DC

• Water Temperature Range: ~ 0 – 100 °C

• Connector: 3 wires (VCC, GND, Signal)

• Material: Plastic body, rotor inside

📦 Applications:
✔️ Water flow measurement systems
✔️ Smart irrigation / garden automation
✔️ Water dispenser meters
✔️ Liquid volume counters
✔️ Monitoring pumps, tanks, or plumbing systems
✔️ DIY projects & environmental sensors
