Overview

Industrial-grade Hall-effect turbine flow sensors (DN40 / DN50) designed for high-flow water measurement. The sensor outputs a digital pulse signal proportional to flow rate, providing stable, high-precision measurement with fast response and excellent sealing. Suitable for IoT, industrial equipment, agricultural irrigation, and automatic water control systems.

Introduction

เซนเซอร์วัดอัตราการไหลของน้ำแบบ Turbine Hall Sensor รองรับท่อน้ำ 1.5 นิ้ว (DN40) และ 2 นิ้ว (DN50) ให้สัญญาณออกเป็น Digital Pulse ง่ายต่อการอ่านผ่าน Arduino, ESP32, STM32, PLC หรือระบบ IoT ต่าง ๆ มีคุณสมบัติทนแรงดันน้ำสูง ไม่รั่วซึม วัสดุไนลอนแข็งแรง ได้มาตรฐาน ROHS พร้อมความไวสูง

Features

  • Digital Hall-effect Pulse Output — ต่อเข้ากับ Arduino/ESP32 ได้โดยตรง
  • รองรับแรงดันไฟกว้าง DC 3.5–24V
  • วัสดุ Nylon ทนกัดกร่อนและแรงดันน้ำสูง ≤1.75MPa
  • ค่าความไวสูง ให้สัญญาณ Pulse คงที่แม้ที่อัตราการไหลสูง
  • ได้มาตรฐาน ROHS, ความแม่นยำ ±3%–±5%
  • ใช้งานได้ช่วงอุณหภูมิกว้าง และผ่านการทดสอบความเย็น -20°C และความร้อน 85°C

Exchange or return policy



Every item comes with a 30-day warranty. However, there are certain conditions that apply:

  1. The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).

  2. The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).

  3. The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.

Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:

  1. Provide a detailed description of the damaged item(s).
  2. Mention any tests or experiments conducted by the customer.

Please note that the store reserves the right to make the final decision regarding product replacement or refund.
