ماژول تشخیص مانع حسگر مجاورتی مادون قرمز E18-D80NK

سنسور مادون‌قرمز D18 یک ماژول صنعتی برای تشخیص فاصله و مانع است که با ولتاژ تغذیه 5V DC و جریان حدود 100mA کار می‌کند. خروجی این سنسور از نوع Open Collector بوده و برای عملکرد صحیح باید با یک مقاومت 10KΩ به تغذیه متصل شود. فاصله تشخیص بسته به رنگ و جنس سطح مانع و همچنین حساسیت تنظیم‌شده توسط مولتی‌ترن پشت ماژول، در محدوده‌ای بین 6cm تا 80cm متغیر است؛ به‌طور معمول برای سطوح مشکی حدود 6cm و برای سطوح سفید تا 80cm فاصله را شناسایی می‌کند. این سنسور از بازتاب نور مادون‌قرمز برای شناسایی اجسام استفاده می‌کند و وضعیت تشخیص از طریق LED روی ماژول نمایش داده می‌شود. این محصول برای استفاده در رباتیک، سیستم‌های اتوماسیون صنعتی، اندازه‌گیری فاصله ، سیستم های شمارش کالا در خط تولید ، سیستم‌های امنیتی و پروژه‌های الکترونیکی بسیار مناسب است.

در راه اندازی این ماژول حتما پین خروجی را Pull up کنید .

نکته : ماژول E18-D80NK در دو مدل با کیفیت و معمولی تولید می‌شود که نوع معمولی خروجی غیر پایدار و نویز پذیر دارد ، نمونه فوق از نوع مرغوب است .

Description

The E18-D80NK Adjustable Infrared Proximity Sensor Module can be adjusted to sense objects over a range of 3-80cm.

PACKAGE INCLUDES:

• E18-D80NK Adjustable Infrared Proximity Sensor Module w/ attached 45″ cable

KEY FEATURES OF E18-D80NK ADJUSTABLE INFRARED PROXIMITY SENSOR MODULE:

• Extremely easy to setup and use
• Fully adjustable detection range from 3 to 80cm
• Simple logic and LED output indicates when object is detected
• Built-in 45″ cable
• 5V Operation
• Optional mounting bracket available

This is an extremely easy to use sensor that consists of an IR transmitter and receiver pair in one module.  The IR transmitter emits IR light and the IR receiver detects the IR light that is reflected off objects.

This is the larger version of the E18-D80NK.  The main difference is that the body is longer at 65mm vs 49mm and the cable is 45″ vs 17.5″.  Functionality is the same between both models.

The sensor was originally designed to automate the counting of objects moving along a production line, but it works equally well as an obstacle avoidance sensor on a robotic vehicle or any other applications where detection of objects or obstacles within its range is desired such as for a security system or monitoring a pet door.

Detection range is approximately 3-80cm.  The range is adjustable using a multi-turn screw on the back of the unit.  Turning the screw CW increases the range at which objects are detected.  Turning the screw CCW decreases the range.  If the adjustment is turned CCW too far, the module will no longer detect an object until it is turned CW again.  Similarly if it is turned CW all the way, it will always show a detection until it is turned CCW again.

The module can detect that presence of the object within the range it has been set for, but it cannot determine the distance to the object.

The signal output is normally held HIGH due to a built-in 10K pull-up resistor.  When an object is detected, the output drops to LOW as long as it is detected.  A red LED on the back of the module is lit when an object is detected.  The output is an open collector that can sink a max of 100mA.

The module operates at 5V.  Current draw is typically only 5mA though max current draw is rated as 25mA.

The body of the module is threaded and 2 knurled nuts are included which allow the sensor to be mounted in an 19mm hole that can be drilled through sheet metal or wood.  The amount of protrusion through the hole is adjustable using the nuts.

We also have an acrylic bracket available that can be used to mount the sensor which is handy for some applications such as robotic vehicles.
