M18 E3F-DS30C4 NPN Photoelectric Cylindrical Sensor

Description

What is the M18 E3F-DS30C4? The M18 E3F-DS30C4 is an 18 mm diameter threaded cylindrical photoelectric proximity sensor. It uses a light beam to detect objects. Features Dimensions: 18 mm diameter Type: Optical proximity sensor Output type: NPN Shape: Cylindrical Threaded connection: Check the datasheet Applications This sensor is ideal for home automation, security, and robotics projects. It can be used to create domestic alarm systems that trigger an alert light when an object interrupts the sensor’s light beam or to monitor object movement in automated environments. Compatibility with Arduino and ESP needs verification from the datasheet. Tutorial: How to use E3F-DS30C4 Photoelectric Sensor The E3F-DS30C4 photoelectric sensor is used for detecting objects through emitted light beams. This component is suitable for home automation, security, and robotics projects. What you need Arduino Uno USB cable Breadboard Jumper wires Indicator light Steps Connect the sensor to the breadboard Supply power to the sensor (check datasheet) Connect the sensor output to an Arduino digital pin Upload the example sketch to the Arduino Check that the indicator light changes when an object interrupts the light beam Example code const int ledPin = 13; // define output pin const int photoPin = 2; // define input pin void setup() { pinMode(ledPin, OUTPUT); pinMode(photoPin, INPUT); } void loop() { int sensorValue = digitalRead(photoPin); if (sensorValue == HIGH) { digitalWrite(ledPin, HIGH); } else { digitalWrite(ledPin, LOW); } } Mini-project Create a domestic alarm system that triggers an alert light when an object interrupts the sensor’s light beam. Common mistakes Not checking power supply voltage on datasheet Incorrectly connecting the sensor output to an Arduino digital pin Failing to test the sensor before integrating it into a project Not adding a capacitor to filter electrical interference Recommended accessories Arduino Uno Breadboard Jumper wires Indicator light Frequently Asked Questions Does the sensor work in bright conditions?
