About Sensors and Modules
Sensors and modules are the foundation of electronics projects, robotics, and automation systems. Ultrasonic distance sensors like the HC-SR04 provide accurate range measurement, while infrared modules are commonly used for obstacle avoidance and line-following robots. Relay modules enable safe switching of high-power devices, and voltage sensors monitor electrical levels in real time. Specialized tools such as thermocouples measure temperature, flame sensors detect fire hazards, and joystick modules bring interactive control to robotic systems. With additional components like I2C adapters for LCDs and LED traffic light modules for learning circuits, these modules offer versatility, reliability, and ease of integration into both beginner and advanced projects.
FAQs
Q1. How does the HC-SR04 ultrasonic sensor measure distance?
It sends out ultrasonic waves and calculates distance by measuring the time it takes for the waves to bounce back after hitting an object.
Q2. What is the purpose of the I2C module for LCD displays?
The I2C adapter reduces the number of pins required to connect an LCD to a microcontroller, simplifying wiring and freeing up resources for other components.
Q3. Where is a flame sensor module commonly used?
It is often used in fire-detection systems, safety alarms, and robotics projects where flame detection is required for safety or automation.
Q4. Can the TCRT5000 IR sensor module track multiple lines?
Yes, the 5-channel version can track multiple lines simultaneously, making it suitable for line-following robots with complex navigation paths.
Q5. What is the function of a relay module in electronics projects?
A relay module acts as a switch controlled by a low-power signal from a microcontroller, allowing safe control of higher voltage devices like fans, lights, or pumps.
