4-CH IR Line Sensor Module

A 4-channel IR line sensor module is a type of sensor that uses infrared (IR) technology to detect the presence or absence of a line or object. It typically consists of four individual IR sensors, each with its own phototransistor, that are arranged in a row. The module can be used to detect the position of a line, the edge of an object, or the presence of an obstacle in a robotic or automation application. It is often used in line-following robots, edge detection, and other similar applications.

      1. What is an IR Sensor and why is it not visible?

      • An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Infrared radiation was accidentally discovered by an astronomer named William Herchel in 1800. While measuring the temperature of each color of light (separated by a prism), he noticed that the temperature just beyond the red light was highest. IR is invisible to the human eye, as its wavelength is longer than that of visible light. Anything that emits heat gives off infrared radiation

      2. What are the types of IR sensor and their difference?

      • There are two types of infrared sensors: active and passive:
        • Active infrared sensors both emit and detect infrared radiation.
        • Passive infrared (PIR) sensors only detect infrared radiation and do not emit.
