Understanding the Electromagnetic Spectrum and Data Communication Frequency Bands In today’s connected world, data communication technologies rely on different frequency bands within the electromagnetic spectrum to transmit signals efficiently. Whether it’s Wi-Fi, mobile networks, satellite communications, or radio broadcasting, each technology operates within a specific frequency range to optimize performance and avoid interference. What is the Electromagnetic Spectrum? The electromagnetic spectrum refers to the range of all possible electromagnetic waves, from low-frequency radio waves to high-frequency gamma rays. The spectrum is divided into different regions based on frequency (measured in Hertz, Hz) and wavelength (measured in meters). Main Regions of the Electromagnetic Spectrum Radio Waves (3 Hz – 300 GHz) Used for communication technologies like AM/FM radio, television, and wireless networks. Microwaves (300 MHz – 300 GHz) Used in radar, satellite communications, GPS, and Wi-F...

Understanding MQ Gas Sensors and Interfacing with Arduino Uno Gas sensors play a vital role in monitoring air quality and detecting hazardous gases in the environment. The MQ series of gas sensors are widely used for their reliability, affordability, and ease of use. Each MQ sensor is designed to detect specific gases, making them versatile for various applications. In this blog, we’ll explore the features and applications of popular MQ sensors and learn how to interface them with an Arduino Uno . Overview of MQ Gas Sensors 1. MQ-135 (Air Quality & Hazardous Gas Sensor) Detectable Gases : Ammonia (NH3), Sulfide, Benzene, and Smoke. Applications : Air quality monitoring, pollution detection, and industrial safety. Output : Analog and digital. 2. MQ-2 (Smoke and Flammable Gas Sensor) Detectable Gases : Methane (CH4), Propane, Butane, Smoke, and LPG. Applications : Smoke detectors and gas leakage systems. Output : Analog and digital. 3. MQ-3 (Alcohol Sensor) Detecta...
