Infrared thermometers measure temperature from a distance by detecting infrared radiation. They offer non-contact, fast, and accurate readings, making them ideal for applications in healthcare, industry, and everyday use. Learn more about their types and uses.

An accelerometer is a motion-sensing device that measures acceleration and vibration. Learn how accelerometers work, their types (MEMS, piezoelectric, etc.), key uses in electronics and industry, and how to choose and interface them in your projects.

A thermistor is a temperature-sensitive resistor used in sensing, control, and protection. Learn how thermistors work, their types (NTC/PTC), materials, circuits, applications, pros/cons, how to test them, and tips for choosing the right one.

A PID controller regulates systems by adjusting output based on proportional, integral, and derivative terms. Learn how PID works, its types (P, PI, PD, PID), tuning methods, and real-world uses in temperature, speed, and industrial control.

A thermocouple measures temperature using two dissimilar metals and the Seebeck effect. Learn how it works, types (K, J, T, etc.), insulation, applications in industry and appliances, how to choose the right one, troubleshoot issues, and explore alternatives.

Control systems regulate machines and processes using sensors, controllers, and actuators. Learn how they work, key types (open/closed-loop), real-world applications, design challenges, and trends like AI, IoT, and cloud-based automation.

A 7-segment display uses seven LEDs to show numbers and some letters. Learn its structure, types (common anode/cathode), pinout, how it works, interfacing with microcontrollers, key differences vs. 14/16-segment displays, and common troubleshooting tips.

IR sensors detect infrared radiation, while IR LEDs emit it. Together, they enable motion detection, proximity sensing, and remote control. Learn how they work, key specs, types, differences, benefits, and real-world uses in electronics and automation.
