🔬 What is a Sensor?
Sensor" is an enormous and crucial topic, as these devices are the "eyes, ears, and skin" of the digital world, bridging the gap between the physical environment and electronic systems.
Here is a comprehensive overview of what a sensor is, how it works, the different types, and where innovation is headed in 2025.
A sensor is a device that detects, measures, and responds to some kind of input from the physical environment. The input can be a physical phenomenon like light, heat, motion, pressure, moisture, or a chemical change.
Sensing (Reception): The sensor's receptor element physically interacts with the environmental stimulus (e.g., pressure on a diaphragm, light hitting a photodiode).
