Sensor Modules
Sensor modules are hardware components that detect and measure physical properties such as temperature, motion, light, or pressure, converting them into electrical signals for processing by microcontrollers or computers. They are essential in embedded systems, IoT devices, and robotics for gathering real-world data. Common types include environmental sensors (e.g., DHT11 for humidity), motion sensors (e.g., PIR), and proximity sensors (e.g., ultrasonic).
Developers should learn about sensor modules when building IoT applications, smart devices, or automation systems that require environmental monitoring or interaction with the physical world. They are crucial for projects involving data collection, home automation, industrial control, or robotics, enabling real-time feedback and decision-making based on sensor inputs.
