IoT Sensors
IoT sensors are physical devices that detect and measure environmental conditions or physical phenomena, converting them into digital data for transmission over networks. They are fundamental components of the Internet of Things (IoT), enabling real-time monitoring and automation in various applications. Common types include temperature, humidity, motion, pressure, and light sensors, often integrated with microcontrollers and wireless communication modules.
Developers should learn about IoT sensors when building IoT systems for smart homes, industrial automation, healthcare monitoring, or environmental tracking, as they provide the raw data needed for decision-making and control. Understanding sensor selection, calibration, and integration is crucial for ensuring data accuracy, system reliability, and efficient resource usage in embedded and edge computing projects.
