Overview  

IoT sensors are key components in the Internet of Things (IoT) ecosystem, enabling devices to collect and share data in real-time. These sensors gather information from the physical environment—such as temperature, humidity, pressure, light, motion, and more—and transmit it to a central system for analysis and decision-making.

The types of IoT sensors vary widely depending on the application. Common types include temperature sensors, proximity sensors, accelerometers, gyroscopes, humidity sensors, light sensors, and pressure sensors. They are used in industries like healthcare, manufacturing, agriculture, and smart homes, where they monitor conditions and help automate processes. 

IoT sensors are often connected through wireless networks such as Wi-Fi, Bluetooth, Zigbee, or cellular networks. These sensors play a crucial role in predictive maintenance, resource optimization, and improving efficiency. For instance, in agriculture, soil moisture sensors monitor irrigation needs, while in smart cities, air quality sensors help manage pollution levels.
