Definition and types of sensors
An IoT sensor is a physical device that monitors and collects data from the environment around it. It then sends that data to an IoT platform for further analysis. There are many types of IoT sensor, each designed to measure a specific type of data. Some common types of IoT sensors include temperature, humidity, motion, light, and pressure sensors.
These sensors can be found in all sorts of locations, from warehouses, manufacturing equipment, outside in the arctic circle and even within smart devices.
