There are various types of sensors available that are used for various applications such as data collection from the environment. The primary role of these sensors is to collect data from their surroundings. Once the signal conversion and processing are completed, these can be connected to IoT devices directly or indirectly. Because different IoT applications require different types of sensors like Wireless Vibration Sensor, Remote Thermometer sensors, IoT Environmental Sensors, and so on, no two sensors are the same.
