Sensors are critical components of IoT devices that enable them to capture and transmit data to other devices or
        the cloud for analysis and processing. IoT sensors (also called IoT devices)  are used to detect changes in the physical
        environment and transmit them to other devices (possibly over the Internet) as electrical signals. These sensors can be
        used to monitor a wide range of environmental factors, such as temperature, humidity, pressure, light, sound, motion,
        and location.
        IoT sensors are often small and low-cost, making it possible to deploy them in large numbers in a wide range of
        applications. For example, in smart homes, IoT sensors can be used to monitor the temperature, humidity, and lighting
        conditions in different rooms and adjust them automatically based on user preferences. In agriculture, IoT sensors
        can be used to monitor soil moisture levels and weather conditions and automatically control irrigation systems to
        optimize crop growth.

        IoT sensors can be connected to a range of network technologies, including Wi-Fi, cellular, and satellite networks. This
        enables them to transmit data to a central server or cloud-based platform, where it can be analyzed and used to make
        decisions and take actions in real-time. Here are some of the types of sensors commonly used in IoT:



        1.   Temperature  sensors  measure  temperature  and  are  used  in  heating,  ventilating,  and  air
            conditioning (HVAC) systems, smart homes, and weather monitoring systems.



                           2.   Humidity  sensors  measure  humidity  and  are  used  in  HVAC  systems,  smart  homes,  and
                              weather monitoring systems.




        3.  Light sensors - detect light and are used in smart lighting systems and outdoor lighting
            systems.



                           4.   Pressure sensors measure pressure and are used in industrial control systems, automotive
                               applications, and building automation systems.





        5.  Proximity sensors detect the presence or absence of nearby objects and are used in
            manufacturing, security systems, and robotics.





                           6.   Accelerometers measure acceleration and are used in fitness trackers, smartwatches, and
                              automotive applications.



        7.   Gyroscopes measure angular velocity and are used in navigation systems, robotics, and
            virtual reality systems.



                           8.   GPS sensors  detect  the  location  and  are  used  in  navigation  systems,  fleet  management
                              systems, and asset tracking systems.
