2. Describe the role of sensors in IoT. Explain different types of sensors and
their applications with examples.
Sensor
Sensors are used for sensing things and devices etc.
A device that provides a usable output in response to a specified measurement.
The sensor attains a physical parameter and converts it into a signal suitable for
processing (e.g. electrical, mechanical, optical) the characteristics of any device or
material
to detect the presence of a particular physical quantity.
The output of the sensor is a signal which is converted to a human-readable form
like
changes in characteristics, changes in resistance, capacitance, impedance, etc.
An IoT sensor is any sort of mechanism or tool, such as a camera or air quality
monitor, integrated into a device. These sensors gather information — like
water levels, air temperature and traffic patterns — related to the
environments in which they’re deployed and transmit it to the cloud via Wi-Fi,
bluetooth, 5G or other mobile network.

Take smart thermostats, for instance, which are equipped with temperature
sensors that measure fluctuations in a home’s temperature. Because these
thermostats are connected to the internet, users can log in via an app to
monitor the temperature of their home and control the thermostat remotely.
IoT Sensors

IoT sensors gather information so devices can be used remotely and data
can be shared in real time. The data gathered by IoT sensors and sent to
the cloud is analyzed by software that can make sense of the information
and then sent to users. This data is used to track trends and gather
insights about everything from efficiency and energy use in factories to
athletic performance and a user’s health.
