Protocols and Sensor
Sensors are a very important component of IoT Systems.
Sensors are minute, smart and cheap!
The selection of sensors depends on the purpose you wish to achieve.
You may want the sensor to be able to detect motion, temperature, pressure, smoke or any other such trigger.
The choice of sensors also depends on their accuracy, reliability of results, the range at which they should work, resolution and level of intelligence which in other words means their ability to deal with noise and interference.
Once the data has been collected by the sensors, it requires a medium for transport.
In other words, a communication channel is necessary between sensors and the cloud.
IoT protocols are responsible for transferring data in the online world and this transmission can only be possible if two devices are safely connected.
IoT standards and protocols involve an invisible language allowing physical objects to communicate with one another.
Incoming, raw data from the sensors must pass through gateways to reach the cloud.
Gateways translate network protocols ensuring seamless communication of all devices within the network.
