Information Transduction and Encoding

How can physical stimuli be transformed into digital data and vice versa?


IoT devices need to be able to share digital information about physical objects of interest. However, physical objects provide physical stimuli, which is not compatible with the format of telemetry data that devices need to transmit.


The IoT device can be used as an interface to the physical world and is equipped with the ability to transduce physical stimuli into digital data, and vice versa.


Physical stimuli is converted into analog data and consecutively into digital measurement packets. The sensor and/or actuator mechanisms can be used to carry out this task.


Actuator, Sensor







The smoke detector device contains a sensor mechanism that uses an analog-to-digital converter to convert the physical stimuli to telemetry data that is transmitted by the device’s modem.
