Design & Implementation of Automation System using IoT with DragonBoard 410C

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Definition of Keyterms

Internet of Things (IoT)
Dragon­Board 410c
DC Motors
Connecting Wires

In this applic­ation, we are interested in designing an automation system using IoT so as to control small applic­ations of home such as switching of AC, Fan, Pumping Motor, etc. For this purpose, we can make use of the processor depending upon the need of the applic­ation i.e. a MCU (ESP series) and even the Dragon­Board can also be used.

Control Logic Develo­pment

Control Logic
if then elseif
Dominant Parameter
Next step to develop the control logic so as to operate the appliances effect­ively by itself so as to provide a fully functional system

For AC & Fan

We can use the temper­ature of the room as the deciding parameter with the help of set points

Procedure Steps

Set Point
Proc­edural Steps:
In this discus­sion, we need to elaborate the various task involved in this applic­ation using the basic concepts of the IoT i.e.
1) We have to target the load required to be controlled by this applic­ation i.e.
Operation of the Air Condit­ioner
Operation of Pumping Motor
Operation of Fan

Progra­mming & Logic Develo­pment

Dominant Parameter
In this discus­sion, we are going to discuss about the progra­mming tool that will be employed in this applic­ation. Here we are interested in operating the Fan, AC and Pumping Motor. So this target can be easily achieved simply by using C language with if then elseif logic

Specif­ication Sheet

Inform­ation of Hardware
We need to find the specif­ication of these load i.e. the most dominant parameters say, current, power, etc.

Pumping Motor
Power: 2.5 KW, Current: 05 Ampere

Similarly, we can find the parameters of the other two applia­nces.

Implem­ent­ation of the circuit

Bread Board
Connecting wires
Rail of Supply & Ground
We will make the connection on the breadboard using all the components an devices.
For this purpose, we should make all the connection with the supply voltage, ground and other sensor input and output so as to drive the applic­ations effect­ively.

Discussion of the system using IoT

In this concluding section, we had finally implem­ented a fully function system which simply operate as per the rules designed depending upon the set point of the temper­ature. This logic can also operate on the basis of the inform­ation read from the sensor primarily, in case of the pumping motor.
