Week 2 Final Year Project 2

Date: 31 January 2018

Time: 3.00 p.m

Place: Library UniKL BMI

Objective: 

- To find the circuit simulation of the humidity and temperature DHT22 sensor in the Proteus using the Arduino Uno before construct on the real hardware.

Activities: 

- Today, I find the circuit construction for the simulation of humidity and temperature DHT22 sensor. It should be added their libraries to the simulation program. After adding the library and realization the wiring diagram, the written code is loaded into the development environment. 

- The DHT22 pin no 2 is connected to the pin no 2 of the Arduino Uno as the data collected. While pin no 1 for the supply 5V and pin no 3 connected to the ground. I have used the program Proteus software to simulate and to evaluate the design's feasibility and stability. Temperature and humidity simulating system were designing by Proteus software.

- The Arduino Uno was used to control the whole system. The humidity and temperature sensor DHT22 were used as the data collector. The system compare the collecting temperature and humidity data with their normal value to decide whether modifying the temperature and humidity or not.
