This guide will show you how to build the circuit and write the program to build your own Arduino Temp / Humidity monitor that can be viewed via LCD display, webpage and SNMP.
It is important that you have a working knowledge of the Arduino, networking and basic programming.
Here are the pieces needed for this project:
Arduino UNO
Netshield
MakerShield with Breadboard
Sensors
Wires
Serial LCD Screen
Add the Netshield to the Arduino.
Solder custom header pins to use as a spacer for the MakerShield.
Using long-pin male headers and long-pin female headers solder them as shown.
These custom headers will be used as spacers between the Netshield and the MakerShield.
NOTE: The center pin on the longer spacer will not be used. I left it to make the unit stronger.
Add the spacers.
Add the MakerShield.
As you can see, the spacers give plenty of room and prevent grounding issues.
Add custom wires to breadboard.
Add sensors.
Add code to the Arduino.
A PDF of the sketch is included with this project.
