Here I am, bored with so much paperwork to do during the winter break that I decided to go back in time a little bit and work with hardware again. OK, it is not REALLY “working with hardware”, but at least I can remember good old times when I was riding a train for 2 hours in Tokyo in order to get to work.
Enough talking, I decided to build up a sensor for my university’s computer labs. It is pretty annoying that everyday someone from the administration comes to me complaining about lights that were left on or about the air-conditioning system’s temperature.
So here comes the Arduino to the rescue.
Arduino is a open hardware platform targeted to be used by beginners (here I am). My primary objective is to check whenever the room lights are on, if the air-con temperature is inadequate and also (as a bonus) the humidity in the room.
The parts I’ve used are listed below:
- Arduino Ethernet W/O PoE + USB2SERIAL
- Grove – Base Shield
- Grove – Temp&Humi Sensor
- Grove – Light Sensor
