LCC Requirements

The Lizard Climate Control system has these requirements (updated as they change):

  • turn lights and heaters on/off at specified times
  • maintain specified temperatures during day and night
  • report current temperature/humidity both locally (at cage) and remotely via internet
  • manual bypass of Arduino control of AC switches
  • built in fail-safe for over temperature situations
  • protect sensors from lizard and other in-cage hazards
  • visual indication of temperature situation (green=good, red=bad etc)
  • document it!

 

Tri-Temp Project Intro

Description

This is the Tri-Temp project. It comes in two flavors- Standard and Ethernet. The Standard version outputs all readings on an LCD. The Ethernet adds output to HTML via a web browser. I did not design this to use an Ethernet shield- only the Arduino Ethernet- it’s more compact.So what’s this all about? Reading the Temp and Humidity! Nothing special going on here, just reading the digital data from three DHT22 sensors and displaying it.

Tri-Temp project

Coming soon- the mostly completed Tri-Temp box. Two editions- Standard and Ethernet. I’m still finishing it up and have lots of pictures.

  • Measure temperature and humidity from three locations via digital probes
  • Self contained in a small project box
  • Standard uses Arduino UNO
  • Ethernet uses Arduino Ethernet
  • Uses 16×2 LCD to display on Standard version
  • Ethernet uses LCD plus web interface!
  • LCD interfaces with Arduino via serial- no hogging all the digital lines!
  • It has its own logo!
  • Internal temp monitoring….just because
  • 3 wire External digital probes are pluggable and cheap!
  • Runs on 9v battery (don’t know how long yet….)
  • 4 interface buttons on project box to control the display

I should have it wrapped up and posted soon. The code will no doubt be a constant work in  progress but the hardware is almost complete.
