I found time over the holidays to mess with one of my old original projects- the Tri-Temp
It was very interesting to poke around in some of my original hardware/code and add some things to it.
Attached is a gallery of pics from the latest incarnation.
I’ll add the code changes and an updated schematic shortly. Continue reading “Tri-Temp Update”
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!
This is the first version of the Tri-Temp code. If you find any errors or add any features let me know so I can update it. Continue reading “Tri-Temp Standard Code v1.0”
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.
I hacked this DHT11 together today to show the outside temp/humidity. I normally test output to the Serial port but this time I did LCD and serial. The clear case is a case from Maker Shed. Eventually all this will fit inside the box but until I’m satisfied I’m gonna let it hang…
Below is the code. I added the Dew Point in F.

This was my first sensor. It’s a digital temperature and humidity sensor. It uses three pins, two for power and one for data. It worked perfectly…except….the libraries provided by Virtuabotix ($9.99 via Amazon.com) didn’t work with the Arduino IDE v1.0.
So if fixed it!
