The Arduino Climate Sensor Project

2010 Nathan Oostendorp

This is one of those sketches that I kind of assumed was out there already, but when I couldn't find it I just hacked it up. I am using this as part of a greenhouse environment monitoring project, where I want to log temperature and humidity to a computer, as well as display on an LCD.

It is largely plagiarized from Maurice Ribble example temperature code, and sparkfun wiring example for the SHT15 breakout board http://wiring.org.co/learning/basics/humiditytemperaturesht15.html

LCD code plucked from LCD117demo2x16 for arduino
http://www.moderndevice.com/products/16x2lcd-lcd117kit

Components:

• SHT15 breakout board from sparkfun http://www.sparkfun.com/commerce/product_info.php?products_id=8257
• LCD and TTL serial driver board http://www.moderndevice.com/products/16x2lcd-lcd117kit
• Arduino compatable board (RBBB kit pictured http://www.moderndevice.com/products/rbbb-kit )

Basic Circuit:

• +5v -> SHT VCC
• dataPin -> SHT DATA
• clockPin -> SHT15 SCK
• Gnd -> SHT15 GND
• +5v and Gnd to TTL serial driver board 5v and G
• txPin to TTL serial driver board RX

Instructions:

• assemble as above
• check out source code from Git
• tweak pin assignments, and upload to the arduino.
• to log data, keep connected to a computer and dump serial output to file
