The temp sensor is a joint project between Liquidware and Modern Device and is available here as an assembled module. Thanks! -JustinThe Temp Sensor for Arduino is the first project of a joint Modern Device-Liquidware collaboration. It?�s capable of turning the Arduino into an instant thermometer, plugging directly into Arduino Duemilanove Analog Pins 2-5.
The TMP421 chip is a 12 bit I2C chip that works from minus ??40 to 125 degrees C, so the sensor is able to resolve .04 degrees C per bit. The absolute accuracy is guaranteed to be +/- 1 degree C. The relative resolution should make the sensor useful for a range of higher resolution activities such as sniffing out drafts around windows.
The Temp Sensor comes with a 4-pin male header (unsoldered) and 8 total pin-outs to allow for maximal flexibility in project use. With a small, narrow form factor, it?�s easy to set up multiple Temp Sensors for local temperature monitoring as well.
A ready-to-go Arduino library is also available free for download at the Liquidware App Store for full, off-the-shelf integration with any Arduino project.
The chip communicates via I2C and also has an onboard remote temperature sensing capability as well.
