Adafruit MCP9808 High Accuracy I2C Temperature Sensor Breakout Board

Key Features:

• High Accuracy I2C Temperature Sensor Breakout Board
• i2c digital interface
• More accurate/precise with a typical accuracy of about 0.25 degC
• 3 address pins so you can connect up to 8 to a single I2C bus without address collisions
• Wide voltage range makes is usable with 2.7V to 5.5V logic

This I2C digital temperature sensor is one of the more accurate/precise we' ve ever seen, with a typical accuracy of ± 0.25 °C over the sensor' s -40°C to +125°C range and precision of + 0.0625 °C. They work great with any microcontroller using standard i2c. There are 3 address pins so you can connect up to 8 to a single I2C bus without address collisions. Best of all, a wide voltage range makes is usable with 2.7V to 5.5V logic!

Unlike the DS18B20, this sensor does not come in through-hole package so we placed this small sensor on a breakout board PCB for easy use. The PCB includes mounting holes, and pull down resistors for the 3 address pins. We even wrote a lovely little tutorial and library that will work with any Arduino compatible. You' ll be up and running in 15 minutes or less.
