The MCP9808 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. With three address jumpers on the back, you can connect up to 8 to a single I2C bus without address collisions. Best of all, a wide voltage range makes it usable with 2.7V to 5.5V logic! Unlike the DS18B20, this sensor does not come in through-hole package so Adafruit placed this small sensor on a breakout board PCB for easy use. The PCB incl
