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 micro controller 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 it 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.

Simple I2C control
Up to 8 on a single I2C bus with adjustable address pins
0.25°C typical precision over -40°C to 125°C range (0.5°C guaranteed max from -20°C to 100°C)
0.0625°C resolution
2.7V to 5.5V power and logic voltage range
Operating Current: 200 μA (typical)

How do I connect and use this I2C sensor with a microcontroller?

It communicates over I2C. Connect Vcc in the 2.7 to 5.5 V range, GND, and the SDA and SCL lines to your microcontroller. The breakout board includes pull down resistors for the 3 address pins to simplify addressing.

What is the temperature range and accuracy of the sensor?

The sensor operates from -40 C to 125 C. It has a typical accuracy of 0.25 C and a resolution of 0.0625 C. The accuracy is guaranteed to 0.5 C from -20 C to 100 C.

How many devices can be connected on a single I2C bus and how are addresses set?

Up to 8 devices can be on one I2C bus. Three address pins allow eight distinct addresses, and the breakout provides pull down resistors to set them.

How does this sensor differ from the DS18B20?

This device uses the I2C interface and ships on a breakout board for easy use. Unlike the DS18B20, it is not a through hole package.

What are the power and current requirements for operation?

Power and logic voltage range is 2.7 V to 5.5 V. Typical operating current is 200 microamps.
