MCP9808 High Accuracy I2C Temperature Sensor Breakout Board

This I2C digital temperature sensor stands out as one of the most accurate and precise sensors we've ever come across. It offers a typical accuracy of ±0.25°C within the -40°C to +125°C range and a precision of +0.0625°C. It's highly compatible with any microcontroller using standard I2C. With 3 address pins, you can connect up to 8 sensors to a single I2C bus without address collisions. What's more, its wide voltage range from 2.7V to 5.5V makes it suitable for various logic systems. Unlike the DS18B20, this sensor comes on a breakout board PCB for easy use. The PCB has mounting holes and pull - down resistors for the 3 address pins. We've also provided a great tutorial and library for Arduino or CircuitPython, so you can get up and running in 15 minutes or less. Key specs include simple I2C control, adjustable address pins for up to 8 sensors on a single bus, 0.25°C typical precision from -40°C to 125°C (0.5°C max guaranteed from -20°C to 100°C), 0.0625°C resolution, 2.7V - 5.5V power and logic voltage range, and a typical operating current of 200 μA.

Using this MCP9808 temperature sensor breakout board is a breeze. First, connect it to your microcontroller using the standard I2C interface. You can adjust the address pins according to your needs, allowing you to connect up to 8 sensors on a single I2C bus. Power it up with a voltage between 2.7V and 5.5V. Once connected, you can use the provided tutorial and library for Arduino or CircuitPython to quickly start getting temperature readings. When it comes to maintenance, keep the board clean and dry. Avoid exposing it to extreme temperatures outside its specified range. If you notice any issues, check the connections and make sure the power supply is stable. Also, refer to the datasheet for more in - depth troubleshooting.
