The MCP9808 is perhaps one of the most accurate temperature sensors we have seen. This device offers an incredible ±0.25 of accuracy over an extended temperature range of -40°C to +125°C.


The MCP9808 has an industry standard 400 kHz, 2-wire, SMBus/I2C compatible serial interface. These features make the MCP9808 ideal for sophisticated, multi-zone, temperature-monitoring applications including:

  • industrial freezers and refrigerators
  • food processing
  • personal computers and servers
  • consumer electronics
  • handheld/portable devices

All I2C Mini Modules are designed to operate at 5VDC. Using a convenient 4-Pin plug, devices can be daisy-chained onto the I2C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application.

Pull-up resistors are included with all dcubestore.com master devices. If you are wiring in your own I2C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.

All I2C Mini Modules include a I2C Cable.


This is a general purpose I2C device compatible with all computing platforms, including Raspberry Pi, BeagleBone, Arduino, Particle, Onion Omega, BridgeX5, and many more. All dcubestore.com devices support a strict +5V I2C Bus standard.
