Description

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.

User-Selectable Measurement Resolution: - +0.5°C, +0.25°C, +0.125°C, +0.0625°C offer Accuracy of - ±0.25 (typical) from -40°C to +125°C - ±0.5°C (maximum) from -20°C to 100°C - ±1°C (maximum) from -40°C to +125°C.

This sensor has an industry standard 400 kHz, 2-wire, SMBus/I2C compatible serial interface, allowing up to 8 to be controlled with a single serial bus. 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 and
  • handheld/portable devices.

Mini Modules

Our mini modules provide a standardized footprint to simplify the design of your project, and allow for a smaller form factor without sacrificing the plug-and-play  ease of use that our product line affords.

All I²C Mini Modules are designed to operate at 5VDC. Using a convenient quick connect 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 ControlEverything.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 mini modules are 50.8 x 31.75 mm.
