# mcp9808-sensor [<img src="https://cdn-shop.adafruit.com/1200x900/1782-00.jpg" width="150" align="right">](https://www.adafruit.com/product/1782) Welcome to mcp9808-sensor, a Node.js I2C module for the Microchip MCP98089 digital thermometer. Adafruit sells a [MCP9808 breakout board](https://www.adafruit.com/product/1782) and [here is the datasheet](http://ww1.microchip.com/downloads/en/DeviceDoc/25095A.pdf). This module uses [i2c-bus](https://github.com/fivdi/i2c-bus) which should provide access with Node.js on Linux boards like the Raspberry Pi Zero, 1, 2, or 3, BeagleBone, BeagleBone Black, or Intel Edison. ## I2C Address The default I2C address is ```0x18```. You can change the address by tying a conbination of the ```A0 A1 A2``` pins to VDD. Each pin of the ```A0 A1 A2``` set adds an offset to the base address of ```0x18``` | Pin | Offset | |---|---| | ```A0``` | ```1``` | | ```A1``` | ```2``` | | ```A2``` | ```4``` |
