| MCP9808 Temperature Sensor |
| ########################## |
| |
| Overview |
| ======== |
| |
| Sample application that periodically reads temperature from the MCP9808 sensor. |
| |
| The MCP9808 digital temperature sensor converts temperatures between -20°C and |
| +100°C to a digital word with ±0.5°C (max.) accuracy. It is I2C compatible and |
| supports up to 16 devices on the bus. We do not require pullup resistors on the |
| data or clock signals as they are already installed on the breakout board. |
| |
| The MCP9808 is available in a discrete component form but it is much easier to |
| use it mounted on a breakout board. We used the Adafruit breakout board. |
| |
| In this hookup we are only connecting one device to one of the supported boards. |
| It reads the temperature and displays it on the console. |
| |
| Software |
| ======== |
| |
| This sample uses the Zephyr sensor APIs and the provided driver for the MCP9808 |
| sensor. |
| |
| Pinouts |
| ======= |
| |
| The MCP9808 requires 2 wires for the I2C bus plus power and ground. The power |
| can be either 5V or 3.3V. |
| |
| We connect the Data and clock wires to Analog ports A4 and A5 which is the I2C |
| pins on Arduino compatible boards. |
