The MCP9800 Temperature Sensor SEEVAL® 32 Data Logger board (MCP9800DM-DL2) is a PCB assembly that uses a PIC10F202 to read Temperature Data using I2C communication from a Microchip MCP9800 Temperature Sensor, and stores that data, also using I2C communication, to a 24LC16B Serial EEPROM. The board can then be placed into a SEEVAL®32 Serial EEPROM Evaluation tool and the content can be read and stored into a .hex file. Microchip also provided an Excel Spreadsheet that can be used to import the .hex file so that the data may be graphed on your computer screen.

The MCP9800 is a digital temperature sensor capable of reading temperatures from -55°C to +125°C. Temperature data is measured from an integrated temperature sensor and converted to digital word with a user selectable 9 to 12-bit Sigma Delta Analog to Digital Converter. The MCP9800 notifies the host controller when the ambient temperature exceeds a user programmed set point. The ALERT output is programmable as either a simple comparator for thermostat operation or as a temperature event interrupt. Communication with the sensor is accomplished via a two-wire bus that is compatible with industry standard protocols. This permits reading the current temperature, programming the set point and hysteresis and configuring the device.
