The MCP9800 Temperature Data Logger Demo Board allows user to store up to 128000 temperature readings from the MCP9800 sensor to the 24LC1025, Microchip’s 1024Kbit EEPROM. The PIC16F684 PICmicro® Microcontroller communicates with the sensor and EEPROM. In addition, the PICmicro® interfaces to a PC using the PICkit™ 1 Flash Starter Kit and transfers the temperature readings from the EEPROM to the PC. Microsoft Excel can be used to view the data. The PICkit™ 1 Flash Starter Kit can also be used to reprogram the onboard PICmicro®. The user can specify number of measurements and measurement duration.
The MCP9800 Temperature Data Logger Demo Board can be powered using an external supply, the PICkit™ 1 Flash Starter Kit, or a 24 mm Lithium Battery. The battery allows for stand-alone operations.
