This document introduces the features of the ADuC824-Based Temperature-Logger product, including battery power supply, precise temperature measurement, data storage, and data upload.
This document describes a battery-powered temperature logger built using the ADuC824 MicroConverter. The device logs precise temperature readings every 10 minutes to on-chip non-volatile Flash/EE memory, storing up to 23 hours of data for later upload to a PC. It utilizes a precision RTD connected directly to the ADC front-end, eliminating the need for external signal conditioning circuitry. To conserve power, the unit enters a powerdown mode between conversions during logging.
The unit logs a precise temperature reading every 10 minutes.
The device stores the last 23 hours of temperature readings for upload to a PC.
