Application Overview
Millennial Net includes a sample application in the EK-5209-5 Evaluation Kit. This application
demonstrates a real-world application of the Millennial Net's endpoint peripheral interface and
how it is used for monitoring and data collection purposes across a wireless network.
The EK-5209-5 Evaluation Kit includes a temperature sensor assembly with a 10,000 Ohm Kele
sensor (Type 3) that changes resistance as its environmental temperature changes. The sensor
can be used to measure temperatures from -35
O
to +240
O
degrees Fahrenheit, with precision of
5%.
The sensor's resistance change is measured via voltage change, measured by an endpoint's
ADC channel 0, and converted by the TempMonitor application software (included with kit) to
temperature. The sensor connection diagram is shown in Figure B-1 and process flow is shown
in Figure 2.
