A-2 Millennial Net
Application Overview
Millennial Net includes a sample application in the RK-5409-5 Reference Kit. This application
demonstrates a real-world application of Millennial Net's end node peripheral interface and
how it is used for monitoring and data collection purposes across a wireless network.
The RK-5409-5 Reference 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 ±5%
accuracy.
The sensor's resistance change is measured via voltage change, measured by an end node's
ADC channel 0, and converted by the TempMonitor application software (included with kit) to
temperature. The sensor connection diagram is shown in
Figure A-1 and process flow is shown
in Figure 2.
