Quick overview of sensor modules 2006-10-01

Each sensor module will be smart due to the inclusion of it's own microcontroller. My current plans are to build each module around a low-power 32-bit ARM7 based microcontroller.

A suitable device can be selected from the Analog Devices ADuC700 Series, these are ARM7TDM1 based cores with integrated data converters which include a range to devices with multiple analog and digital inputs and outputs.

For the initial prototyping I'm going to use an ADuC7020 Evaluation Board which is available from Analog Devices for only 30 USD (EVAL-ADUC7020MK).

The ADuC7020 has a 5 analog-to-digital converter (ADC) input channels, 4 digital-to-analog converter (DAC) output channels, and 14 general purpose input/output (GPIO) pins.

I'll try to provide more information next time.
