Prototyping
• Plan to make simple breakout board with
MAX233 and line coupling components to
interface PC directly with XBee module and
SPIM.
• Test basic functionality and config
• Aide software development
Power System – Specifications
• Wide load variation regulated supply
– 3.3V Load Variation 52 mA to 402 mA
– 12 V Load Variation 50 mA to 260 mA
• Uninterrupted operation (All modules)
– High efficiency 3200mAh Li-Ion battery
– Integrated inline charger
• Worst case efficiency is 50%
Power System – Block Diagram
Sensor - Types
• Motion Sensor
– Powered from single 3.3 V supply.
– Produces an interrupt.
• Cell Phone Detector
– Powered from single 3.3 V Supply.
– Produces a V/dB output of the power level
• Temperature Sensor
– Located on sensor I/F board
– Data taken transferred serially over SPI interface.
Sensor – Interface Features
