The PCD: Portable & user friendly Low-priced Versatile & multi-purposed Measure and display results instantly Store data for later re-evaluation Control over environment Customization and extension of feature-set in HW & SW

Project goalsSelf-learning process: Data sheets, schematics, HW & SW, MPLab Assemble & HW debugSensors debug and driver implementationMultiple devices production 9 boardsBoxes productionMain menu improvementBOM & inventory management

Main MenuPCD voltage shows battery value.Dcdc opens automatically when needed. Dcdc and all related sensors turn off when temperature sensor is on.Each menu has different sensors according to what is assembled on its board.

AccelerometerA micro-machined device measuring static acceleration.Output voltage alternates according to 3 dimensional axis.

PressureA silicon sensor measuring absolute pressure.Output voltage can be converted to

pressure by:
