I’ve always been fascinated with the history of computers. Who invented the first one? What was their first design? Why did people want a computer? When were computers first invented? I am going to attempt to tie the current generation of microcontrollers, such as the NXP LPC1756, back to the first ...

Hi LLoyd, NP. Let's say the barometric pressure is 1000 mBar and O2 is 20%.Then the partial pressure of O2 would be 200 mBar (1000 mBar times 20%.) Now decrease the barometric pressure to 750 mBar (about the cabin pressure in an unpressurized airplane at 7500 feet MSL) then the paritial pressure of ...

Purpose: Develop the ability to monitor oxygen partial pressure in a sealed container in order to monitor an anaerobic process. Components: SuperPro and LuminOx 2 oxygen sensor http://sstsensing.com/application-note-electronic-sensor/luminox-sensor The LuminOx 2 oxygen sensor has an on-board ARM pro...
