Technical background: 

 
The  philosophy  behind  Edu-Logger’s  plug  and  play 
technology is based on each sensor’s ability to store its 
own  data  due  to  an  internal  flash  memory  chip  and 
micro-controller  in  each  plastic  Edu-Logger  body.  
This  technology  allows  the  sensor  to  collect  and  then 
store the digital data in the correct scientific units (

o

C, 

o

F, Lux, %, ppm, for example). 

 
The sensor is pre-calibrated at the factory. The built-in 
software  in  the  logger  can  be  upgraded  at  any  time 
using software. 
 

The  pressure  sensor  uses  the

 piezoresistive 

effect. 

The transducer is based on silicon between metal foils 
that  changes  its  resistance  according  to  pressure.  One 
side  of  it  is  at  complete  vacuum  that  enables  to 
measure the absolute pressure on its other side. 
 
This  transducer  is  built  as  a  strain  gauge  with 
Wheatstone  bridge  circuit  so  its  output  is  a  voltage 
depends on it absolute pressure. 
 
When the user inhales, a pressure is applied directly to 
the blood pressure monitor cuff’s bladder and detected
