Thank you Lefty,i want to try with the Wheatstone bridge. I'm following the notation from wikipedia : http://en.wikipedia.org/wiki/Wheatstone_bridgeIn this page there is the formula to calculate the voltage (Vg) that depends on Vsupply and the 4 resistor values. Following the schematics, Vg is the voltage between pin 2 (+out 2) and pin 5 (-out 3)....right?The datasheet says that the sensor span is 80 mV, does it means that Vg(max) is 80 mV? Thanks again!
Did anyone get this to work?
Anyone know the maximum pressure of this? I know datasheet say 150kpa but its not enough for divelogger (15m maximum depth)... unfortunately diveduino project is dead and i2c sensor is expensive to play ...
Something wrong with my circuit or this sensor is bad?
If datasheet say 80mV so the difference must be about 80mV by maximum pressure not 2,5V constant without any dependence on pressure... (with 3V power is 1,5V constant ... this mean half power voltage like dividing resistance....)....
