hello there,
I just bought a MPX 4115A absolute pressure sensor and to test it I used a very simple code:
the w0 readings are very erratic and change at each reading. The data sheet does not specify if a resistor load is necessary and if I use a 4.7 KOhm resistor to the positive supply I get a reading of 1023. This may indicate that the output of the sensor (pin 4) is floating and therefore the sensor looks to be defective.
Am I doing something wrong or should I replace the sensor?
Thanks

Code:
#Picaxe 08M2
#Terminal 4800
#No_Data
do
readadc10 c.4,w0
debug
pause 500
loop

Thanks
