I'm trying to use the MPX5010DP sensor as a water level sensor and I'm running into a difficulty. (This is not my area of expertise needless to say).
I have a 5V supply attached to Pin 3 (Vs) and the Ground connected to Pin 2. I am reading the output from Pin 1 (Vout) and Pin 2 with the multimeter and it is very obviously not responding to changes in pressure across the barbs of the sensor. I'm getting a reading of around 850mV that declines slowly over time.
What have I done wrong? Many thanks for any assistance.
