MPX4250DP Pressure / Depth Sensor
Posted: Oct 20th, 2014, 12:22 pm
I am using MPX4250DP as pressure/ depth sensor in my ROV.
I don't know the precision (resolution) of the sensor in terms of pressure and depth.
According to the resolution of Arduino UNO ADC (0 - 1024) and scale of sensor output (0 - 5 V) the pressure would be in step of ~0.24 kPa and depth in step of ~2.5 cm.
Are my calculations correct?
Is there any way to increase the resolution of the output?
My ROV will go to maximum depth of 10 m.
In the datasheet, there is a figure for power supply decoupling and output filtering. Is this necessary to implement?
