To calibrate we used the following parameters:
Voltage range that the sensor can output(From the datasheet) = (0.5 – 4.5 )V
Microcontroller maps these within a range of 4096 values.
Minimum Pressure (Pmin) gets mapped onto -> (0.5 * 4096)/ 5 = 409.6
Max Pressure (Pmax) gets mapped onto -> (4.5 * 4096)/5 = 3686.4
Pressure range(Prange) the pressure sensor can read is 1.2MPa
Actual Pressure Read = ((𝑷𝒓𝒆𝒂𝒅𝒊𝒏𝒈 −𝑷𝒎𝒊𝒏)/(𝑷𝒎𝒂𝒙 −𝑷𝒎𝒊𝒏)) * Prange
