Description
The I2C pressure sensor uses a multiple registers containing pressure and level data accessible via I2C . When all the fixed parameters are determined e.g. pressure range , the real time 24 bit ADC reading is then read , that with the fixed paratmers is then used to calcualtre the pressruee see example below
The I2C clock speed will vary depending on the length of cable.
This type of pressure sensor is ideal for Raspberry Pi , Arduino and Embedded systems.
I2C Pressure sensor reading example
Below is an example of a 0 to 10 Bar absolute pressure range, the NVM would look like this:
- 2A (Zero pressure range) = 0000
- 2B (Zero decimal place) = 0000
- 2C (Full scale pressure range) = 000A (10 decimal)
- 2D (Full scale decimal place) = 0000
- 29 (Pressure engineering units) = 0002
- 2E (Pressure datum type) = 0001
An example of typical calibration figures would look something like this:
- 24 (Zero calibration LSB) = 4563
- 25 (Zero calibration MSB) = 0019
- When converted from HEX, 0019 4563 to decimal = 1656163
- 26 (Full scale LSB) = 4C8E
- 27 (Full scale MSB) = 00E6
- When converted from HEX, 00E6 4C8E to decimal = 15092878
For example 0 Bar Absolute pressure = 1656163 and 10 Bar absolute pressure = 15092878 giving a span of 13436715 for 10 bar.
