The OSL I2C pressure level uses the I2C protocol to output level readings. Coupled with the Code examples provided integration is simplified by avoiding analogue circuitry with a digital interface.  code examples and full support are included.

I2C Pressure sensor read 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.
