Temperature is represented as a 16-bit, unsigned integer number. The lowest number in the

Temperature Data Register is 0x0000 (0 in Decimal) and the highest number is 0xFFFF (65535

However, the temperature sensor accuracy is defined within the temperature compensation

An example of Temperature conversion:

Temperature Register Byte [0] = 0x84

Temperature Register Byte [1] = 0x32

Each ESRF-ESF sensor is uniquely identified by a 32-bit serial number. This number can be

read from the Serial Number Register and is 4 bytes long.

An example of a serial number conversion:

Serial No Register Byte [0] = 0x01

Serial No Register Byte [1] = 0x05

Serial No Register Byte [2] = 0x62

Serial No Register Byte [3] = 0x1F

The serial number 0x0105621F corresponds to 17130015 in decimal.
