COMMANDS
Get Emissivity Setting [0x86]
After this command is sent, the sensor will return the emissivity setting as a floating point value as
follows:
Value No value is sent. The sensor will return the emissivity setting.

Command ID Send the command with these bytes empty.
The sensor will return the emissivity setting in
these bytes as a floating-point value.
After the following commands are sent, the sensor will send back the same data as an “echo” to
confirm it was received:
