16 Registers
This section describes the registers of the ENS160 which enable the host system to
• Identify the Device and version information
• Configure the ENS160 and set the operating mode
• Read back STATUS information, the calculated gas concentrations and Air Quality
Indices
16.1 Register Overview
Note that some registers are spread over multiple addresses. For example, PART_ID at
address 0 is spread over 2  is 2). Registers are stored in little endian so
the LSB of PART_ID is at address 0 and the MSB of PART_ID is at address 1.
