INTRODUCTION
This evaluation board is designed to provide a fast and easy start for evaluation of the GSS CozIR®-
LP3 sensor. The evaluation board brings several interfaces and interconnections shown in Figure 1.
The CozIR®-LP3 Evaluation Board is designed to allow the user to evaluate all the hardware and
software functions of the sensor. This manual provides information about the board’s
interconnections, jumper settings, communications, and debug interfaces.
The sensor can be controlled by a PC application via the USB interface, or standalone and controlled
externally via connections to the sensor on the evaluation board.
The sensor and other supporting electronics can be evaluated using a PC software application. This
provides the user with a graphical user interface to all the main functions of the sensor, as well as a
terminal mode, allowing the user to write and read data directly from the sensor registers.
As well as evaluating the CO
2
sensor, the software application allows the user to monitor and store
other environmental conditions such as pressure, relative humidity and temperature.
The evaluation board also has the capability to measure the current consumption of the sensor in
any of its operating modes, allowing the use to accurately assess real world power use over time.
Alternatively, the sensor can be completely separated from all the other electronics on the
evaluation board and controlled directly by the user via edge connectors. All data, control and GPIO
pins of the sensor can be connected to connectors, J3, J4 and J5. Power is provided via a separate
edge power connector (J2), via USB (J1), or directly via header (J5).
