The Thermopile CO2 Detector Evaluation Kit (EVK)
provides an easy way to evaluate the RTD120D dual-
channel thermopile in a CO2 gas detector application.
It operates stand-alone or with a PC running CO2
Detector Evaluation Software, making the CO2
concentration and intermediate data available for
plotting, logging, processing, exporting and analysis
using software available. The software and user
manual for the kit can be downloaded from:
www.renesas.com/rtd120d-evk.

Introduction
The Thermopile CO2 Detector Evaluation Kit is
designed for evaluation of the Renesas’ RTD120D
dual thermopile in a CO2 gas sensing application,
such as to detect the ambient CO2 concentration. It
has a NDIR (Non-Dispersive Infrared) thermopile-
based gas sensing circuit and the concentration of
CO2 gas is measured based on the intensity of the
NDIR radiation.
It can be used as an application example to illustrate
how the thermopile, in combination with other
Renesas components, can be used to implement a
CO2 detection and concentration measurement
system.
Getting Started
Right out of the box, the EVK can begin measuring
CO2 levels right away:
1. Attach the LCD module to the main EVK board
2. Remove the two shorting jumpers from the MODE
and RESET headers on the main board. Save
these for use when flashing new versions of
firmware to the kit.
3. Connect the provided USB cable to the board and
to a power source, such as a phone charger or a
PC USB port.
Two splash screens will be displayed in sequence,
identifying the EVK, its software version and serial
number. Then after a 30 seconds warm-up period
(“CO2 WARM”), the CO2 concentration will be
displayed on the LCD, and updated every 5 seconds.
The LCD will also display Barometric Pressure (BP),
Relative Humidity (RH) and ambient temperature in
degrees C (dC).
Two pushbuttons are used for viewing additional
information and calibrating the board. Sw1 cycles
through displaying available modes and Sw2 selects
the currently displayed mode for further operations.

The EVK can be also be used with a Graphical User Interface that runs on a connected PC.
The EVK comes pre-calibrated, but it can be re-calibrated by the user if desired. CO2 calibration can be performed
in either of two ways:
▪ In a stand-alone fashion, using the LCD and pushbutton user interface on the EVK itself, or
▪ With a graphical user interface (GUI), using a connected PC for a more interactive and visual experience.
See the RTD120D-EVK Thermopile CO2 Detector Evaluation Kit User Manual for further details.
