provides an easy way to evaluate the RTD120D dual-
channel thermopile in a CO
It operates stand-alone or with a PC running CO
Detector Evaluation Software, making the CO
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:

Introduction
The Thermopile CO Detector Evaluation Kit is
2
designed for evaluation of the Renesas' RTD120D
dual thermopile in a CO
such as to detect the ambient CO
has a NDIR (Non-Dispersive Infrared) thermopile-
based gas sensing circuit and the concentration of
CO gas is measured based on the intensity of the
2
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

Getting Started
2
Right out of the box, the EVK can begin measuring
CO levels right away:
2
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 CO
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.
