TECHNICAL INFORMATION FOR CDM4160
Technical Information for the CDM4160 CO
CDM4160 is a new unit which uses
TGS4160, Figaro's durable solid
electrolyte CO
sensor. Due to
2
Figaro's proprietary idea for signal
processing with a microcomputer,
no maintenance is required for
this module. By application of DC
voltage to the module, an analog
output voltage proportional to
CO
concentration can be obtained.
2
The module can generate a control
signal based on a user-selectable
threshold concentration. The
Features mentioned above make this
module ideal for air quality control
Applications in homes, offices and
factories as well as in the field of
agriculture.
