PRODUCT INFORMATIONTGS5141-P00 - for the detection of Carbon Monoxide
Features:

Applications:* Ultra compact* Battery operable* High repeatability/selectivity to CO* Linear relationship between CO gas
concentration and sensor output* Simple calibration* Long life
* UL recognized component* Meets UL2034, EN50291, and EN54-31
requirements* Residential and commercial CO detectors* Fire detection* Safety measures for lithium-ion batteries

Figaro’s TGS5141 is a battery operable electrochemical sensor which uses aunique electrolyte that eliminates the need for a water reservoir. By eliminating thewater reservoir used in TGS5042, the comparative size of TGS5141 is reduced tojust 10% of TGS5042. With its ultra compact size, this sensor is the ideal choice
for size oriented applications such as portable CO detectors, small residential COdetectors, and multi-sensor fire detectors. OEM customers will find individual sensors
data printed on each sensor in bar code form, enabling users to skip the costly gas
calibration process and allowing for individual sensor tracking.

The figure below represents typical sensitivity characteristics,
all data having been gathered at standard test conditions (seereverse side of this sheet). The Y-axis shows theoutput currentof the sensor (Iout/µA) in each gas. Output current is linear
to CO concentration, with a deviation of less than ±5% in therange of 0~1000ppm.

The figure below represents typical temperature dependency
characteristics. The Y-axis shows the sensor output ratio (I/Io)
as defined below. The linear relationship between I/Io and CO
concentration is constant regardless of the CO concentration
range.
I = Sensor output current in 400ppm of CO at various			temperatures
Io = Sensor output current in 400ppm at 20˚C/50%RH

PRODUCT INFORMATION

Basic Measuring Circuit:

C1The diagram at the right shows the basic measuring circuit ofTGS5141. The sensor generates a minute electric current which isconverted into sensor output voltage (Vout) by an op-amp/resistor(R1) combination.

R1

Figaro recommends the following electrical parts:
R1 : 1MΩC1 : 1µF
IC : AD708

NOTE: When voltage is applied to the sensor output terminal, thesensor may be damaged. Voltage applied to the sensor should bestrictly limited to less than ±10mV. An additional resistor or FET isrequired to prevent polarization of the sensor when Vc is off.
