CDM4160 is a new unit which uses TGS4160, Figaro's durable solid electrolyte CO2 sensor. Due to 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 CO2 concentration can be obtained.
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.
Features:
* High selectivity to CO2
* Long life
* Maintenance free
* Pre-calibrated
* Low cost
* Wide detection range
* Excellent durability
Applications:
* Indoor air quality control in offices, homes, and factories
* CO2 monitors

1.General description
The luminox family (lox) is a range of factory calibrated oxygen sensors which measure ambient oxygen partial pressure (ppo2) levels using the principle of fluorescence quenching by oxygen.
By default luminox measures ppo2 (mbar) and temperature (°c). An optional pressure sensor enables luminox to also measure barometric pressure (mbar) and to convert the ppo2 reading to an oxygen concentration (o2%).
The sensor benefits from low power operation, traditionally associated with electrochemical sensors, while providing a much longer lifetime due to the non-depleting sensing principle.
Luminox is ppo2 and temperature compensated, enabling accurate operation over a wide environmental range without the need for additional system components. Unlike other sensor technologies, luminox is very stable and robust, does not contain lead or any other
Hazardous materials and has negligible cross sensitivity to other gases.
2.Cleaning
The housing of the sensor can be cleaned using a damp cloth. The sensor should not be immersed in any cleaning media.
Full application and technical support can be provided by our knowledgable and highly experienced engineering team if required.

Description
The ngm2611 is a pre-calibrated module for natural gas alarms which is precisely
Calibrated in figaro's humidity and temperature controlled facility.
The most important process in manufacturing reliable resdential gas alarms is
Adjusting the alarm point. Calibration is a complicated and time consuming
Process which also requires a substantial investment in calibration equipment. By
Eliminating the costly calibration process, this module enables users to easily and
Simply manufacture residential natural gas alarms. Figaro has taken the complexity
Out of designing a gas detector circuit by providing users with a temperature
Compensation circuit which combines a built-in thermistor and individually adjusted
Load resistor together with figaro’s low power methane gas sensor.
A connector allows easy replacement of the module for the purpose of periodic
Sensor renewal. This input/output connector enables easy installation of the
Module into the gas detectors’ mother board. This same mother board can be
Used for both methane and lpg gas detectors by simply changing the module.
This module is designed to meet the performance requirements of en50194, and ul1484.
Please refer to “technical information for tgs2611” for sensor sensitivity characteristics.
Refer to “application notes for tgs2611” for further information regarding circuit design.
