2) Sensors should be used under conditions where

the air exchange is greater than 200~300ml per minute in order to obtain the response speed as shown in the Specifications.

3) Life expectancy at 20˚C in normal air (1013hPa

 

/ 20.7% O2)is defined as the period until sensor output drops to 70% of its original value.

LUXMED Dual Beam NDIR Co2 Sensor

Ultra Low Power CO₂ Sensor For Laboratory Applications

 

 

 

Key Features

The LUXMED-Co2 is a CO₂ module for OEM applications that represents a breakthrough in low power gas detection making it ideal for battery powered, energy harvesting or wireless applications with tight energy budgets requiring long operating life. This Infrared LED based sensor offers a number of distinctive features over conventional CO₂ sensors.

Key features of the LUXMED-Co2 CO₂ sensor include:

Ο Continuous power consumption of 3.5 mW. With reasonable duty cycling (e.g. 15 min) battery life can be extended to 5+ years.

Ο Measurement ranges of 0-2%, 0-20%, 0-60%, 0-100% (custom range possible with volume order).

Ο  10 second warm up time.

Ο  Shock and vibration resistant.

Ο  Built in auto calibration feature.

Ο Options for on-board temperature and humidity measurement and extended temperature operating range of -13 to 131ºF (-25 to 55ºC).

Ο Simple, closed contact initiation of ambient or zero calibration.

Ο Runs cool, there is no heat generated that can interfere with temperature or humidity measurements

Ο  Flow through adaptor available.

The Breakthrough…

Conventional CO₂ sensors utilize a small incandescent bulb that generates a lot of heat and light energy in addition to the infrared energy used for the gas measurement. Instead of a light bulb, the LUXMED-Co2 uses a small light emitting diode (LED) that generates infrared energy only at the wavelength needed to measure CO₂. This is the reason for the dramatically reduced energy use of the LUXMED-Co2.

LED sensors have always been recognized as idea for low power gas detection but their development has been a great technical challenge. The LUXMED Co2 developed by a Scotland based company called Gas Sensing Solutions is the very first infrared LED product on the market that is stable enough and economical enough to be sold into measurement and control products.

The photo to the right shows the inside of the sensor with the LED emitter and photo detector at the top of the sensor. The yellow line shows the path of the infrared energy inside the sensor. The LED only emits infrared energy at the wavelength that is absorbed by CO₂. As a result any decrease in light getting to the detector relates to how much CO₂ is in

the air. Under normal operation the LED flashes 2 times per second but can be made to flash up to 20 times per second.
