CO2 Sensor

Introduction

♦  CO₂ Sensor is infrared gas absorption and testing sensor. It has good selectivity, high sensitivity, oxygen free dependent, long service life, low power consumption and no preheating requirement.

Usage

♦  CO₂ Sensor can be used to detect concentration of CO₂. There are ventilation opening on the electrode wall.

♦  Connect sensor to datalogger and computer. Place the electrode into the air to be measured.

Notes

♦  Calibrate the sensor periodically which should not be greater than 3 month.

♦  Impact due to temperature and humidity to the sensor is very small. It can be used properly under condition where relative humidity is 95%.

♦  Try not to impact testing result by exhaled CO₂.

♦  If liquid flows into the electrode, it will destroy the sensor completely. Try not to use the sensor under condition which is full of dust.

♦  CO₂ is heavier than air so that it will sink to bottom of bottle. Use container as small as possible when doing experiment because it will be easier to collect CO₂.

♦  Reserve the electrode in a place without CO₂ due to the working principle of electrode. When it is placed inside room, it can be stored by 2 years.

♦  The CO₂ Sensor is an infrared gas absorption detector named infrared CO₂ Sensor. It has good selectivity, high sensitivity, no oxygen dependence, long life, low power consumption without preheating by comparing with the chemical sensor.

Typical experiment

♦  Compare gas exhaled by human with the environmental gas

Others

♦  Plant's photosynthesis

♦  Explore breathing regulation of saccharomycetes

♦  Assessment of air quality

♦  Generation velocity of CO₂ gas in chemical reaction
