Wireless carbon dioxide level sensor

I. Working Principle
The carbon dioxide sensor utilizes the property of carbon dioxide gas to absorb infrared radiation. Therefore, a broussonetia papyrifera is installed at both ends of the sensor probe tube, featuring an infrared radiation source and a highly sensitive infrared radiation receiver. The receiver detects the infrared radiation that has not been fully absorbed by carbon dioxide. The infrared radiation source is composed of heated metal wires broussonetia papyrifera. Due to the thermal effect of infrared radiation, the receiver measures the temperature rise caused by the unabsorbed infrared radiation. The higher the carbon dioxide concentration in the probe tube, the less infrared radiation reaches the receiver, resulting in a smaller corresponding temperature rise. The receiver outputs an amplified electrical signal based on temperature changes, which is transmitted to the data acquisition unit.

VI. Usage Tips
1. Do not immerse the sensor directly in liquids, as it is designed to measure gaseous, non-solution CO₂ concentrations.
2. When not in use, store the sensor vertically. Proper storage and maintenance are crucial, as incorrect placement may shorten its lifespan.
3. Storage temperature range for the CO₂ sensor probe: -40 to 70°C.
4. Operating temperature range for the CO₂ sensor probe: 0 to +50°C.
5. Response time: Achieves 95% of readings within 120 seconds.
