📋 目次
1What CO2 measurement range should I look for in an air quality sensor?
Look for sensors that measure CO2 levels between 0–2000 ppm for indoor use, as this range covers typical office and home environments. Higher ranges may be useful for industrial or ventilation system monitoring, but most residential models cap at 1000–2000 ppm for accuracy and cost efficiency.
2How accurate should a CO2 sensor be for home or office use?
For general use, a sensor with ±50 ppm accuracy is sufficient, though higher-end models offer ±10–20 ppm for more precise monitoring. Accuracy matters most in environments where ventilation is critical, like classrooms or offices with many occupants.
3What’s the difference between NDIR and electrochemical CO2 sensors?
NDIR (non-dispersive infrared) sensors are more accurate and durable for long-term use, making them ideal for indoor air quality monitoring. Electrochemical sensors are cheaper but degrade faster and are better suited for short-term or outdoor applications with lower accuracy requirements.
4How often should a CO2 sensor recalibrate, and why does it matter?
Most CO2 sensors require recalibration every 6–12 months to maintain accuracy, as sensor drift can occur over time. Regular calibration ensures reliable readings, especially in environments where air quality directly impacts health or productivity.
5Are wireless or smart CO2 sensors worth the extra cost?
Wireless or smart sensors with Wi-Fi or Bluetooth connectivity are worth considering if you need real-time data on a phone app or integration with smart home systems. They offer convenience and remote monitoring, though wired models are often more reliable and cost-effective for basic use.
