Product Details
Automotive Carbon Dioxide Sensor KGD - ACDS - 306 for Detecting In
- vehicle CO₂ Concentration
Product Introduction
The automotive carbon dioxide sensor KGD - ACDS - 306 works in
intelligent coordination with automotive air - conditioners,
striking a good balance between driving comfort and economy. This
advantage is particularly important in new energy vehicles.
Meanwhile, when applied in cars, the carbon dioxide sensor can
determine whether there are any remaining lives inside the vehicle
based on the changes in the concentration of CO₂ gas after locking
the car, and give an alarm in a timely manner.
Product Features
- Dual - light - source NDIR technology
- Ensures measurement accuracy across the full temperature and
pressure range
- The detection range can reach 40000ppm, used to detect the leakage
of R744, a new - type automotive air - conditioner refrigerant, and
give an alarm in a timely manner
- Can be deeply integrated with PM2.5 sensors
- Small zero - point drift and good stability
