Overview
BV18 air-quality module adopts flat surface semiconductor gas sensor. The module has good sensitivity to volatile organic gases such as formaldehyde, benzene, carbon monoxide, ammonia, hydrogen, alcohol and smoke of cigarette, essence &etc. The module has been aging, debugged, adjusted and calibrated. So it has good consistency and high sensitivity.
Key Features
- High sensitivity
- Low power consumption, long life
- Calibrated before shipment
- 10 seconds to 3 minutes with auto-preheating function
- Faulty auto-check, High cost-effective
Applications
Air cleaner, intelligent integrated ceiling, air quality detector, ventilator, air conditioner, HVAC, fresh air system, smart building
