1、DESCRIPTION
The MAQ01-AV-P1 carbon dioxide sensor is a cost-effective, maintenance free, and easy to install infrared carbon dioxide sensor that can be applied to indoor ventilation monitoring. By detecting the carbon dioxide gas content in the surrounding environment online, and outputting the measurement data in analog form for the monitoring platform to collect. It can help intelligent buildings save energy, reduce operating costs, and improve indoor air quality.
This product is widely used in air quality detectors, air purification equipment, fresh air systems, air conditioning control, smart homes, IoT environmental information collection, agricultural production, cold chain transportation and other related fields.

6、note
From a condensation state to a non condensation state, the system can return to normal operation within 2 hours.
Please avoid vibration as much as possible. If subjected to vibration, dropping, or prolonged welding, it may result in a decrease in the measurement accuracy of the sensor. If severe vibration or drop occurs, the accuracy of the product needs to be verified.
Do not use for a long time in environments with high dust density.
Avoid long-term use in acidic, alkaline, and strongly oxidizing gas environments containing HF, H2S, SO2, HCL, NOX, NH3, PH3, CL2, F2, O3, H2O2, etc。
Avoid applying external forces in any direction to the casing, as it may affect sensor performance and potentially cause damage
7、quality assurance
Within 12 months of the product leaving the factory, free repair services will be provided based on normal use and non-human damage.
