Warm-up Time: Less than 7 seconds
Sensors: NDIR CO2 sensor, temperature and humidity sensors
Signal Output: Supports data export/data logging via RS485/relay

Usage:
The air quality meter allows for accurate and reliable measurement of CO2 levels, temperature, and humidity, making it ideal for use in offices, homes, warehouses, or industrial spaces. It can also be used as an IoT controller, enabling the integration of data into larger system networks, with RS485 and relay outputs allowing for data transfer to other devices.

Advantages:

Real-time display: See CO2, temperature, and humidity levels in real-time, allowing for quick response to changes in air quality.
Ease of use: Simple interface and light indicators make it easy to understand the environment being measured.
Wide measurement range: Suitable for both home and commercial/industrial spaces where maintaining the correct CO2 concentration and air quality is important.
Advanced sensors: NDIR technology ensures precise CO2 measurement.
IoT compatibility: RS485 output support allows integration into larger automation systems.
Quick warm-up: Operates in less than 7 seconds after being powered on.
Disadvantages:

Requires external power supply: The DC12V adapter may require additional equipment if there is no access to the correct outlet.
Limited humidity measurement accuracy: While the accuracy is ±5% RH, this may not be sufficient in certain situations, such as in very dry or humid regions.
Large size: With a width and height of 86 mm, it may be slightly large for spaces with limited room.
