FAQs - AQI Sensor
What does an AQI do?
Understand indoor air pollution: indoor air quality monitor can measure indoor PM2.5, PM10, carbon dioxide, temperature and humidity, and other elements, reminding people to pay attention to whether the indoor environment is healthy and suitable for living.
Monitoring air quality pollutants: Indoor air quality monitors can monitor these toxic and harmful gases: formaldehyde, ammonia, carbon monoxide, sulfur dioxide, nitrogen dioxide, TVOC, and other pollutants.
Establish an air quality big data management platform: indoor air quality monitor, which used to be just a simple instrument, now it can establish a real indoor air quality management system through the Internet of Things. Air quality data does not need to be manually collected and is automatically collected and transmitted to the online environmental management cloud platform. Users can directly understand environmental data through mobile phones and PC.
What precautions should be taken when measuring?
This product monitors toxic gas concentrations down to approximately 2 ppm, making it suitable for use in confined spaces where toxic and hazardous gases may be generated, ensuring safety in production environments. However, in open air, gases diffuse rapidly, resulting in very low toxic gas concentrations. Detecting toxic gas concentrations in such environments requires a sensor with ppb-level accuracy.
If our AQI sensor is used to measure gas concentrations in open air, the reading may remain at zero for extended periods because the gas concentration is too low to reach the minimum detection limit.
What are the dimensions of this air quality index sensor?
The overall device dimensions are: 168mm (diameter) x 52mm (thickness).
What is the material of this AQI sensor?
High-strength industrial ABS housing.
This air quality index sensor consists of two parts: a mounting base and a sensor body. The housing features a porous structure that ensures natural air circulation, effectively dissipating heat from the internal circuitry and ensuring more accurate gas sensor measurements.
How do I install the AQI sensor?
Our AQI sensor consists of a mounting base and a sensor unit. After determining the installation location, secure the mounting base to the wall or ceiling with screws, then snap the sensor into the mounting base using snaps.
What is the warranty period of the Renke AQI sensor?
The warranty period of the monitor is 1 year. The warranty only applies to manufacturing defects.
How to read air quality index sensor?
After the air quality index sensor is installed, it will automatically detect various elements of the current environment, and upload the detection results to the free cloud platform or -K platform through RS485 or wifi signals, and users can log in to view the data freely.
Where to use the air quality index sensor?
AQI sensors are widely used in building HVAC, building energy-saving, smart homes, schools, hospitals, airport stations, and other places.
How indoor AQI sensor work?
The AQI meter detects various elements through built-in multiple sensor modules.
