Tips: How to choose the right air quality sensor for home use?

When choosing an air quality sensor for home use, it is recommended to focus on the following points: First, make sure that the air particulate sensor is capable of detecting the type of pollutant you are concerned about. Second, check the sensor's detection accuracy and response speed. In addition, consider whether the air quality monitoring sensor has real-time monitoring, historical data logging, and compatibility with smart home systems. Finally, choose the right sensor according to the size of your home and make sure its coverage is adequate.

Indoor air quality sensors require regular maintenance to ensure their accuracy and long-term stability. Typically, the detection element of an air quality transmitter needs to be replaced every 6 months or 1 year. Some sensors offer automatic calibration, but it is also important to regularly check the working condition of the device and clean the sensor surface to avoid dust accumulation.
