-  * Always buy the PMS7003 sensor with the adapter cable included. 
-  * There are two versions of the MH-Z19 sensor, preferably choose the MH-Z19B version.

-The Air Quality Monitor should be installed in a well-ventilated area outside the house, not exposed directly to elements such as rain, or direct sunlight. \\ A porch or a balcony is a good place to install it. \\ Choose an enclosure suitable for the environmental conditions where the AQM will be installed. If exposed to rain, the enclosure should be waterproof but allow air circulation.
