A way to detect and adjust indoor air quality by wireless is proposed based on field programmable gate array（ FPGA）

and data collection

Bluetooth communication

drive and control principle for stepping motor are analyzed. Experimental results show that the system realizes functions of information collection of temperature indoor

display on LCD

communication and remote adjustment and processing by upper PC. It assures detect real time and reliability of indoor air quality detecting data. The system can be used in place which air quality is hoped to be evaluated

such as green smart home

vegetable planting greenhouse and so on.
