Design of Indoor Environment Monitoring System Based on WiFi

At present, the people are concerned about the indoor environmental problems. The indoor environment monitoring system is designed. The paper designed and developed temperature and humidity acquisition module combining DHT11 and Arduino, and developed wireless transceiver module based ESP8266 to achieve a temperature and humidity information. The system requirements, system design, correlative hardware circuits, control flow chart and software design are depicted in details. This system can realize data acquisition, processing, transmission, and control temperature and humidity information in the client of the phone. The system functions verification and performance test results show that this system meet the needs of most users, has a good practical significance.
