Aiming at the problems of high cost

complex wiring and poor portability of monitoring terminal of present agricultural environment monitoring system and multi-user remote monitoring requirements

a kind of system is designed based on mobile phone as monitoring terminal and its App monitoring data can be shared remotely across devices. The system uses SHT11 sensor to collect environmental temperature and humidity data

through micro-control unit（ MCU）

dew point data is calculated. Local Android mobile phone can receive data via Bluetooth module and save data to Tiny Web DB via mobile Internet

multiple remote Android phone can share monitoring data from the Tiny Web DB

and can realize voice

vibration and text alarm. The system has the advantages of low cost

good portability of monitoring terminal and strong function expansibility. The test results show that the system runs with high stability

precision and has wide application prospect.
