Abstract

In order to promote the development of intelligent agriculture in our country, this paper puts forward a wireless remote monitoring system of water quality parameters which is based on Android mobile phone platform and GPRS communication technology, the system realizes the remote collection, storage and management of water quality parameters such as the water level, temperature, PH and dissolved oxygen, and also realize the remote control of the control nodes. The 16-bit microprocessor MSP430f149 of TI company is adopted in acquisition part, and also 12 high-precision AD converter is used, the sensor collected data through the GPRS module which is sent to the remote server, and water quality parameters from the servers is sent to the Android mobile phone. The PID control is adopted in the control part, the control commands from the android mobile phone is sent to the server, the server again send it to the lower machine to control the water level regulating valve and increasing oxygen pump. So the Android mobile phone system can complete the monitoring of water quality parameters. After practical testing to the system in Liyang, Jiangsu province, all the indexes can meet the requirements, this system is very suitable for aquaculture.
