Design of monitoring system based on android platform and GPRS

This paper presents a wireless remote monitoring system of water quality parameters based on Android platform and GPRS communication technology. This system realizes the remote collection, storage and management of water quality parameters, and also realize the remote control of the control nodes. In acquisition part, sensors collect data which is sent to the remote server through GPRS module, and water quality parameters from the server is sent to the Android mobile phone. In the control part, the control commands from the android mobile phone is sent to the server, and the server again send it to the lower machine to control the control nodes. After practical testing to the system in Liyang, Jiangsu province, temperature measurement accuracy reaches 0.5 °C, PH measurement accuracy reaches 0.3, water level control precision can be controlled within ± 3cm, dissolved oxygen control precision can be controlled within ±0.3 mg/L, all the indexes can meet the requirements.
