1. An environment monitoring system for precise agriculture based on
wireless sensor networks
Abstract
Precision agriculture is a new development in traditional agriculture. In precision
agriculture, production environment is monitored, and the monitored data is used to derive the
most suitable environment management decision which employs control and adjustment
solutions to obtain better product yield. In this paper agriculture parameter monitoring is
processed by uploading the data’s to the internet using GPRS technology.
Existing System:
The existing system includes wireless technology of short distance and the agricultural
data’s are transmitted and viewed in home PC. There is no way of monitoring the data through
internet from remote place. Hence we go for new system.
Proposed System:
In this system the agricultural land or greenhouse parameters like temperature, humidity
and water-level is going to be monitored and uploaded in internet using GPRS technology. In
this the sensors are interfaced with the Microcontroller. A threshold value will be set for each
sensor in the microcontroller, and if the sensor value goes beyond the threshold value the
controller will switch ON the Pump Motor to reduce the parameter abnormalities. And the sensor
values will be continuously updated in internet via GSM/GPRS Modem.
