DIGITAL MOISTURE MONITORING SYSTEM EMBEDDED IN PIC

Abstract

Digitalization in agriculture can eliminate many malicious effects in the agricultural industry and reduce uncertainty due to the uncertainty in weather and complex agriculture system. This study designs a PIC based web-service oriented architecture to achieve achieves more flexibility, affordability as well as usability through adapting the Web services and PIC based Sensor integrated with GSM/GPRS based mobile application model to take progressive data of temperature, level of soil moisture, photo taken from the harvest field and renders these data into a web server to produce report for farmers or agriculture experts through android devices. These data are then stored in the web server as per date and time. Besides, the ratio of soil moisture in a specific area is calculated and displayed in a graph in the web page. Moreover, an android application “Smart Agriculture BD” has been constructed to incorporate the field images along with other data in the web server. In order to collect the data for the humidity of soil grove-moisture sensor, a temperature sensor for calculating temperature, android app for retrieving collected images and SIM900A kit (GSM/GPRS module) has been integrated with PIC Microcontroller 16f877A to forward the data to a web server for immediate use. Henceforth, a user can predict the field condition by manipulating the data and take the imperative decision to overcome any detrimental effect on crops due to nature.

Existing System

Wireless sensor network, Sensors used

Proposed System

The proposed system entirely involves incorporation of different sensors, GSM/GPRS module with PIC microcontroller, rendering data through web and storage in a web server by displaying the required information. The usage of android application is also integrated within the system. At first, all the hardware and equipment like groov-soil moisture sensor, temperature measuring sensor, GSM/GPRS wireless device and the PIC kit (holding the microcontroller PIC 16f877a) are being set to the field area. The moisture sensor is deployed in the soil to measure water adjustments around it. Temperature sensor and SIM900A (GSM module) are also integrated with the PIC board set on the experimenting field. After the proper deployment of mentioned hardware and equipment, the devices start to acquire data and store those in EPROM placed on the board of PIC microcontroller. Besides, the GSM module starts forwarding these collected data through the GPRS system; temporarily storing in EPROM, which are likely to be moved to the network for further online storage. Moreover, the android application takes photos of the field and then uploads the images to the server. All the obtained and simulate data are then stored in the web server as backup. Finally, the earned data along with the pictures are viewed and accessed by a user through a web page.
