Abstract: Agriculture in most countries is largely dependent on the environmental conditions and climate. Real-time remote monitoring of field conditions allows for early detection of unfavorable conditions developing in the field that is generally a laborious task taken up by the farmers themselves. Additionally, with the rapid shift in climatic conditions and issues pertaining to global warming, the rainfall dependent agricultural yield is promptly affected. In this paper, we present a wireless system using nRF24L01 RF modules to monitor the farm environment conditions and operate the final control element aimed at implementing drip irrigation. The proposed system is designed to be economical and having a capacity for further expansion, allowing the widespread devices across the farm to be controlled. The soil sogginess level is measured by a self-made soil moisture sensor. A ball valve is actuated based on the levels of soil moisture, temperature and humidity checked against a set of predefined levels. The collected data is then pushed onto a cloud platform for future study or use. Keywords: Wireless sensor network, real-time monitoring, nRF24L01 RF module, highly economical and efficient system

Saat ini para petani sayuran dalam menanam jenis sayuran masih menggunakan cara tradisional dan belum memperhatikan kondisi tanah yang sesuai untuk jenis sayuran yang akan mereka tanam, hal ini menyebabkan pertumbuhan sayuran menjadi kurang maksimal. Oleh karena itu diperlukan sebuah sistem yang mampu memberikan informasi kadar tanah dan memberikan rekomendasi jenis sayuran yang cocok untuk ditanami. Sistem yang akan dibangun berbasis mikrokontorler arduino, sensor soil moisture, sensor pH, dan modul ESP8266 yang digunakan untuk mengirimkan data hasil dari pembacaan sensor ke perangkat mobile secara real-time  untuk diproses dan menghasilkan rekomendasi jenis sayuran yang cocok berdasarkan data hasil dari pembacaan sensor. Berdasarkan hasil pengujian, sistem ini telah mampu menampilkan kondisi kelembaban tanah, kadar pH dengan baik dan mampu merekomendasi jenis sayuran sesuai dengan kondisi hasil pembacaan sensor, sehingga harapannya dapat membantu para petani sayuran dalam menentukan jenis sayuran yang akan mereka tanam dan mampu meminimalisir resiko gagal panen. Kata Kunci: Arduino, soil moisture, pH, mobile web

The quantity and quality of water present in the soil determine to a greater extent the performance of agricultural crops. Real-time determination of moisture content has a greater advantage over the traditional gravimetric method of determining soil moisture content. Thus, this work was based on the design and construction of a cost effective digital capacitive soil moisture sensor for real-time measurement. The moisture sensors comprised four integrated units namely: power supply unit with a 9V DC battery as a power source, sensor unit with a locally sourced Printed Circuit Board (PCB) as the single sensing probe, control unit made up of PIC16f877 microcontroller programmed with a C language and the C source code compiled in Corporate Computer Services Compiler (CSS C) compiler development environment, and a 16x2 display unit which displays the readings in percentage moisture content (%MC) and capacitance (μF) of the soil obtained from the sensor on its screen. Standard gravimetric moisture content was carried out to get the calibration factor which was used to calibrate the sensor for reliability. The validation was done by taking the reprogrammed (calibrated) sensor to the field for further measurement, after which soil samples were collected for further gravimetric analysis. A regression equation was obtained by plotting the moisture content obtained from gravimetric method (%MCG) against that from sensor reading (%MCS) with a high degree correlation coefficient (R2) of 0.998. The developed capacitive soil moisture sensor is cheap, portable, reliable and easy to use even by local farmers.

Soil moisture sensor is an instrument for quick measurements of soil moisture content in the crop root zone on real time basis. The main objective of this research was development and evaluation of an indigenous sensor for precise irrigation scheduling. The various parts of sensor developed were ceramic cup, acrylic pipe, level sensor, tee, reducer, gland, cork, and end cap. The designed system was successfully tested on okra crop and calibrated with frequency domain reflectometry (FDR) by three methods of irrigation, i.e. check basin, furrow and drip, respectively. The average depth of water depletion in modified tensiometer by these methods was 27 to 35 cm at 50% management allowable depletion (MAD) of field capacity. This depth was useful for the level sensor to be installed inside modified tensiometer for real time irrigation scheduling. The correlation coefficient (R2) between soil moisture content obtained from the developed sensor and FDR was 0.963. Sensor network was integrated with global system for mobile communication (GSM), short message service (SMS) and drip head work to develop an automated irrigation system. This would enable farmers to effectively monitor and control water application in the field by sending command through SMS and receiving pumping status through the mobile phone.

The developed system consists of a solenoid valve and water pump which are directly linked to a microcontroller (ATMEGA-328PU) unit through a transistor -network based relay switching unit. A soil moisture sensor linked to the soil senses the dryness and wetness of the soil. The microcontroller and soil moisture sensor utilizes a 5V power supply unit given through a regulated supply via a regulator called LM7805.A 12V power supply units activates the normally open units of the relay linked to the solenoid valve and the pump. Whenever the dryness of the soil is sensed, the microcontroller decodes and sends an instruction to the solenoid valve to open and the water pump to start driving the water which is sprinkled through the sprinkler. The performance of the system has been evaluated and the response time is fast.

Currently, the control of cultivated plants is still manual, where farmers watering and checking soil moisture on the planting object. However, we cannot avoid technological progress in this life because technological progress will run following scientific advances. Therefore, every innovation is created to provide positive benefits for life. The ideal chili cultivation planning requires information about climatic conditions that play a significant role in chili cultivation is rainfall. Plant growth will be incredible if there is sufficient water supply; humidity for chili plants ranges from 60-80%. Therefore, chili cultivation planning must pay attention to rainfall because related to water availability. Smart Garden prototype design is a solution for taking appropriate actions during extreme weather and reducing human error.

The proper usage of water is essential in irrigation because of the shortage of water. The shortage of water is due to lack of rain and continuous supply of water for irrigation as a result lot of water got wasted. It is very much essential to manage the use of water efficiently. The main objective in this project is to watering crops automatically by monitoring soil moisture for supply water based on the requirement and to maintain the water level in the overhead tank. This system suits for all climatic conditions. This project proposed on the usage of automatic irrigation system based on Arduino board, soil moisture sensor, float switch and solar panel. This automatic irrigation system senses the moisture content of the soil and automatically switches the solenoid valve and the overhead water level is monitor by float switch sensor and the power the required for the entire system is generated by using the solar panel. It will automatically control the water level in the tank also. The Global system for mobile communication (GSM) module sends the message, whenever the valve is turn ON and OFF. This project is fully automatic to support farmers, provides water as required, deploys renewable energy, minimize man power, less space, low cost and user friendly.
