CONTROL FARM SYSTEM USING ARDUINO AND GSM SIM800L

Control Farm System Using Arduino and GSM SIM800L - In some farming systems, temperature and humidity into one of the important factors in increasing agricultural productivity. Among the cultivation of strawberries, cabbage, mushroom, oyster mushrooms and others. These plants need certain conditions of temperature and humidity in order to grow well. But the conditions of climate / weather and more frequent fluctuations in temperature and humidity making becomes difficult to control. So it takes the appropriate technology solution that is able to manipulate the conditions of temperature and humidity of the air.

Control Farm System Using Arduino and GSM SIM800L

Of these problems, I designed a modern agricultural system is friendly user so easily applied and installed in agricultural systems. The device is named MCFAS (Multi Control Farm System) 6 in 1.The device is able to work automatically to control temperature and humidity in the six systems of cultivation/farming, namely: the cultivation of mustard plants, strawberry, mushroom, oyster mushroom, egg incubator and maintenance of poultry. The device is also equipped with protection and monitoring system for monitoring the condition of the system using SMS (Short Message Service) sent directly to farmers. 

MCFAS 6 in 1 is designed based microcontroller ATmega328P integrated with temperature and humidity sensors DHT-11 to detect the temperature and humidity, LCD 1602 to monitor and display the temperature and humidity conditions, RTC DS1307 to record time realtime and GSM Shield SIM800L to transmit information via SMS to farmers. ATmega328P microcontroller systems have been selected because they have a high reliability in process automation. 

By looking very promising market potential of strawberry plants, mushroom, oyster mushrooms and more, this device has great potential to be marketed. In addition, the system reliability and the relatively cheap price that I offer, making this device has great prospects for acceptance in the market.

This just opening it from me, about the problems in my country about farming system. If you are interested in MACFAS 6 in 1, please send comments below, I will try to explain the details of this system

HOW TO CALCULATE DISTANCE TO THE ULTRASONIC SENSOR (HC-SR04) ARDUINO MODULE

How to Calculate Distance to Ultrasonic Sensor (HC-SR04) Arduino Module -The ultrasonic sensors are electronic devices that can change the ability of the electrical energy into mechanical energy in the form of ultrasonic sound waves. The sensor consists of a transmitter circuit and a receiver circuit. This tool is used to measure the ultrasonic waves. Ultrasonic waves are mechanical waves that have characteristics of longitudinal and typically have a frequency above 20 kHz. Waves of Utrasonik can propagate through solids, liquids and gases. Ultrasonic is wave propagation wave energy and mechanical momentum that travels through these elements as interaction with molecules and the nature of the medium in its path enersia.

Example: Ultrasonic sensor (HC-SR04)

 HC-SR04 Ultrasonic Sensor detects objects by sending short pulses and then wait for the wave reflection (echo) .Sensor this form of ignition pulses (Trigger pulse) to interface to the device controller (microcontroller) so sending short 40kHz ultrasonic waves by the sensor will wait for instructions of controllers.

How to Calculate Distance to Ultrasonic Sensor (HC-SR04) Arduino Module

The calculation of the time required to receive a Ping sensor module reflection at a certain distance can be calculated using the following equation:

S = the distance between the sensor detected object.
TIN = the time between the transmitting and receiving the reflected waves.
V = the ultrasonic wave propagation speed in air at normal speed 344m / s.

There are 3 prnsip work of an ultrasonic sensor that is, the signal is transmitted through the ultrasonic wave transmitter. Signals emitted will propagate as sound waves at the speed of sound ranging from 344m / s. And the last signal was received will be processed to calculate the distance
