What would happen if we can institute IoT into the greenhouse?

The ideal condition for cultivating crop includes temperature, humidity, amount of light, concentration of oxygen and carbon dioxide in the greenhouse; and administration of these conditions has always resulted in large labor. But in the era of IoT, greenhouses using IoT technology is becoming the next trend.

IoT technology in greenhouses can monitor the condition of the greenhouse in real time using various sensor measurement technologies and network communication technologies, informing the cultivator via mobile or alarm service when a symptom is discovered by setting the ideal temperature of the crop. The cultivator can remotely control requirements for greenhouse management such as the temperature inside greenhouse, lighting control, intruder detection, and water supply. As result, the size of the greenhouse can be significantly expanded. Furthermore, linking the cloud system would also enable ‘machine learning’ system using the accumulated big data.

Another increasing trend these days is farming in metropolitan areas. People living in large cities can grow a vegetable garden in a small vacant lot to cultivate crops and harvest.  Most of these case are as hobbies, and IoT is applied, people can remotely control their farm while they are doing other activities.

Howeve the con is that it is expensive.

Therefore, I would like to introduce a cost effective approach.

The following are projects using Arduino with low cost.

1. The Greenhouse is Operational


This project shows how to control temperature inside the greenhouse using Arduion and Ethernet Shield. The author used fan and heat light to control and set desired temperature to Arduino. When the inside temperature of greenhouse is high, he lowered the inside temperature by operating the fan to enter the outside air, and when the inside temperature of greenhouse is low, he increased the temperature by operating Heat Light. Arduino sends data such as the inside temperature, the outside temperature, brightness of the sun, fan speed, and brightness of heat light, to a separate server via Ethernet Shield. And the received data can be analyzed as a graph.

2. Arduino Greenhouse


This project shows how to monitor inside/outside humidity, temperature, soil moisture, and light using Arduino.

Arduino Mega operates small humidifier to maintain preset humidity, temperature, and soil moisture or controls them by entering outside air using fan. Users can check the value of sensors and operational status of fan using the data described on TFT LCD.

Arduino UNO receives value of sensors from Arduino MEGA and then sends them to instance of Mysql operated in Amazons web service.

3. Arduino ile Sera Projesi


This project is written in Turkish. The title in English is “Greenhouse project with Arduino”.

This project shows how to display the measurement of temperature, humidity, and soil moisture via web server. It enables environment for plants to grow by controlling the fan, heating system, steam system, and pump.

The above projects are all made by individual makers to cultivate crops. After reading them, users can try to make their own cost effective Smart Greenhouse.

I’d like to recommend try to create your own smart greenhouse and eat homemade crops!
