Introduction

The next era of Smart Agriculture is being birthed with rapid developments in the Internet of Things (IoT). IoT technologies collect data from the field real-time to “close the supply demand gap, by ensuring high yields, profitability, and protection of the environment” (IoT Solutions World Congress). With continuously developing equipment, sensors, wireless connectivity, and software services, precision agriculture is on the rise amongst farmers and gardeners thanks to its ability to maintain all required environmental conditions of a plant in the optimal range. BI Intelligence surveys project that the adoption of IoT devices will grow 20% annually to triple the global smart agriculture market size by 2025, reaching $15.3 billion. It is the immediate solution to rising food and resource shortages and alleviates some hard work from the backs of aging farmers by ensuring stability and convenience.

Many smart farming devices are, not surprisingly, extremely expensive for its next-gen technology. However, there are plenty of easy, cost-effective ways to bring IoT farming/gardening into your very own living room. With this easy-to-follow tutorial, you can too :)

Let's get into it!!

(Note: In this project, I collaborated with San-arae farm (in Goseung, Korea), which is a shiitake mushroom farm.

All specific numbers involving light, temperature, humidity, etc. are tailored to optimal mushroom cultivation conditions. Please adjust as necessary!! :) )

Context

Smart farming is especially important for mushroom farming because mushrooms have very very specific requirements for growth.

SHIITAKE MUSHROOM FROM SAN-ARAE FARM

Temperature:

Shiitake mushrooms have an optimal growing environment of around 20~25oC. Most mushrooms thrive in temperatures around 70oF.

(Penn State University)

Humidity:

Because mushrooms have no skin, they lose moisture very easily. Consequently, mushrooms need a high-humidity environment. However, it is also possible to “drown” mushrooms as they breathe and exchange gases with the atmosphere. When growing mushrooms indoors the soil needs to be moist, not wet.

(Penn State University)

Light:

(https://www.rs-online.com/designspark/led-wavelength-vs-led-colour)

Mushrooms do not have chlorophyll and do not require light to survive. While the environment must be dark for mushrooms to spawn, they require light later on (1+ hour(s) a day) to form fruit bodies. Wild mushrooms survive in shady areas of woods where light is filtered before reaching the mushrooms. Mushrooms growing indoors can meet the requirement with indirect sunlight or lamps.

However, mushrooms can contain more vitamin D with exposure to UV light (specifically, 320 ~ 400 nm). A recent study found that shiitake mushrooms dried outdoors (with natural sunlight) for 6 hours over two consecutive days had more vitamin D than mushrooms that did not receive the same exposure. The mushrooms went up from 100 IU per 3.5 oz to nearly 46, 000 IU!! These mushrooms, tested a year later, showed to have preserved significant amounts of the vitamin.

Mushrooms grown indoors have no natural exposure to UV light, however, so a UV light/LED lights with the same wavelengths would go a long way!

Some may worry that excessive vitamin D in the mushrooms may lead to skin cancer, but experts note that it is impossible to overdo vitamin D amounts by eating mushrooms alone. Dr. Michael Holick, endocrinologist specializing in vitamin D at Boston University, says: “It’s perfectly fine.”

(Penn State University & Boston University)

So let's now move on to how this information was carried over to our software/hardware…..!!

Thermal management / Air conditioner

your typical AC

This project uses an automatic temperature control circuit to 1. Read the air temperature of the room with a temperature sensor (DHT11) 2. Use an infrared transmitter (like an AC remote control) to automatically change the temperature of the AC according to the room temperature. The air conditioner will react to the infrared signal commands to adjust the temperature (this is the same theory behind AC remotes!!). By periodically changing the set temperature, we can make the air conditioner work at a lower temperature for a long time and save electricity.

IR transmitter

This small component here is the IR transmitter!

Graphic OLED Display

Our friend here, the Graphic OLED Display, will display the current temperature, humidity and AC temperature in the format of:

“

Temperature: ___oC

Humidity:___%

AC Temp: ___oC

“

The code in this screenshot shows the array of infrared signal commands required for turning the AC on/off and for each temperature (in degrees Celsius). unsigned int Temp23[] represents 23oCelsius, unsigned int Temp24[] represents 24oC Celsius, and so on…

The infrared signal commands are different for different air conditioners/remotes, so make sure to ADJUST the numbers to suit your specific remote!!!!

code: desired temperature

This code shows the desired temperature of the room : as you may have guessed… 23oC. You should also change your desired temperature accordingly!

Light control

LED panel

Here, the LEDs are controlled by Arduino MKR1000 and the “LightController” library. This library is a light scheduler providing easy support for basic times of the day: moonlight, sunrise/sunset, etc. The software is constantly using the real time clock module (RTC DS3231, AT24C32) to check the time in the loop. Once the real time matches with the desired time (initialized in the code), it triggers the PWM pin to adjust the analog value. The LED intensity changes accordingly. In this specific project, the lights gradually turn on from 8:00am to 8:30am, stay at high intensity until 9:00am, and gradually turn off from 9:00am to 9:30am.

If you just want to turn the LEDs on and off manually, you don’t need this code – this code is specifically to automate the process to match a clock!

Assembling the circuit.. Hardware Configuration

HARDWARE CONFIGURATION

Pro-tip: include mushrooms in your daily diet!!!!

Vitamin D aside, fragrance aside, mushrooms are a nutrient bomb, containing a wide range of nutrients including B-vitamins, fiber, complex carbs, and important minerals such as selenium, copper, and potassium (Cooking Light). Low in calories and sodium and free of fat, cholestrol, and gluten, they’re the perfect diet. :)
