Story

Overview:

Singapore, with it’s constant efforts and high hopes, hopes to achieve the “30 by 30” target, which is to push the agri-food food industry to produce 30% of our nutritional needs locally and sustainably by 2030. This target is featured in the Singapore Green Plan 2023. However, Singapore, having land scarcity which is dedicated for agricultural purposes, relies heavily on import, which will not be the most ideal option in the future as the world population is growing. The global demand for food is projected to be 60% and higher higher by 2050. With Singapore having less farms there is also a labour shortage of farmers.

Driving Question:

How do we compensate for lack of farmers by making it more efficient to keep crops healthy with a consistent irrigation system, monitoring its environment and have a pest control system?

Our Project:

Our Smart Farming System uses a Env II to monitor the humidity, pressure and temperature to monitor the crops environment. With a QR code that is displayed on the M5Stack a wireless connection can be made and the user will be able to see the readings for humidity, pressure, temperature and soil moisture so that the the user may gather data to grow crops more efficiently.

A watering unit that acts as a soil measuring unit that can determine if the soil is dry by measuring its moisture and act as a pump to water the crops, it is set to turn the pump on, if the soil moisture is >1550.To avoid under- or over watering their crops, farmers can carefully monitor the weather forecast, as well as soil and plant moisture, to adapt their irrigation schedule to the current conditions.

A light unit will determine if there is too much light which is a value of >700 and will shelter the crops by turning the servomotor which the shelter is placed on.

Lastly for deterring pest a PIR will detect any motion, if activated, the M5Stack will emit a sound with a volume of 0.1, a beep frequency of 1800 with a duration of 200ms to scare the pest trying to get to the crops. This compensates for the lack of farmers lessening the load for farmers.

Displays on M5Stack:

The humidity icon:

The pressure icon:

The Soil Moisture Icon:

If Env II detects the temperature is > 30 :

Hot image

Else if temperature is < 25:

Cold image

Else:

Balance image

If light unit detects a value of > 700:

Hot sun Image

Else:

If the PIR Unit detects motion it will show a label of Pest Detected! and display this image:

Else it will show a label of Crops are safe! and display this image:
