Smart Farming – Bluetooth Low Energy Sensor

Smart Farming – Bluetooth Low Energy Sensor

Smart Faming .


In the developed world farmers are beginning to utilize the ideas behind the Internet of Things to increase their productivity. Labeled ‘smart farming’, these systems usually utilize satellite remote sensing for analyzing big fields. Other options include monitoring points of interest with specialized sensors that connect to a personal network. Both options require big infrastructure investments and are therefore only viable for big farms. But especially in developing countries, climate change is threatening food security. Smart farming can help to increase resilience to extreme weather and increase production. Most farmers in developing countries are working in small fields and are unable to utilize the current smart farming technologies.

To enable these farmers to benefit from smart farming techniques other sensors are needed. The idea of this thesis is to create a prototype of a soil monitoring sensor that can communicate via Bluetooth Low Energy (BLE).
