The use of internet of things (IoT) technology in vertical farming has the potential to greatly benefit the industry by providing a more efficient and sustainable way to grow plants. IoT-based systems in vertical farming can monitor and control various environmental factors, such as temperature, humidity, and light levels, to optimise growing conditions and increase productivity. These systems can also automate certain aspects of the growing process, such as irrigation and nutrient delivery, saving time and labour costs. Additionally, IoT technology in vertical farming can provide real-time data and analytics, allowing growers to make data-driven decisions and improve the overall efficiency of their operations. This paper presents a working prototype of a sensor system for vertical farming that could easily be integrated with any vertical farming system. The sensor design was based on a thorough study of existing vertical farming systems, considering factors such as cost, power consumption, and suitability for indoor use. The sensors store and display system parameters and send data to a cloud-based server for remote access. The functionality has been confirmed through testing and evaluation of individual components.
