Abstract
GrowFruit is an Internet of Things-based low-cost real-time radial growth-rate measurement device for fruit or stem. The working principle is measuring the growth of multiple crops up to 128 different inputs utilizing a single Texas Instrument-based 32-bit ultra-low-power microcontroller. The system utilizes Flex sensors, each of 4.5 in. to measure the change of circumference of the crop. The bending angle of the Flex sensor generates voltage, and via ADC, is fed to the microcontroller in the form of a digital signal. With the help of the Quectel M95 GSM modem, the microcontroller sends the signal to the cloud for storage and analysis of the growth rate data. As the system measures the perimeter changes of fruits or stems, more precise growth information is obtained.
