Abstract

The present project aimed to develop and calibrate a low-cost chlorophyll meter and purchase the data acquired with the data found with the GreenSeeker® sensor on predetermined surfaces. The apparatus was developed using materials from the local market and recycled. The readings were taken at 11:00 am on asphalt surfaces, healthy vegetation, dry vegetation, mixture of dry and healthy vegetation and gravel, all at a distance of 60 cm. The collected data were compared using Excel and a graph with a trend line was created to evaluate the correlation between the two devices. The correlation factor was satisfactory, reaching an R² greater than 0.90. The cost of building the apparatus was below GreenSeeker® values.
