A microcontroller based instrumentation package was designed, developed and mounted on an 81 kW Massey Ferguson 399 (MF-399) tractor. This package continuously measures and monitors various performance parameters of the tractor and implement. These parameters were: actual forward speed, theoretical forward speed, slip, fuel consumption and implement draft. The package comprised of four components: power supply, transducers, data acquisition, and display unit. Power was taken from the tractor battery. The data acquisition system was capable of scanning the data at 0.1 s intervals. The system performed well during the field operations and the results obtained showed that the accuracies of the transducers were acceptable. |

ABSTRACT: The aim of this study was evaluate the longitudinal distribution of maize seeds using a seeding line prototype, whit a microcontroller data acquisition system, at different speeds and types of horizontal feeder discs. Initially it was constructed a prototype simulator of seeding line, in the laboratory, and mounted two systems of microcontroller data acquisitions with infrared sensors for maize seeds counting. A test was conducted in a completely randomized design in split plots with factorial scheme of treatments 5 x 2 x 2, being the parcel two types of microcontroller data acquisition systems (infrared sensors in parallel and an diffuse infrared sensor), the factors were two feeder discs of maize seeds (inclined and normal) and five sowing... |
