Abstract

An OPTO-ELECTRONIC SENSOR system was designed, developed and evaluated. The performance of this sensor was laboratory investigated for SEED spacing uniformity through a measurement of time intervals between SEEDs as well as front-to-back location of SEED drop events relative to the planter. The device consists of a rectangular photo gate block with 24 phototransistors mounted against 24 light emitting diodes, a comparison level phototransistor, digital input/output boards, a personal computer, as well as power supplies. Four different sizes of polymer balls similar to SEEDs in shape and size were employed to test the system, using a completely randomized design method. Treatments were 2, 3, 4 and 6mm (in diameter) polymer balls each of 4 replications. Precision index for any replication in each of the treatments was assessed. SAS software was employed to analyze the data. Analysis of Variance indicated, that, significant differences (P<0.I) existed among different treatments. Means comparison test of treatments showed significant differences (P<0.I) between 2mm (in diameter) treatment and other treatments. System precision for SEEDs of 3mm diameter and bigger ones was 99.5% while for SEEDs of 2mm diameter it was 95.5%.
