Abstract

This study aimed to construct and measure the performance of the microcontroller measuring the blow count and depth of piles. The microcontroller measuring the blow count and depth of piles was constructed and then assessed the suitability. The participants of this study were 20 experts in building construction and pile driving. The instruments used in this study were the Microcontroller which measures the blow count and depth of piles, and the suitability questionnaire. The microcontroller measuring the blow count and depth of piles was determined the performance by comparing with people counting. To assess the suitability of this counting machine, after it was constructed; it was observed by the participants for 3 hours of demonstration and then they evaluated its performance suitability. The data were analyzed using statistical method to obtain the mean scores and standard deviation of the suitability. The results revealed that the microcontroller measuring the blow count and depth of piles had high suitability (x ̅ = 4.42). The completely constructed microcontroller measuring the blow count and depth of piles was finally tested with 60 piles, compared with examining and counting by the experts in pile driving. It showed a 100% accuracy of its performance. Moreover, the experts also gave the interesting suggestions. Firstly, it wasthe outstanding development of engineering skill. Secondly, it should be further developed to be
the model for commerce.
