| A capacitive sensor method for measuring billet spacing uniformity with sugarcane (Saccharum officinarm L.) billet planter is investigated in this paper. Therefore, an electronic device based on capacitive sensor was designed and developed to predict the planting spacing of sugarcane billets. It consisted of four components: a rectangular parallel plate capacitor, electronic circuitry, microcontroller, and display unit. Accordingly, a prototype of the precision metering device for sugarcane billets was developed. After calibrating the monitoring system, the results were verified with calibrated curve by means of linear regression and paired T-test. The performance of the device, including quality of feed index (QFI), multiple index and miss index was... |
