Review on Split Time Study with Arduino Base Device for the Measurement of Detonation Times in Blasting Caps

Abstract

In the field of explosive engineering, the precise measurement of detonation time is a critical parameter for ensuring operational safety, performance evaluation, and optimization of blasting operations. Traditional systems used for this purpose, such as high-speed oscilloscopes or specialized instrumentation, are often prohibitively expensive and require a high level of expertise to operate. This paper reviews the development, design, and application of an Arduino-based device for measuring detonation times in blasting caps using split time methodology. By employing cost-effective micro controllers, sensor systems, and data acquisition techniques, this approach aims to provide an affordable, portable, and reasonably accurate alternative to conventional systems. The review further examines the strengths, limitations, and future potential of this system in both laboratory and field environments. innovations.

Introduction

Detonation timing is crucial in blasting operations to ensure efficient rock fragmentation, safety, and reduced vibrations. Traditional high-speed timing systems are expensive and often require controlled lab environments, limiting field use. This review explores using Arduino-based microcontrollers as a low-cost, portable alternative for measuring detonation split times in blasting caps.

The study aims to design and validate an Arduino system that records the time between the initiation and explosion events using high-speed sensors (piezoelectric, optical, or acoustic). The system leverages Arduino’s microsecond timing capabilities and is tested for accuracy and repeatability.

Key points include:

• Existing systems are costly, bulky, and not field-friendly.

• Arduino offers a modular, customizable, and affordable platform.

• The proposed system consists of Arduino Uno/Nano, sensors, signal conditioning circuits, data logging modules, and optional display.

• Experimental tests show the system achieves accuracy within ±50–100 microseconds, adequate for practical use.

• The system is lightweight, portable, and costs under $50, making it accessible for researchers, engineers, and field operators.

• Limitations include sensor sensitivity, timing resolution constraints, and data security, with future improvements suggested like higher-speed microcontrollers and wireless data transmission.

Conclusion

The Arduino- grounded outfit offers a feasible, cost-effective, and movable result for measuring eruption split times in blasting caps. Although it does n\'t completely substitute high- end artificial systems, it provides acceptable delicacy for educational, exploration, and specific field operations. The open- source characteristics of Arduino platforms grease ongoing advancements in the sphere of detonics and blasting exploration..
