Low-Volume, High-Reliability | Industrial Moisture Sensor Case Study

This case study highlights the development of an industrial-grade moisture sensor by IXEtronics, an embedded systems services startup, designed to operate reliably in demanding industrial environments. The product originated from a real-world problem statement shared by a cashew industrialist, leading to a proof of concept (PoC) to detect moisture levels during cashew processing. After successful validation on the shop floor, the industrialist placed an initial order of 100 units with funding support to move the product toward deployment.

To transition from PoC to production, IXEtronics approached us for design validation, enclosure development, and production planning. We analyzed the existing design and evaluated manufacturing options including 3D printing, vacuum casting, and injection molding, comparing cost, tooling investment, lead times, and flexibility. Given the low-volume requirement, high tooling costs, and the need for rapid design changes, 3D printing was selected as the most viable manufacturing approach.

Design decisions focused on functional robustness, enclosure protection, ease of assembly, and long-term durability, while avoiding overengineering. The chosen manufacturing strategy enabled efficient low-volume production, faster iteration cycles, and reliable field deployment—making the product well-suited for industrial use without the risks associated with mass-production methods.

Impact

100+ sensor sets manufactured, each comprising 5 individual components

Manufacturing cost reduced to nearly one-tenth of traditional tooling-based methods

1–2 week turnaround time enabled rapid iterations and field-ready deployment

High flexibility to incorporate design changes without tooling delays or cost escalation
