Tracker or Sensor under 20 euros


Achieving Low-Cost Tracker and Sensor Design for Large-Scale Production

Designing a tracker or sensor for under 20 euros with a production forecast of 1 million units is entirely achievable using various wireless technologies, including NB-IoT, LTE-M, LTE, Mioty, Sigfox, and LoRaWAN. Our team has the experience and expertise to make this possible, as demonstrated by our successful creation of the Gillette order button. This device, which costs less than 20 euros (including VAT), features a 20-year standby time and includes an order button within a waterproof plastic enclosure, a razor blade holder, razors, 3 AA cells, and a SIM card.

Cost-Cutting Measures

Achieving such a low cost involves several strategic measures. Using a 2-layer PCB reduces manufacturing expenses, while optimised code ensures efficient operation. An 8-bit MCU serves as a timer, further cutting costs. The use of assembler code on the MCU and a 0 Euro PCB antenna significantly decreases overall expenses. These cost-saving strategies do not compromise the device’s functionality or reliability, making it both economical and highly effective.

Technical Feasibility and Scalability

From a technical standpoint, this approach is entirely feasible. Although we produced only 22,000 Gillette buttons annually, scaling up to 1 million units opens new opportunities for cost reduction. At such volumes, we could move to the chip level, potentially eliminating the 8-bit MCU and achieving a 10-year standby time. Furthermore, equipping the SIM card with positioning functions could replace the need for GPS, streamlining the design and reducing costs even further.
