The Design for Development sector, particularly in the area of clean cookstoves and fuels, has called for better monitoring tools to evaluate and promote impacts of new products. This paper presents the development and testing of the FUEL sensor designed to meet this need. A multi-site, longitudinal case study that used a mixed-methods approach was employed in Guatemala, Honduras, and Uganda to evaluate technical feasibility, system usability, and market value. We found that triangulation of ethnographic and sensor-based data improved our certainty of results, which indicated acceptable technical performance, high usability, and potential market fit. Theoretical discussions include the prevalence of pro-innovation bias and ethical considerations. Broadly, this study encourages the design community to incorporate sensor-based data and rapid ethnographic methods in Design for Development.

发展设计部门，特别是在清洁炊具和燃料领域的发展部门，要求使用更好的监测工具，以评估和促进新产品的影响。本文介绍了旨在满足此需求的FUEL传感器的开发和测试。在危地马拉，洪都拉斯和乌干达进行了使用混合方法的多站点纵向案例研究，以评估技术可行性，系统可用性和市场价值。我们发现，对人种学和基于传感器的数据进行三角剖分可以提高结果的确定性，这表明可接受的技术性能，高可用性和潜在的市场契合度。理论讨论包括赞成创新的偏见和伦理考虑。宽广地，
