This paper presents the design of a Personal Comfort Node (PCN), a platform for sensing and user interaction, meant to be part of an indoor climate control system that can provide personalized occupant comfort in commercial buildings. The paper describes the lessons learned during the design and prototyping of an individual node. The hardware components are of commercial-off-the-shelf variety and the software design is based on open source tools that are freely available, so that it is possible to replicate the device at low cost. The goal of this article is to aid such replication. The design and testing of a network of these devices, along with their use in real-time control of indoor climate, will be reported in future work.
