hemical and industrial manufacturing processes often require temperature, humid- ity, and other environmental parameters to remain in a small, fixed range that varies over time [11]. Should the temperature fall outside this range, manufacturers risk costly failures that must be avoided. Thus, they currently employ a range of wired sensing to avoid such problems [25,13]. Interestingly, companies in this area (., GE, Honeywell, Rockwell, ABB, and others) are aggressively pursuing the use of mote-like devices to provide wireless connectivity, which is cheaper and safer than powered so- lutions as motes don’t require expensive wires to be in- stalled and avoid.
