In previous papers to this SPIE forum the development of novel technology for next generation PIR security sensors has
been described. This technology combines the mosaic pixel FPA concept with low cost optics and purpose-designed
readout electronics to provide a higher performance and affordable alternative to current PIR sensor technology,
including an imaging capability. Progressive development has resulted in increased performance and transition from
conventional microbolometer fabrication to manufacture on 8 or 12 inch CMOS/MEMS fabrication lines.
A number of spin-off applications have been identified. In this paper two specific applications are highlighted: high
performance imaging IRFPA design and forest fire detection. The former involves optional design for small pixel high
performance imaging. The latter involves cheap expendable sensors which can detect approaching fire fronts and send
alarms with positional data via mobile phone or satellite link. We also introduce to this SPIE forum the application of
microbolometer IR sensor technology to IoT, the Internet of Things.
