Hoping to heighten motion sensitivity in building automation, ST has released a lens-free IR sensor with micromachined thermal MOSFETs. STMicroelectronics recently announced a new IR sensor using thermal MOSFETs (TMOS) in the place of lenses and passive IR pixels. ST claims the space savings afforded by the TMOS technology may help designers improve performance and conserve board real estate for densely-integrated designs. ST’s latest IR sensor uses a completely different sensing mechanism without an IR lens. Image (modified) used courte...
