Many Linear Technology devices use an external PNP transistor to sense temperature. Common examples are LTC3880, LTC3883 and LTC2974. Accurate temperature sensing depends on proper PNP selection, ...
While sensors and low power actuators occupy the lowliest level of an automation system, they often require a disproportionate amount of time and attention. Historically, each sensor added entailed ...
Researchers have designed a new kind of sensor 1 that can detect minute traces of para-nitrophenol (PNP), a water pollutant. This sensor will be very useful for monitoring the extremely low levels of ...
