A portable sensor for rapid lead detection in drinking water empowers communities to monitor contamination effectively and ...

Abstract: In this work, a capacitive signal conditioner of a CMOS integrated capacitance-to-frequency converter with digital compensation circuit designed for sensor interface applications is newly ...

A ±1,300-V/μs output slew rate into capacitive ... constraints on the PCB layout. Many operational amplifiers (op amps) are used at low signal levels—think of sensors or even RF preamplifiers.

The E-Tongue works by applying a voltage to a water sample, causing any lead ions present to stick to the sensor’s gold electrode ... EPA’s maximum allowed level of 10 parts per billion ...

Detecting the water level inside of a macrophyte constructed wetlands, using a capacitive sensing element, allows knowing the operating state and efficiency of this infrastructure. The energy ...
