80 GHz mmWave liquid level detection sensor supports ModBus, offers 40m range I’ve just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a ...

This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic sensor, LEDs ...

Major challenges remain to precisely detect low-abundance proteins rapidly and cost-effectively from diverse biofluids. Here, we present a gold nanoparticle (AuNP)-supported, rapid electronic ...

Liquid level distance can be determined by the fundamental resonance frequency (RF) or a series of RFs from the acquired acoustic signals using the acoustic resonance-based method (ARM). However, in ...

The rapid and accurate detection of creatinine is essential for monitoring kidney function and diagnosing renal impairments. Nonenzymatic catalysts have been used to improve sensitivity and reduce ...
