In this paper we present an investigation into using the swept frequency excitation for the inductive metal sensor. The frequency sweep excitation mode allows collecting eddy current data at a wide ...

A temperature compensated magnetic field sensor using magnetic fluid (MF) filled exposed core fiber (ECF) has been proposed to detect magnetic field strength and temperature (MFT) simultaneously in ...

After downloading the library, load the MQ7_Example.ino example sketch onto your device, with analog out connected to A2 GND connected to GND Vin connected to 5V Upload the sketch, and then monitor ...

Following beeps of the detector, they found hidden coins during one of our monthly meetings held on the second floor of Tamaqua American Legion headquarters. So 40 years ago I bought a White’s metal ...

The effects of the concentrations of glutaraldehyde and FeCl 3 ·6H 2 O on the film’s structure and properties have been studied in detail; the results show that the strain sensor prepared from the ...
