One seismometer is often not enough to reliably detect earthquakes or human activity such as underground nuclear tests.

Abstract: Electromagnetic tomography technique has been developed for monitoring the electric conductivity and/or magnetic permeability distributions in industrial applications. It offers some ...

Using the Arduino ADC and DAC features to realize a full-fledged multichannel anayzer with only a few common components allowed to operate a used NaI scintillation counter (from Ebay) and compare the ...

There are plenty of -232H series breakout boards, but they are generally designed to be an easy way to adapt it to a specific use, and not designed for regularly plugging in to all different target ...

Using a small custom PCB, a Raspberry Pi Pico 2 microcontroller, a scintillator (typically NaI (Tl)) and SiPM you can build your own gamma spectrometer! The needed processing and multi-channel ...

Surface Acoustic Waves (SAW) sensors are known to be an excellent choice for the measurement of a small concentration of analytes in gas mixtures. The use of this type of sensor has been limited until ...

This low-cost portable spectrum analyser can be used to analyse the frequency content of input signals up to 5kHz. Frequency spectrum of an input signal possesses vital information, and the same has ...
