Abstract: We have implemented LTCC (Low Temperature Co-Fired Ceramics) based packages for all solid-state electrochemical hydrogen sensor modules. The hydrogen sensor utilizing a solid electrolyte is ...

Arduino project for receiving and (in the future) transmitting signals using a 433 MHz RF module. Currently, this repository contains code for a 433 MHz signal receiver, which allows reading signals ...

Abstract: Here, a compact multigas sensor using tunable diode laser absorption spectroscopy (TDLAS) combined with the spectral matrix compensation (SMC) method is developed. Each gas measurement unit, ...

When the first laser and inkjet printers for PCs arrived in the mid-1980s, they could only print in monochrome, and their respective advantages were obvious. Today, the differences between laser and ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...
