Abstract: This paper presents a passive wireless sensor for simultaneously and remotely measuring pressure and temperature under harsh environments. The sensor consists of a dual LC (inductor and ...

The micro sensor showed quick, stable, and high sensor responses to toluene at ppm (parts per million) concentrations at 300 °C even by operating the micro heater in a pulse-heating mode where ...

Abstract: We report on what we believe to be the first truly distributed fiber vibration sensor based on pulse base Brillouin optical time-domain analysis (BOTDA). The pulse base approach is used to ...

This makes the Arduino send SMS, even though it doesn't use any GSM modules at all. Here, to send SMS alerts, I am using the Circuit ... sensor 6 #define Green_led 3 #define Red_led 5 #define Buzzer 4 ...

The complexity here is that we need to fix the circuit in a mobile and remote place—the helmet. So, simplifying the circuit is most important to make it compact and reliable. The circuit diagram ...
