In recent years, with the rapid development of mechanized coal mining technology, the types and quantity of explosion-proof combination switches in coal mines are increasing. Based on the analysis of ...

Impact of temperature and process variations on the output voltage variations of CMOS photo sensor is discussed. As temperature becomes high, output voltage (Vout) decreases because of the amplifier ...

Note. A compact analogue reflectance sensor such as the CNY70 was not used in the Arduino Uno experiments described. Instead, a homemade sensor was assembled using a single infrared LED (IR333C) and a ...

The temperature sensor degraded in phosphate-buffered solution over 48 days, leaving the encapsulation layer. This study provides insight into enhancing the sensitivity of temperature sensors with ...
