This method is usually known as “flame rectification.” Many servicers believe the flame sensor takes an active role in proving flame, and because of this, believe the sensors sometimes fail. Let’s ...

Abstract: Wireless sensor networks (WSN) have attracted much attention in recent years due to their potential use in many applications such as border protection and combat field surveillance. Given ...

Abstract: In this letter, a novel multilongitudinal mode fiber-optic vibration sensor is presented. The beat frequency of any two different laser modes is modulated by the vibration signal. The ...

Basically, this program enables the Arduino UNO R4 to connect to an existing WiFi network, so it can send an SMS alert via API when the flame sensor or smoke sensors detects fire and smoke. At the ...

This project demonstrates how to digitize analog temperature signals from an LM35 temperature sensor using Arduino's built-in ADC ... directly from the ADC (analog to digital converter) on an ESP32-C3 ...

Before compiling and uploading the firmware, you MUST configure critical settings. The recommended way is to use the Web Configuration Portal after the first boot. However, you can also set default ...

Arctic sea ice extent through most of April changed very little. Only at the end of the month did extent begin to decline. Because the month started with unusually low extent, however, the average ...
