20200108· Thermopile is the sensor that consists of several thermocouples usually connected in series or parallel in order to create readable current or voltage when thermal (heat) is applied on it. In nature, electric voltage is created when there is a temperature difference in 2 junctions of dissimilar metal conductor. It is called Seebeck effect. It is due to electron energy levels shifted ...
When power ON this security system, The Nodemcu board connects to the interface created in the Blynk app via the Blynk cloud. Then the system should be activated by the button created in the Blynk app interface. In this case, when a gas leak occurs, it is detected by the MQ2 sensor. Then the buzzer and LED are activated. At the same time, it notifies your smartphone via a push notification ...
