fire security alaram with controlling fan

components required::

1. NodeMCU ESP8266
2. Micro USB Cable
3. Fire Sensor // IR Sensor
4. Jumper Wires
5. Buzzer
6. Breadboard
7. LEDS
8. Power supply 9V battery
9. Fan
10. Relay module

working:: Make the connections as given in the circuit diagram. Then upload the code in NodeMCU using Arduino IDE . The fire sensor is connected at D1 pin to give the digital input to the NodeMCU and Buzzer is connected at D2 pin to get digital output from the NodeMCU. Relay 2 channel is connected at D4 pin to get digital output from the NodeMCU. If fire is detected by the fire sensor then it gives “0” and NodeMCU turns on the buzzer, fan attached to relay and sends notification to the mobile else it can send email to the attached mail address.
