About this item

• 👉 AIM : In this project, we have used to design an IOT based Gas level sensor using Node MCU by interfacing with Blynk application and level for gas will be shown on Leds. If level increases to high level then red led will glow and if decreases to low level then the green led will glow.
• 👉 NodeMCU ESP8266 CP2102 NodeMCU WIFI Serial Wireless Module : The development board equips the ESP-12E module containing ESP8266 chip having Tensilica Xtensa 32-bit LX106 RISC microprocessor which operates at 80 to 160 MHz adjustable clock frequency and supports RTOS. Operating Voltage: 2.5V to 3.6V On-board 3.3V 600mA regulator 80mA Operating Current 20 µA during Sleep Mode ESP8266 CP2102 NodeMCU LUA ESP-12E WIFI Serial Wireless Module
• 👉 MQ-2 Gas Sensor Module : Operating Voltage is +5V Can be used to Measure or detect LPG, Alcohol, Propane, Hydrogen, CO and even methane Analog output voltage: 0V to 5V Digital Output Voltage: 0V or 5V (TTL Logic) Preheat duration 20 seconds Can be used as a digital or analog sensor The Sensitivity of Digital pin can be varied using the potentiometer
