IoT Blynk Email and Push Notifications - Arduino example using ESP8266. VCC is connected to the 5V of the ESP, GND is connected to GND. In order to send data on thingspeak, you have to create a thingspeak account. We will program the NodeMCU to read and store the LDR data into a variable and then upload it to ThingSpeak using its channel name and API key. In the program code, first the standard open-source libraries of Arduino for interfacing LCD and setting up virtual serial communication are imported. We’ve seen other examples of how easy NodeMCU and Thingspeak work to put the mundane on the Internet. ESP8266EX is among the most integrated WiFi chip in the industry; it integrates the antenna switches, RF balun, power amplifier, low noise receive amplifier, filters, power management modules, it requires minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. In this case, go after the analog read first as you try to get going in your NodeMCU v3 - analogRead() conversation. 3-5V for Arduino, NodeMcu, Raspberry Pi. The code checks the state of the Input GPIO0 and when it goes LOW the code knows the use has pressed the push button and wants the relay to be on. Gas Sensor(MQ2) module is useful for gas leakage detecting(in home and industry). 3V but I'm getting nothing read at the serial.
