I am doing a project in which I have connected a temperature,humidity,and MQ2 sensors.This is my code snippet:
But when I checked the variable description,the context field was empty. I don’t know what’s wrong with this code.I used the library “UbidotsMicroESP8266.h”.There is no GPS on my device.
My project presentation is on this week.I don’t know what to do. Can anyone help me with this please?
