I am using NodeMCU for coding for purpose. I am trying to get input from web browser & update the Input value.
I am using DHT11 sensor here. i could able to display temp & humidity. Now i want to set unique temp It should get updated in set value
This part create text box and set to take input from externally. Now these has to take input & store it in Set_Temp how can i store it.
