If you wanted to know the interfacing of DHT22 with NodeMCU and circuit diagram kindly refer this previous video link: th-cam.com/video/BCB1zzRWGF8/w-d-xo.html
Nice idea & video! Thank you! I will make it happen here. How do you see the efforts for running / porting this on / to a ESP32 board? Maybe even with LoRa...
@@electronicsinnovation Thank you. I have worked with NodeMCU interfaced with DHT11 sensor. I wanted how the NodeMCU can be implemented for air conditioner , so that we can control the air conditioner through mobile app from any where in the world through internet.
Air conditioner is already having a sensor in built to sense the temperature, and there is a mechanism to control the AC functions with remote. Since we cannot change the mechanism of communication you can do one thing. You can interface a tiny electrical heater to control the temperature. you can add a wireless communication mechanism (WiFi/Bluetooth) to pass instructions from mobile to Device, thus you can control the temperature. If you need more details on this project you can mail us at askus.electronicsinnovation@gmail.com
Thank you for this ! :) One question, i dont have anything connected to PIN D1 and D3 on the microcontroller and i can send info to thingpeak, everything works, so what is this 'power to sensor' section supposed to do ? thanks! pinMode(D1, OUTPUT); pinMode(D3, OUTPUT); digitalWrite(D1,HIGH); digitalWrite(D3,LOW);

Good video. Well explained
Good video 👍
good info
I'm getting an error "Failed to read data from DHT sensor"

Thank you very much for this clear explanation.
I have a query on ESP 8266 wifi module for smart air-conditioner. Can i post it here?
yeah you can...

pinMode(D1, OUTPUT);
pinMode(D3, OUTPUT);
digitalWrite(D1,HIGH);
digitalWrite(D3,LOW);
It shows "Failed to read from DHT sensor"
