A personal weather station using the Arduino Uno, DHT11 sensor and the ESP8266 module. The cloud platform used here is thingspeak.
The link to the weather stations is as follows:
Step 1: Materials Required
1) Arduino UNO
2) DHT11 Sensor
3) ESP8266 Module
4) Breadboard and a few jumpers
Step 2: Connections
1) Connect the ESP Module as per the diagram except for the Tx-Rx pin. Connect them to the pin nos. you've defined in your code. For ex. in my case it was 6,7'
2) DHT11 sensor O/P pin was connected to the A0 pin, and the other two pins to Vcc and GND.
That's it for the connection. Nothing more than that.
Step 3: The Code
The code is very much understandable with comments mentioned beside the line of codes. The link is as follows:
