Show Temperature and Humidity as WiFi SSID with ESP8266 and DHT22 Sensor

   I use informations from article Show Temperature and Humidity as WiFi SSID with ESP8266 and HTU21D Sensor, just change sensor. Instead HTU21D, I use DHT22 (AM2302), my schematic is
   I program NodeMCU development board (work any development board with ESP8266: Lolin, Adafruit, WeMos, etc) with Arduino IDe software, using dht_custom_ssid_exp8266_1.ino sketch.
   For frogram ESP8266 as Arduino must follow steps from เพิ่มบอร์ด ESP8266 ใน Arduino IDE (or from my article named Placa NodeMcu v.0.9 programata in Arduino IDE).
  Also, you need 3 library:
- DHT
Pstring
Streaming
   Now, we can find Wi-Fi network with custon name (ESP8266 is in AP mode):
- on Android phone
- on PC with Windows 7
   Name of SSID will change at every 10 seconds, but best view is in Android phone (quick change).
   I made Show Temperature and Humidity as WiFi SSID with ESP8266 and DHT22 Sensor video to see how this system work:
