TTS Weather Broadcast

I usually decide whether to bring anumbrella based on the weather conditions before going out. I used to make wrong decisions because the weather was changeable in the past two weeks，it was sunny when I went out that I didn’t bring an umbrella, and unfortunately it rained when came I back. I have a mind that making a player to broadcast the weather forecast when I go out.

Hardware:

• MakePython ESP32

• USB cable
• PIR Motion Sensor Module

https://www.makerfabs.com/pir-motion-sensor-module.html

• Audio

Software:

• Arduino IDE

connect two boards according to the pins. Power the board with USB cable. the sensor pin connections:

GND --- GND
VCC --- 5V
OUT --- Pin 15

The sensor module has two adjustment buttons, one is to adjusting the delay before firing, the other is adjusting the sensitivity, which needs to be adjusted before use.

• ESP32 Support

Follow the Installation Instructions to add ESP32 support if you are not yet do it:

https://github.com/espressif/arduino-esp32

• Install library

1. Adafruit SSD1306 and dependent libraries.
2. ArduinoJson libraries
3. Install zip library : ESP32-audioI2S ("Audio.h")

You can get the code from here:

(Please use the code of gray branch)

• Setting the WIFI password

//WIFI
const char *ssid = "************";
const char *password = "************";

• Getting the weather API

String weather_request()<br>

You can look for a fee or free API interface on Google, that limits individual users with a number of free API interface most of time.

• Showing weather

void lcd_weather(String cond_txt, String tmp, String hum, String wind_dir)

• Setting the weather icon

void draw_weather(int a)

• Weather broadcast

audio.connecttospeech(text, "en")<br>

• Materials: cardboard (packing box), cutter, pencil
• Fold the cardboard into a suitable size carton, Draw the outline on the cardboard and cut it.
• Put the assembled board into the carton and fix it with tape or filling sponge.
• Decorate carton: Draw and write on the surface of the carton.
• Please place the player where you will pass before going out to ensure that the sensor can sense.
