Weather Station IoT system - Realtek Ameba RTL8195

Descriptions

IoT-ready device (Ameba RTL8195) is applied in real-life scenarios. If you have watched my previous examples, you should have no problem understanding how an LCD display, a DHT Temperature Humidity sensor and our Ameba dev. Board can be put together to form a fully functional smart weather station. Simply follow the instructions in our examples as follows to DIY your own weather station,

1. LCD 24H Clock,

2. MQTT,

3. DHT+MQTT,

The key to integrate these 3 examples successfully is to make sure that you have set up your MQTT server correctly and note that here we are using a different set of MQTT topics, namely “dht_data” and “dht_status”. Also, when connect DHT sensor, D13 pin is used as data input pin.

With this smart weather station, you may,

1. Check real-time temperature and humidity from the LCD display

2. Receive warning message when abnormal humidity (higher than 80%) is detected

3. Query your home/office humidity and temperature on-the-go

Step1

Finish up all hardware connections. There are two side Weather station side and client side(hand-phone)

refer to https://github.com/Realtek-AmebaApp/Ameba_Examples/tree/master/RTL8195AM/004_WEATHER_STATION

Step2

Download Arduino IDE, install Ameba RTL8195 board.

refer to https://www.amebaiot.com/en/ameba-arduino-getting-started/

Upload the ino code into board from Step1.

Weather_Station_LCD_DHT_MQTT.ino (from Github link above)

Step3

Hand-phone side. Install the APP MQTT client. And use it to test the preference of the weather station.
