Weather Station

Introduction

This project includes an Arduino-based weather station, an ASP.NET Core MVC data presentation page, and an ASP.NET Core WebAPI. The collected data is sent using ESP8266 and written to the SQL Server database via WebAPI. The weather station consists of the following parts:

  • Arduino Nano
  • Nano Shield
  • BME280 - Temperature, Humidity & Pressure Sensor
  • AM2320 - Digital Temperature and Humidity Sensor
  • BMP280 - Barometric Pressure and Altitude Sensor
  • ML8511 - UV sensor (Abandon)
  • GP2Y1010F45 - Optical Dust Sensor
  • DS3231 - RTC
  • ESP8266 - WIFI
  • SD card module
  • 18650 Li-ion and Charger (Optional)

Most of the referenced libraries come from Adafruit and Aduino Playground, and some I don't know who written it. AM2320 comes from thakshak.

How to Use

Connect sensors to Arduino.

In ASP.NET Core

  1. Open "WeatherStation.sln" and rebuild solution

  2. In project Utility, open WeatherContext.cs, change connection string

  3. In project API, open Controllers - WeatherController.cs, change token

  4. Open Tools - NuGet Package Manager - Package Manager Console, change Default project to Utility

    in PMC run this

    PM> Add-Migration Initial
PM> Update-Database

    or run this SQL (PostgreSQL script)

    create database "WeatherStation";

create table weather (
    weather_id           SERIAL not null,
    date_time            TIMESTAMP            null,
    weather_name         VARCHAR(10)          null,
    temperature          NUMERIC(4,2)         null,
    humidity             NUMERIC(4,2)         null,
    pressure             NUMERIC(10,2)        null,
    dust                 NUMERIC(4)           null,
    uv                   DECIMAL(4,2)         null,
    constraint PK_WEATHER primary key (weather_id)
);

insert into "public"."weather" ("weather_id","date_time","weather_name","temperature","humidity","pressure","dust","uv") VALUES (1, '2019-01-01 21:00:00', NULL, -0.90, 25.80, 103662.72, 0, 0.01),(2, '2019-01-01 22:00:00', NULL, -1.50, 28.80, 103729.69, 0, 0.01),(3, '2019-01-01 23:00:00', NULL, -2.20, 29.60, 103632.05, 0, 0.01),(4, '2019-01-02 00:00:00', NULL, -2.90, 31.80, 103884.52, 0, 0.01),(5, '2019-01-02 01:00:00', NULL, -3.60, 33.80, 103603.38, 0, 0.01),(6, '2019-01-02 02:00:00', NULL, -3.50, 32.80, 103704.99, 0, 0.01),(7, '2019-01-02 03:00:00', NULL, -3.10, 31.20, 103872.41, 0, 0.01),(8, '2019-01-02 04:00:00', NULL, -2.70, 29.20, 103882.69, 0, 0.01);

  5. Publish API, WebPage to your server

In Arduino

  1. Copy libraries to x:\Program Files (x86)\Arduino\libraries

  2. Open "WeatherStation.ino"

  3. In Line 134, replace your WIFI name and password

  4. In Line 139, replace your server address and port

  5. In Line 150, replace your Token

  6. In Line 155, replace your Host

  7. Upload program to your Arduino
