Monitoring Weather Data using BMP280 and Blynk 2.0

Monitoring weather data is an important part of meteorology. Weather data is used to monitor the atmosphere, to forecast weather conditions and to monitor climate change. Meteorologists use a variety of weather data to make predictions. So we came up with an idea of building a small weather station which will be monitoring weather data using BMP280 and Blynk 2.0 app and over web dashboard.

Weather data can be collected from a variety of sources. Air pollution data can be used to monitor air quality. Satellite data can be used to monitor climate change. Weather data can also be collected from weather stations, which are located all over the world.

Weather data is used to make predictions about the weather. A meteorologist can use past data to make predictions about the weather in the future. Meteorologists can also use data to make forecasts. A forecast is a prediction about the weather in the future. A meteorologist can make a forecast about the weather for a specific location or for a entire country. Scientists use weather data to monitor the atmosphere. The atmosphere is the layer of the Earth that contains air.

Parts List

For building this project you need below items.

WeMos D1 Mini x 1
BMP280 Sensor x 1
Jumper Cables
Laptop and Data cable

BMP 280 Sensor

BMP280 is a small and powerful sensor that has been designed specifically for small devices. One of the key features of the BMP280 is its ability to measure temperature, pressure and altitude. This makes it ideal for applications such as security and surveillance, as well as environmental monitoring. Another advantage of the BMP280 is its low price point. This makes it a suitable option for a wide range of applications, including consumer devices and embedded systems.

Working

The data will be collected by BMP280 sensor and sent to WeMOS D1 Mini which is a ESP8266 based development board. This development board will send the data to Blynk cloud servers which will be displayed in web dashboard and in Blynk mobile app.

Connection

Connect the sensor with WeMos D1 mini module as shown below.

Blynk 2.0 Configuration

Add details for your New Template and click on Done.

Now click on Datastreams and click on New Datastreams

Select Virtual Pin and proceed.

Fill in the Virtual Pin Details as shown below for Temperature and click on Create. Similarly create for Pressure and Altitude.

Once Datastreams are created you can see them listed below as shown and click on Save.

Now lets update the code and upload it in WeMos D1 Mini. Copy the lines shown after creating the template.

Paste it in the code as shown below and upload the code.

Activating or Connecting Hardware with Blynk

Now we will activate the device or hardware using new Blynk app using below steps.

Tap on Connect to Wi-Fi

Tap on Start

Goto Wi-Fi Settings on of smartphone and you will find a Blynk based access point with template name.

Tap on it and connect

Now Blynk app with connect your device with Blynk cloud. It will ask for your wifi details.

It will get connected and give you an option to Continue

Now tap on menu and then tap on Developer Mode

You will see the template is shown here. Tap on it

Tap on the + Icon to add the widgets

Scroll down and select the Gauge widgets

Configure the gauge by selecting the proper Datastream

Code

You can download the entire code from below link and open it using Arduino IDE.

Building & Testing

Once the connection is done as per the connection diagram and all the above steps are completed, then its time to test the project.

You will get the below real-time output in blynk app.

Similarly if you configure the web dashboard then you will be getting the same output there as well as shown below.

Summary

Monitoring weather data can be a fun and informative process. By using a sensor like the BMP280 and integrating it with Blynk 2.0, you can easily collect weather data from a variety of locations. This data can then be used to monitor weather conditions, forecast weather patterns.

You can use the BMP280 to collect data by building a small weather station. The Blynk app is used to collect data from a variety of sensors, and display it in app or web dashboards. Hope you like this tutorial and don’t forget to share this tutorial.
