Lifely Agrumino Lemon -Pocket Weather Station -

Another simple project with Lifely Agrumino device.

Before getting started make sure doyou have

1 Agrumino Kit

1 Micro usb cable for upload sketch with Arduino Ide

1 Adafruit BME680

1 Cable 4 pin Male Jumper to Grove 4 pin

1 Breadboard

Setup Page https://bit.ly/3qgYQ43

Step 1: Description and Connection

In the first you need to connect Agrumino Lemon like a Fritzing example

This will allow us to acquire data with high precision:

• Temperature (° C)
• Humidity (%)
• Atmospheric pressure (hPa)
• VOC (KOhms)
• Altitude (Mt +/- 10Mt accurancy)
• Air quality

Typical applications of use bme680 sensor:

• Indoor air quality
• Home automation and control
• Internet of things
• Weather forecast
• GPS enhancement (e.g. time-to-first-fix improvement, dead reckoning, slope detection)
• Indoor navigation (change of floor detection, elevator detection)
• Outdoor navigation, leisure and sports applications
• Vertical velocity indication (rise/sink speed)
• Handsets such as mobile phones, tablet PCs, GPS devices
• Wearables
• Home weather stations
• Smart watches
• Navigation systemsGaming, e.g. flying toys

Step 2: Import Sketch from github link

Now import sketch from link and upload them with Arduino IDE on your Agrumino Lemon

Step 3: Show data on your Serial monitor

Conclusion:

With this simple example you can build a very accurate pocket Weather Station.

You can also connect a small display (I2C) to see acquired data, or send the data with Mqtt to your Smartphone.

This should be seen as the start of your larger project,.

I hope it will be interesting for you !!

Do you have original ideas that you can realize with Agrumino Lemon ???

Write me!!!!

Thank you....

See you soon!!!
