# Using BME280 sensor with Blynk mobile app

## Overview

This example shows how to use MongooseOS with Blynk mobile framework.

Go to device configuration and specify

`blynk.auth` setting to your Blynk access token. Or, alternatively,

run the following console command (from the terminal or "Terminal" tab in Web UI):

# BME280 sensor i2c address

```bash

# In case its on 0x76 use this

mos config-set i2c.address=0x76

# Otherwise if its on 0x77 use this

mos config-set i2c.address=0x77

```

```bash

mos config-set blynk.auth=YOUR_TOKEN blynk.server="blynk-cloud.com:8442"

```

## Blynk configuration

- Create a graph with virtual pin 1 (Graph of memory usage) limits min 0 - 50

- Create a button with virtual pin 2 (Toggles led on/off)

- Create a graph with virtual pin 3 (Graph of temperature) limits min -30 - 60

- Create a graph with virtual pin 4 (Graph of humidity) limits min 0 - 100

- Create a graph with virtual pin 5 (Graph of pressure) limits min 500 - 3000

You can easily add your own handlers for Blynk virtual pins, in either C

or JavaScript.
