In this tutorial, we have combined the use of the GSM technology, the MQTT communication protocol and environmental sensors. Practically speaking, we have created a tiny weather station that can provide accurate weather conditions which can be deployed anywhere with GSM coverage.

>**Tip:** As the hardware (MKR GSM 1400 + MKR ENV shield) are both designed to consume little power, we can get creative with the [ArduinoLowPower](https://www.arduino.cc/en/Reference/ArduinoLowPower) library to deploy a complete standalone weather station. The MKR GSM 1400 can be directly powered with a 3.7V LiPo battery with a JST connector.

Feel free to explore the [MKRGSM](https://www.arduino.cc/en/Reference/GSM) library further, and try out some of the many cool functions in this library. You can also check out the [MQTT](https://github.com/256dpi/arduino-mqtt) repository on GitHub.

### Making Sender Device Mobile

As of now, we have a quite immobile setup, but this can be fixed by making the sender device mobile. A good way of testing this out is to make the sender device run on a battery instead. The MKR WAN 1310 has a battery connector that any battery with a JST connector can connect to. A standard 3.7 LiPo battery can power the MKR WAN 1310 for a longer time.

The first step is to connect the board to a source of energy, this can be your computer or a phone charger. In both cases there will be a cable that ends with a micro USB that goes into the MKR WiFi 1010 socket. A standard 500 mA supply is ok and will charge your battery in a number of hours that is proportional to the capacity of the battery. The circuit is designed to provide 4.2V and 512 mAh; with a typical C/2 charge/discharge rating of the cells, this is the reason why we suggest a 1024 mAh minimum capacity. The hours taken for the charge are therefore the capacity divided by the charging current. You can find batteries with different C values depending on their chemistry and application, but the ones available for powering microcontroller boards are usually rated at C/2. Operating the Li-Po battery within its specs will grant it a long and cool (no heating) life.

When the battery is charging, you will see the charging LED lit. When no charge is going on, either because the battery is full or the charging timeout has been reached, that LED is off while the Power LED stays on.
