Berta H10 is the main component of a fast prototyping system designed to create your own energy harvesting LoRa sensor device:

* <strong>BATTERY-FREE</strong><br/> the energy is stored on a 50 Farad [VINATech hybrid capacitor](https://www.vinatech.com/eng/product/lithium-capacitor.php) with low self-discharge and a wide operating temperature range. H10 device can be left in standby mode without any light up to 100 days waiting for input or timing events to wake up and transmit data.

* <strong>VERY LOW POWER CONSUMPTION</strong><br/>
Just 4.29 µW (microWatt) in standby mode and 66 mW (milliWatt) in transmit mode allow the devices to remain operational for an extended period, even in total absence of light.

* <strong>HIGH QUALITY SOLAR PANELS</strong><br/>
We have selected the best panels on the market and designed the best circuits to optimize their perfomance.

* <strong>CUSTOM POWER CIRCUITS</strong><br/>
We designed from scratch the power charging section to collect energy even at extremely low brightness levels (50 LUX).

* <strong>CUSTOM DESIGNED ISM ANTENNA</strong><br/>
To achieve maximum transmission efficiency, a highly optimized PCB antenna was designed completely from scratch

* <strong>SENSORS AT STATE OF THE ART</strong><br/>
All the ACME sensor proposed have been selected among those that represent the state of the art in terms of performance and low power consumption. Each ACME Sensor port can be completely turned off. 

* <strong>FULLY OPEN-SOURCE SOFTWARE ENVIRONMENT</strong><br/>
The software environment proposed by default is [RIOT](https://www.riot-os.org/), the friendly Operating System for the Internet of Things. The language used is C. Everything is available under the Open-Source GitHub repositories.
