Berta H10 - LoRa low-power fast prototyping system

Create your own battery-free energy-harvesting solar powered LoRa sensors in minutes with this fast prototyping system

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

  • BATTERY-FREE
    the energy is stored on a 50 Farad VINATech hybrid capacitor 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.

  • VERY LOW POWER CONSUMPTION
    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.

  • HIGH QUALITY SOLAR PANELS
    We have selected the best panels on the market and designed the best circuits to optimize their perfomance.

  • CUSTOM POWER CIRCUITS
    We designed from scratch the power charging section to collect energy even at extremely low brightness levels (50 LUX).

  • CUSTOM DESIGNED ISM ANTENNA
    To achieve maximum transmission efficiency, a highly optimized PCB antenna was designed completely from scratch

  • SENSORS AT STATE OF THE ART
    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.

  • FULLY OPEN-SOURCE SOFTWARE ENVIRONMENT
    The software environment proposed by default is RIOT, the friendly Operating System for the Internet of Things. The language used is C. Everything is available under the Open-Source GitHub repositories.
