H10 - An extremely low-power System On Module designed for energy harvesting LoRa radio sensor applications

This new module designed by Acme Systems enables the creation of a new range of battery-free solar-powered radio sensors with unprecedented features

H10 includes all the circuitries requested to:

  • collect the energy from a small solar panel
  • store the energy on a small hybrid supercap
  • manage a selected set of low-power sensors using different data buses
  • save the data collected
  • send and receive data via a Lora Radio in ISM band

An original power circuitry is able to charge the supercap with less than 50 LUX avoiding any power loss in no-light conditions.

All the parts requested to build a complete solar powered radio sensor are available from this site:

  • Antenna
  • Hybrid supercap
  • Solar panel
  • SOM
  • Devkit
  • Gateway
  • Sensors

The application examples and drivers are released under Open Source licence and is based on RIOT the friendly Operating System for the Internet of Things

A complete set of software examples and articles are provided to shown how to the system works.

The policy for transmission intervals is completely customizable by the user from the gateway side.

Automatic transmission power reduction of the sensor nodes based on reception signal strength further enhances their capacity of reliably operating in environments with extended periods of no light conditions.

The nodes have the capacity to continue transmitting for weeks in reduced or no light conditions by automatically reducing the number of messages transmitted per hour. The supercapacitor can be fully recharged after just 15 minutes of outdoor light exposition.
