The Sequans/e-peas demonstration shows the e-peas AEM10941 IC transferring energy from a photovoltaic harvester to a storage element and then to Sequans’ Monarch LTE-M/NB-IoT module where it powers a sensor device measuring power, light and humidity.
The demo kit is supplied with a small indoor DSC photovoltaic cell that can power many types of IoT applications using indoor light and LTE connectivity.
In an outdoor environment, the size of the photovoltaic cell can be reduced to allow for energy-autonomous devices in an even smaller form factor.
In a typical application, such as in farming or industry, device sensors collect data (humidity, temperature, air quality) while the lighting environment is loading the capacitor.
With the combination of the e-peas AEM10941 IC and Sequans’ Monarch module, the collected data can be sent up to 8 times a day, with no need of batteries using a 15cm2 indoor photovoltaic cell under 500Lux, making the devices completely energy self-sufficient and CO2 neutral.
Sequans and e-peas are offering a reference design with schematics for IoT companies, enabling them to design and build their own connected IoT devices using energy harvesting technology.
