![]() ![]() Like other photovoltaics systems, the current generated by LAYER® is strongly dependent on the amount of available light. – Use a LAYER® that generates enough tension (either Demokit6 or Demokit11) – Design your power back up such its tension allows functional use (min. – Have a power backup like rechargeable batteries or supercapacitors. Keep in mind that to power such device you need to: The supercap recharges in less than 2mn when exposed to light (1000lux), once charged it allows up to twenty ON/OFF. For this demonstration, we used a 5V – 0,047F supercap. Harvest light with LAYER® and power your LoRa Tap switch. Harvest ambient light to power LoRa tap switch When the light level is enough (More than 200 lux) you will be able to receive data updates every 2-3s. ![]() The board features various sensors including temperature, humidity, air pressure, and a 3-axis accelerometer. Harvest light with LAYER® and get an autonomous IoT device by plugging or OPV modules into the RSL10 Solars Sens Gevk board and retrieve real-time data on the “RSL10 Sensor Beacon App”. Real time data with an autonomous ON Semi board This device is characterized by its very long autonomy: when there is sufficient sunlight (enough power generated by LAYER® to compensate for the consumption of the electronic components), the supercapacitor is recharged, when the sunlight is too low, the energy stored in the capacitor allows transmissions to continue. The latter is used to manage the LoRa chip and the various sensors. The module recharges a CapXX supercapacitor (1.2F – 5.0V) which then powers the E-peas harvester (AEM10941). This demonstrator is composed of an 8-band LAYER® module specially designed and produced for this project. We’ve launched a few months ago a youtube playlist called « Powered by LAYER® » presenting some quick and dirty programs with our close partners : LoRa sensor with e-peasĭracula Technologies and e-peas have developed a demonstrator that allows the reading of temperature, humidity, and pressure data and the transmission of this information via the LoRa protocol. ![]()
