We transform industry 4.0 into more digital with the least environmental impact. We have created the most advanced iIoT devices fully powered by waste heat, wind or solar, for monitoring vibrations, steam leaks and temperatures. Device is batteryless and free of maintenance. Data is processed in the IoT (edge computing) and sent using LoRaWAN or NB-IOT/LTE-CATM to our predictive maintenance cloud platform.
