The endrich IoT Ecosystem combines sensor technology, intelligence, wireless technology and cloud connectivity with open source support. The heart of the system is the Endrich IoT Board v52, developed in-house. This is equipped with various sensors, a microcontroller with RISC-V architecture, LTE-M/NB-IoT technology and several options for controlling and monitoring other applications. An LTE-M/NB-IoT modem with antenna is integrated. This allows data to be connected to the cloud using standard protocols such as MQTT/CoAP/LWM2M PPP/TCP/UDP/HTTP(S). Direct communication with the endrich IoT Board is possible via I²C, SPI & GPIO and UART. 

The endrich IoT Board collects and processes a wide range of data. The vibration sensor detects vibrations in order to signal a machine run, detect the engine start or generally monitor an engine run. It can also be used to detect rain or the intrusion of people into a building. The air pressure sensor is suitable for height measurement, also to detect height differences in the centimetre range. Another sensor measures the fan speed or records the speedometer signal. The ALS sensor, which operates in the sensitivity range of the human eye, detects light and dark conditions and measures the visible light intensity. GNSS coordination can be used to determine the physical location of the unit or to track a unit. Ambient temperature is measured via a temperature sensor. 

The Endrich cloud database is available for data visualisation and evaluation. The UDP cloud data is displayed in a messaging log as well as in a customised visualisation tool. The cloud database can be used freely for testing purposes during development. With external partners, it is planned to expand the offer and provide different cloud databases, e.g. based on MQTT, with different visualisation options. Larger cloud systems such as Azure or AWS are also supported in order to integrate IoT solutions into existing platforms.
