For the sensor systems, both sensors developed at Fraunhofer EMFT and commercially available sensors are used. Sensor circuits with microcontrollers are designed for this purpose and the "embedded" software or firmware is programmed as required. These developments range from the AFE "Analog Front End" – the conversion into a digital signal via an ADC "Analog Digital Converter" – to the digital processing in the microcontroller and the various interface technologies, both wired (USB, RS232, RS485, OPC UA, CAN, Ethernet...) and "wireless" (BLE – Bluetooth Low Energy, 868MHz solutions, WLAN...).
In the field of sensor technology, complex optical analysis systems are designed to record absorption, chemiluminescence or fluorescence processes at different wavelengths or even an entire spectrum. This allows the analysis of material and surface properties as well as biological substances in agricultural and medical applications. Especially spectral evaluations in the VIS and IR range provide extensive information for a wide range of applications.
