UppSense

UppSense17- Open Source sensor for chemical analysis based on fuoresence.

Hardware

Hardware Block Diagram

The hardware consists out of three PCBs so far: An analog PCB, a digital PCB and an active Backplane. Two PCBs are developed with KiCAD. One is developed with Altium.

A transimpedance amplifier is used to convert light into a voltage. With a second stage this voltage is amplified. Both outputs are available for the ADC.

On the digital board there is besides an ESP8266, an ADC, a DAC and a temperature sensor. The DAC is needed to steer the LED driver circuit, that excites the sample.

Software

UML Diagram

The software is written in C++ leveraging the Sming framework. This enables IoT applications very easily.

In the UML diagram above it is examplarily shown how the software works. Providers and receivers can be tied together in pairs to enable an easy way to exchange data.
