portable low-cost open-source wireless spectrophotometer

Job ID: 35015827

Budget: £10 – £15 GBP

I want to build an portable low-cost open-source wireless spectrophotometer based on the development done by Katrina Laganovska. I want to use her Arduino code and install on an Arduino NANO 33 IOT board to support the transfer of the sensor data over wifi to an external MQTT broker.

I have the hardware and require an experienced Arduino programmer to develop the relevent software changes.

See Katrinas document on how to implement her solution. https://www.sciencedirect.com/science/article/pii/S246806722030016X However I do not want a mobile app or a desktop app, I just need to take the sensor data from the arduio nano iot 33 board and transfer to an MQTT backend broker.
