£10-15 GBP / hour

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. [login to view URL] 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.
