I have been contacted by Tony Powell (tony@enviro365.org) regarding their need for someone to do some Summer work on an IoT project. The have set an initial deadline for expressions of interest March 14th. They are based on the Aber Innovation Campus.

As discussed we are looking to undertake the following and have the need for a programmer to progress the sensors as follows :

Project Profile. (Aqua Eye)

An esp32 based microprocessor that communicates over LoRaWAN.
The Microprocessor has a range of sensors below feeding information through a dac converter.
The output is then forwarded via WAN to a front end web page where the data can be read

Our requirements

Looking for someone with experience of LoRaWAN and C++ that can take our outputs which we currently have running from the processor displayed on screen via Ardunio IDE and programme the device to output via lowran to the web as a readable format.

The sensor types and manufacture name are identified below

DF Robot – Analogue to Dissolved Oxygen (DO)Sensor
DF Robot – Total Dissolved Solids (TDS) Sensor
Optical Turbidity Sensor
PH Sensor
Phosphate Sensor
Nitrate sensor

What we have achieved to date

Providing a coms route from an esp32 outputting through SMS on alarm conditions. But for this project we would like to use a base station and LoRaWAN to reduce the costs of sim cards as part of the system.

Future Scope

To date we are finding it very difficult to get someone with experience and therefore are looking for a long term commitment once we have the initial program sorted to help develop the range of sensors as we expand.
