Job ID: 30658464

Budget: $3,000 – $5,000 USD

I am looking for an expert in hardware design, ideally in the US, who can design a multiparameter instrument with available sensors, which consisters of 4 sensors
- 2 pH sensors,
- 1 EC (conductivity) sensor, and
- 1 Refractometer (brix) sensor.
- Wifi connection
The final product will look like the files attached
I can provide the specs later.
Let me know
