pH and conductivity PCB board modbus/rtu
Budget: $15 – $25 USD
Hello,
I’m looking for a professional and experienced PCB designer in order to develop two electronic boards. The first one should be able read high impedance (>1Tera ohms) mV signals from a pH sensor, the communication should be through rs485 modbus/RTU.
The other board project should be for reading conductivity sensors and there is also need a communication port for rs485 modbus/rtu.
