Modbux - calex temp sensor

Hello,

I would like to use temp sensor with arduino uno and modbus communication. Here is what I have:

  1. Arduino uno
  2. Modbus
  3. Sensor

Did somebody try this configuration or somebody knows if this will work.

I found some old topic but there is not much details and the sensor is slighly different what I have.

Link

Any help will be much appreciate.

Regards Pawel

It will work for some usages but as you don't have a display on the UNO I guess you want to transfer the data to a PC. If that's the case, I recommend to use an Arduino with a free hardware serial interface, p.e. Leonardo, Micro or Mega2560.

Hi thanks for your answer.

I have Mega2560 but not sure what this will change. I saw some youtube videos where people using same configuration as I have but usually they were using different sensors than mine.

It has multiple hardware serial interfaces, so you can use one to communicate by Modbus and another one to communicate to the PC.
