Hello all, new forum user here.
I am trying to get a LuminOx optical oxygen sensor, found, with data sheet at:
http://www.sstsensing.com/Products/Gas-Sensors/Oxygen-Sensors/LuminOx-Optical-Oxygen-Sensor/188
To give data to my Arduino Uno. The data sheet says that the sensor responds to RS232 commands, but the Arduino uses TTL? I have no idea where to start, in both sending commands to this sensor, and receiving the data. It maybe important to note that the final intention is not to interact with the sensor via a serial link to a computer, as the end system needs to be free standing. I have researched max chips that may be able to help, but having never really attempted anything in this field before I would really appreciate any basic advice or ideas of how this might be achieved. (also I have an ethernet shield to store the data to a micro SD if that is important in anyway)
Thanks in advance
