I have a temperature sensor which provides output over RS485. However it's not Modbus, its ASCII over RS 485.
I want my Arduino Mega to read data from the sensor.
The sensor works perfectly when I send commands on terminal program. e.g when I send a command ?T asking for temperature value, it responds by answering !T28 i.e 28 Deg C.
I intend to create a temperature display using Arduino.
Would appreciate any help related to hardware selection & coding!
