Reading Temperature With Arduino
Most PLCs nowadays cost a lot of money, especially the ones with temperature inputs, generally ranging from $50 to $250. With an Arduino it is very easy to read temperature with a few cheap components.
Supplies
Light Sensor-Amazon
Arduino Nano-Amazon
Attach the Thermistor
Remove the light sensor on the module a replace it with a thermistor. I used a 0-200°F thermistor.
Wire the Board
wire the sensor module onto any Arduino board. The example shows a different module but the connections are the same.
Program the Arduino
Finally, you can upload this simple sketch to the Arduino to read the temperature.
