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.

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
