As in the past the temperature sensor output is ****og, we need to add additional A / D And D / A chip into Line conversion, for Arduino resources are not abundant external interface is a big challenge at the same time utilization is not high. The new DS18B20 Temperature Sensor Module is a good solution for this, it use a unique bus line and economic package that make this sensor a good DIY component,
Negative (-) Pin = connect to Arduino GND
Pin (middle) = connect to arduino +5V
Pin S = Signal, in this example connect to Arduino Digital port 10
When everything is properly connected, there is a led on the module that blinks when the sensor is read.
