DS18B20 digital temperature sensor alarm test program 1. Program Description: This example demonstrates the microcontroller port connected to the digital temperature sensor DS18B20 testing laboratory. And displays the current temperature in the digital tube. At the same time to determine whether the temperature exceeds the upper and lower limits, If exceeded, the LED will blink prompted. 2, experimental operation 1, the jumper socket J11 jumper cap adjusted TDQ end. If the jumper is not set correctly, the LCD screen will display Error. When close to heat sources such as electric iron can DS18B20 test until the temperature exceeds the upper limit The LED will blink prompt overtemperature.
