DS18B20 digital temperature sensor 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 of the liquid crystal in 1602. At the same time to determine whether the temperature exceeds the upper and lower limits, If exceeded, the LCD screen will prompt flashes. 2, experimental operation 1, the LCD1602 LCD insert J15 socket pin liquid injection direction. 2, by adjusting potentiometer VR2 can change the contrast of the display. 3, the jumper socket J11 jumper cap adjusted TDQ end. If the jumper is not set correctly, the LCD screen will display No DS18B20.
