Working of DS18B20 Temperature Sensor Module

1 wire communication method is used to communicate with DS18B20 sensor. It works with the data pin connected with pull up resistor with microcontroller and other two pins are used for power, one for positive and another for negative voltage. When the bus is not in use a single pull up resistor is used to keep the signal line in high order state. Internal storage of sensor is used to store the temperature which is 2-byte. To read the temperature 1 wire method is used to send the command and in return values are passed back to the microcontroller. Each DS18B20 sensor has 64 bit serial code which offers large numbers of sensors to connect on single line, means we can connect many DS18B20 sensor in the same single one wire and the same data line is used to communicate with single microcontroller.

 

  • The sensor reads and converts the temeperature and stores this temperature value in a memory.
  • The memory is read via the 1-wire bus by the DALLAS library.
  • 64 bit serial code offers multiple sensor to connect on a single line. It assigns different addresses to all sensors attached and by calling the address, you can get that sensors’ reading.
  • Digital Output: Temperature in Celcius readings.
