The DS18B20 is a 1-Wire® temperature sensor manufactured by Dallas Semiconductor (acquired by Maxim Integrated). Because it is a 1-wire device, it only needs one digital pin to communicate with the microcontroller. The sensor is typically available in two form factors. One comes in a TO-92 package, which resembles a simple transistor.. Applicable Sensors Wiring Diagram Temperature Sensors (Kelvin) Key Details Tolerance = ±4 °C (typical); ± 9 MAX Tolerance = ±2 °C at 25 °C (typical); ±6 MAX Measurement Range = -40 °C to 100 °C (233.15 K to 373.15 K) *Current supply can be IEPE, but must not exceed 5 mA *Temp out is a voltage output referenced to COM (-)
