1-wire thermal sensor
The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements.
It communicates over a 1-Wire bus that by definition requires only one data line (and ground)
for communication with a central microprocessor. It has an operating temperature range of
-55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to
+85°C.
Lines used as 1-wire bus:
| Aria pins | Signals |
|---|---|
| S1 | 3V3 |
| S2 | 1-wire data |
| S24 | GND |
