ALL ABOUT
Digital sensors
The DS18B20 digital thermal sensor is quite accurate and does not require any external components to operate. It can measure temperatures from -55°C to +125°C with a measurement accuracy of ±0,5°C.
The measurement sensor resolution is user configurable to 9, 10, 11 or 12 bits. However, the default power-on resolution is 12 bits (i.e. an accuracy of 0,0625°C).
This measuring instrument can be powered with a 3 V to 5,5 V supply and consumes only 1 mA during active temperature conversions.
Here are the full specifications of the DS18B20 digital temperature sensor:
Power source | 3 V to 5,5 V |
Power consumption | 1mA |
| Temperature page | -55 to 125 ° C |
| Precision | ± 0,5 ° C |
| Resolution | 9 to 12 bits (selectable) |
| Response time |
One of the biggest advantages of DS18B20 is that multiple DS18B20s can coexist on the same 1 wire bus. As each DS18B20 has a unique 64-bit serial code engraved at the factory, it is easier to tell them apart from each other.
This feature can be a huge advantage when you want to control many DS18B20s spread over a large area.
| Black | GND is a ground pin. |
| Yellow | The DQ is a 1-wire data bus that must be connected to a digital pin on the microcontroller. |
| Red | The VDD pin provides power to the sensor which can be between 3,3 and 5 V. |
Here is a summary of the most relevant specifications of the DS18B20 digital temperature sensor:
- This meter communicates via one-wire bus communication Power supply range: 3,0 V to 5,5 V
- The operating temperature range: -55ºC to + 125ºC Accuracy +/- 0,5 degrees celsius (between the measurement range -10ºC and 85ºC)
