DS18S20+ Frequently Asked Questions (FAQs)

  • The maximum cable length for the 1-Wire bus is 100 meters (330 feet), but it's recommended to keep it as short as possible to minimize signal degradation and noise.
  • Each DS18S20+ has a unique 64-bit ROM code that can be used to identify and address individual sensors on the same bus. You can use the ROM code to select and communicate with specific sensors.
  • The DS18S20+ has an accuracy of ±0.5°C from -10°C to +85°C, and ±1°C from -40°C to +125°C. However, this accuracy can be affected by factors such as sensor calibration, noise, and thermal gradients.
  • The DS18S20+ outputs temperature data in a 16-bit signed integer format, where 1 LSB (least significant bit) equals 0.0625°C. You can convert this data to Celsius or Fahrenheit using a simple scaling formula.
  • The DS18S20+ has a typical active current of 1.5 mA and a standby current of 0.5 µA. The power consumption can be minimized by using the parasite power mode, which allows the sensor to draw power from the 1-Wire bus.
