DS18S20Z+T&R datasheet by Maxim Integrated Products

DS18S20Z+T&R Frequently Asked Questions (FAQs)

• What is the accuracy of the DS18S20Z+T&R temperature sensor?
  The DS18S20Z+T&R has an accuracy of ±0.5°C from -10°C to +85°C, and ±1°C from -40°C to +125°C.
• How do I connect multiple DS18S20Z+T&R sensors to a single bus?
  You can connect multiple DS18S20Z+T&R sensors to a single bus by connecting the VDD, GND, and DQ pins of each sensor to the corresponding pins of the microcontroller, and using a unique ROM code for each sensor.
• What is the maximum cable length for the DS18S20Z+T&R sensor?
  The maximum cable length for the DS18S20Z+T&R sensor is 100 meters, but it's recommended to keep the cable length as short as possible to minimize signal degradation.
• How do I convert the temperature data from the DS18S20Z+T&R sensor to Celsius or Fahrenheit?
  The DS18S20Z+T&R sensor returns temperature data in a 16-bit signed integer format, where 1 LSB = 0.0625°C. You can convert the data to Celsius by multiplying the integer value by 0.0625, and to Fahrenheit by multiplying the Celsius value by 1.8 and adding 32.
• What is the power consumption of the DS18S20Z+T&R sensor?
  The DS18S20Z+T&R sensor has a typical active supply current of 1.5mA and a standby current of 0.5µA.
