DS18B20 in DS18B20 1-Wire Temperature Family
The DS18B20 family, primarily manufactured by Maxim Integrated (now part of Analog Devices), is a series of digital thermometers providing 9-bit to 12-bit Celsius temperature measurements. Communicating over a 1-Wire bus, these sensors require only one data line and a ground for communication with a central microprocessor. They are widely recognized for their ability to derive power directly from the data line via 'parasite power,' eliminating the need for an external power supply in many remote sensing applications.

Variants within the DS18B20 family differ primarily in packaging and power configurations. The standard DS18B20+ uses the TO-92 package for through-hole mounting, while the DS18B20-PAR is specifically optimized for parasite-power mode by internalizing the connection between VDD and GND. Engineers should also note differences in tape-and-reel options and lead-free compliance, as indicated by suffixes like T&R or the plus sign for RoHS compliance.
