DS18B20 Digital Temperature Sensor

1-Wire Digital Communication: Transmits digital temperature data over a single signal line (plus ground), significantly reducing micro-controller I/O pin requirements.

Programmable Resolution Settings: Supports configurable 9-bit to 12-bit digital temperature conversion, giving users flexible control over precision versus conversion speed.

Wide Operational Sensing Spectrum: Accurately measures temperatures across a broad spectrum from -55°C to +125°C with -+ 0.5°C accuracy in the -10°C to +85°C range.

Unique 64-Bit On-Chip Address: Every IC features a factory-lasered 64-bit ROM ID, allowing multiple DS18B20 sensors to coexist on a single 1-Wire bus for multi-point thermal tracking.

Parasitic Power Option: Capable of deriving operating power directly from the data line, eliminating the need for a dedicated local power line in remote sensing nodes.

Housing Material: Standard molded plastic TO-92 through-hole package with three solid tin-plated copper leads.

Technical Specifications:

Sensor Chip: Maxim / Dallas DS18B20 Programmable Digital Thermometer IC.

Operating Supply Voltage: 3.0V – 5.5V DC.

Temperature Measurement Range: -55°C – +125°C (-+ 0.5°C accuracy between -10°C and +85°C).

Conversion Time: 750 ms (max) at 12-bit resolution.

Data Protocol: Dallas 1-Wire Serial Interface.

Package Type: TO-92 (3-Pin Through-Hole).

Enclosure Color: Black Molded Epoxy with Silver Pins.

Usage Advice: Place a standard 4.7 k}\Omega$ pull-up resistor between the VDD (Power) and DQ (Data) lines; use standard OneWire and DallasTemperature libraries in Arduino IDE or ESPHome.

Maintenance: Keep the through-hole pins dry and free from oxidation; avoid direct immersion in liquids without protective waterproof thermal tubing or encapsulation.

Essential Industry-Standard Digital Temperature IC: Position as the ultimate, highly versatile 1-Wire digital temperature sensor for DIY weather stations, smart home nodes, food storage monitors, and multi-point climate loggers.

Highlight Multi-Drop 1-Wire Capability: Emphasize how multiple sensors can be wired to a single digital pin, drastically simplifying wiring complexity for multi-zone monitoring networks.

Recommended Cross-Sell Add-ons: Pair with DS18B20 Temperature Sensor Module, TMP36 Temperature Sensor, LM35DZ PrecisionTemperature Sensor IC, and ESD antistatic mat 50x40CM PCB Welding Mat.
