Using the 1-Wire protocol, multiple sensors can be connected to a single microcontroller pin, simplifying wiring and reducing hardware complexity.

This sensor is perfect for IoT devices, smart home monitoring, environmental sensing, aquariums, water tanks, and industrial temperature measurement. It comes in several variants: bare sensor (TO-92 package), with waterproof probe, and with protective stainless steel casing for harsh environments.

It supports both parasitic power mode and external power mode, giving flexibility for different applications.

Key Features:

  • Temperature Range: -55°C to +125°C (-67°F to +257°F)

  • Accuracy: ±0.5°C from -10°C to +85°C

  • Communication: 1-Wire interface

  • Multiple sensors can share a single microcontroller pin

  • Waterproof / Stainless steel probe options available

  • Power Supply: 3.0V – 5.5V DC

  • Operating Current: 750µA (active), 1µA (standby)

  • Packaging Options: TO-92 / Waterproof probe / Protective stainless steel case
