Waterproof & Durable Probe: Encased in waterproof, corrosion-resistant, rustproof with highly thermally conductive sealant. Perfect for continuous submersion, wet environments, and harsh conditions. High Accuracy & Wide Temperature Range: Delivers precise temperature readings from -55°C to +125°C (-67°F to +257°F) with an accuracy of ±0.5°C. Ideal for demanding applications. Simple Wiring & Quick Integration: Features clearly separated red (VCC), yellow (Data), and black (GND) wires with heat shrink tubing. Easily connects to popular platforms like for Arduino, for Raspberry Pi, for ESP32, and for STM. Low Power & Flexible Voltage Operation: Efficiently operates on a wide voltage range of 3.0V to 5.5V, ensuring compatibility with various microcontrollers and development boards without complex power regulation. Reliable 1-Wire Interface & Tip: Utilizes the robust for Dallas 1-Wire protocol for simplified communication. For optimal stability, use a 4.7K resistor between Data (Yellow) and VCC (Red). SURFACE TREATMENT: Stainless Steel Seal RESOLUTION: 9~12 Bits Adjustable TEMPERATURE RANGE: -55°C to +125°C HIGH ACCURACY: ±0.5°C OPERATING VOLTAGE: 3V - 5.5V LENGTH:1m WIRING: Red (VCC), Yellow(DATA), Black (GND), Separated by Heat Shrink Tubing Using a 4.7K resistor between the Data and VCC will make the testing easier.
