Supplied with ≈1 m PVC\/PTFE-sheathed lead (cable is not fully waterproof or flame-retardant); cable maximum continuous temperature ≈85 °C. For long-term submersion or humid use, seal the cable joint with heat-shrink, silicone, or epoxy.\u003c\/li\u003e\n\u003cli\u003eTemperature specs: Range −55 °C to +125 °C (−67 °F to +257 °F); typical accuracy ±0.5 °C from −10 °C to +85 °C. Resolution selectable 9\/10\/11\/12 bits (12-bit LSB = 0.0625 °C); conversion time up to ~750 ms at 12-bit (9≈94 ms, 10≈188 ms, 11≈375 ms). Supports user-programmable non-volatile upper\/lower alarms (TH\/TL) and alarm-search. Operates on a 3.0–5.5 V supply and supports both external-power and parasitic-power modes (external VDD recommended for stable long-distance or multi-sensor installations).\u003c\/li\u003e\n\u003cli\u003ePackage \u0026amp; wiring colors: Includes sensor model DS18B20 ×4, plugable terminal adapters (e.g., model DFR0055) ×4, and 1m sensor cables (e.g., model FIT0011) ×4. Sensor leads: green = DATA, red = VCC, yellow = GND. Adapters may be wired in two variants—check before wiring: Type A: red=VCC, black=GND, yellow=DATA; Type B: red=VCC, yellow=GND, green=DATA. Verify mappings or test with a multimeter before powering.\u003c\/li\u003e\n\u003cli\u003e1-Wire bus notes: Uses the 1-Wire digital bus; each sensor has a unique 64-bit ROM ID for multi-point management. Use a 4.7 kΩ pull-up from DATA to VCC; for long runs use shielded cable, proper grounding and waterproofed joints. Parasitic power is supported, but for critical or long-distance installations use separate VDD for stability.\u003c\/li\u003e\n\u003cli\u003eQuick installation: Insert each probe into a plugable terminal adapter (e.g., DFR0055) and connect to a host device (microcontrollers or single-board computers). Wire VCC (3.0–5.5 V) → GND → DATA (1-Wire) with a 4.7 kΩ pull-up on DATA, and use standard 1-Wire libraries (for example, the DallasTemperature library) to read values. Calibrate with a short water bath or known temperature before deployment and seal all connections.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Brand: Fasvicna","offers":[{"title":"Default Title","offer_id":52033107034400,"sku":"B0FMR9YXMM","price":16.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1006\/7682\/9472\/files\/51UDnhjQzoL.jpg?v=1784932446","url":"https:\/\/tinyracer.com\/products\/4-pack-ds18b20-waterproof-temperature-sensor-probe-stainless-steel-digital-sensor-with-adapter-cable-compatible-with-arduino-raspberry-pi-esp32","provider":"TinyRacer","version":"1.0","type":"link"}
