About this item

  • Premium materials: Stainless-steel probe with waterproof seal, approx. 6–7 mm Ø and 26–45 mm length, corrosion-resistant to reduce short-circuit risk. 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.
  • Temperature 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).
  • Package & 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.
  • 1-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.
  • Quick 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.

    I found the replacement parts I needed for my RC truck without having to search through unrelated products. The categories were easy to understand, and the new wheels and suspension parts worked well for my weekend build.

    TinyRacer has a practical selection of RC tools, batteries, and upgrade parts. I picked up several items for maintaining my crawler, and everything made my workbench setup feel much more organized.

    Olivia Parker — Denver, Colorado

    I am still fairly new to RC cars, so I appreciated how clearly the products were grouped. It was easy to compare chargers, connectors, and maintenance supplies for my first off-road vehicle.

    I enjoy upgrading and adjusting my RC vehicles, and TinyRacer makes it convenient to browse parts for different projects. I especially liked the variety of tires, hardware, and drivetrain components available.
