Temper sensor ds18b20 1m
🌡️ Waterproof DS18B20 Temperature Sensor – 1 m Probe
Overview
The DS18B20 waterproof probe is a stainless-steel digital temperature sensor with a 1 m cable. It uses the 1‑Wire protocol, enabling accurate temperature readings from –55 °C to +125 °C with ±0.5 °C accuracy. Perfect for outdoor, liquid, or long-distance applications.
Key Features
- Waterproof stainless-steel probe, 6 mm diameter
- Uses 1‑Wire interface – single data line + ground
- 9–12 bit configurable resolution, default 12‑bit
- Measures temperature from –55 °C to +125 °C (±0.5 °C from –10 to +85 °C)
- Pre-wired with 1 m cable and pull-up resistor included
- Power supply: 3.0–5.5 V
- Each sensor has a unique 64‑bit serial code – supports multiple sensors on one data line
Wiring with Arduino UNO
| Probe Wire | Connect To |
|---|---|
| Red | VCC (3.3 V or 5 V) |
| Black | GND |
| White/Yellow (DQ) | Digital pin (e.g., D2), with 4.7 kΩ pull-up to VCC |
📌 Ensure common ground between Arduino & sensor.
