DS18B20 Waterproof Digital Thermal Probe 1m

The DS18B20 Waterproof Digital Thermal Probe puts the well-known DS18B20 digital temperature sensor inside a sealed probe on a 1 m cable, so you can measure the temperature of water, soil, liquids and outdoor air. It sends readings as digital data over a single 1-Wire data line, which keeps wiring simple and makes it easy to use with Arduino, ESP32 and Raspberry Pi.

DS18B20 Waterproof Probe Specifications

• Sensor: DS18B20 digital temperature sensor
• Measuring range: -55 °C to +125 °C (sensor chip)
• Accuracy: ±0.5 °C from -10 °C to +85 °C
• Resolution: selectable 9 to 12 bits (0.0625 °C at 12 bits)
• Supply voltage: 3.0 V to 5.5 V
• Interface: 1-Wire, with a unique 64-bit address so several probes can share one data pin
• Cable: 1 m, 3 wires (VCC, GND and data)

DS18B20 Waterproof Probe Applications

• Aquarium, pool and water tank temperature monitoring
• Soil and greenhouse temperature logging
• Fridge, freezer and cold room monitoring
• Home brewing and liquid heating control
• Weather stations and IoT projects with ESP32 or ESP8266

What's in the Box

• 1 × DS18B20 waterproof temperature probe with 1 m cable

Tip: Connect a 4.7 kΩ pull-up resistor between the data wire and VCC, and use the OneWire and DallasTemperature libraries in the Arduino IDE. The sensor chip reads up to +125 °C, but the cable may not be rated that high, so check it before using the probe in very hot liquids.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
