Key Features of DS18B20 Waterproof Digital Thermometer Sensor Probe

Truly Waterproof: Sealed stainless-steel probe rated IP68-safe for full submersion in water, soil, or chemical tanks.
High Precision: +/-0.5 degreesC accuracy with 12-bit resolution gives you laboratory-grade readings without expensive equipment.
Simple 1-Wire Interface: Only one GPIO pin (plus a 4.7 kOhm pull-up resistor) needed; chain dozens of sensors on a single bus using unique ROM addresses.
Wide Voltage Range: Runs on 3.3 V or 5 V logic, compatible with virtually every popular microcontroller platform.
Parasitic Power Mode: Can operate with just two wires (data + GND), simplifying long cable runs.
Digital output-no ADC or analog calibration required
Each sensor has a unique 64-bit serial code for multi-sensor networks
Programmable alarm/threshold registers stored in on-chip EEPROM
Stainless-steel probe resists corrosion in water, soil, and mild chemicals
PVC-jacketed cable withstands bending and moderate abrasion
Ready-to-use Arduino libraries (DallasTemperature, OneWire) and MicroPython drivers

Perfect For

Aquarium & Fish Tank Monitor: Submerge the probe to continuously track water temperature and trigger heater/cooler relays automatically.
Hydroponics & Smart Agriculture: Monitor nutrient solution or soil temperature to optimize plant growth conditions.
Home Weather Station: Combine with a DHT22 humidity sensor and BMP

How to Connect (Typical Arduino Wiring)

Red Wire (VCC)	-> 5 V (or 3.3 V)
Black Wire (GND)	-> GND
Yellow/White Wire (Data)	-> Digital Pin (e.g., D2) with a 4.7 kOhm pull-up resistor to VCC

Install the OneWire and DallasTemperature libraries in the Arduino IDE, upload the example sketch, and you'll see temperature readings on the Serial Monitor within seconds.
