Why Choose This DS18B20 Waterproof 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.
- 100% Authentic Chip: Genuine Maxim/Analog Devices DS18B20 sourced from trusted, authorized distributors-authentication verified.
- Fast Shipping: 1-5 day shipping, 7-8 day delivery across India from our Bengaluru warehouse; same-day dispatch available in Bengaluru.
- Expert Support Included: Full technical guidance via email and WhatsApp to help you wire, code, and troubleshoot.
Key Features at a Glance
- 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
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.
Project Ideas
- 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
