3M DS18b20 temperature probe

1-Wire Digital Communication Protocol: Transmits high-accuracy temperature data across a single signal wire, requiring only one microcontroller I/O pin for multi-sensor array deployments.

Waterproof Stainless Steel Capsule: Sealed inside a corrosion-resistant stainless steel tube (6 x 50 mm) to enable safe, long-term liquid immersion monitoring.

Extended 3-Meter Heavy-Duty Cable: Factory-fitted with an extra-long 3-meter flexible connection cable for long-reach applications across large tanks, HVAC ducts, and greenhouse beds.

Broad Operating Temperature Range: Accurately measures across a wide thermal spectrum from -55°C to +125°C with user-configurable 9-to-12 bit digital resolution.

Multi-Platform Microcontroller Support: Seamlessly integrates with Arduino, Raspberry Pi, ESP8266, ESP32, and STM32 platforms via standard 1-Wire library modules.

Probe Sheath Material: High-grade, corrosion-resistant stainless steel capsule with sealed strain-relief tubing and insulated lead wiring.

Technical Specifications:

Sensor Chip: Dallas/Maxim DS18B20 digital temperature sensor.

Operating Voltage: 3.0V – 5.5V DC.

Temperature Range: -55°C – +125°C (-+ 0.5°C accuracy from -10°C to +85°C).

Cable Length: 3 Meters.

Color: Silver Stainless Steel Capsule with Black Cable.

Usage Advice: Requires a 4.7 kΩ pull-up resistor connected between VCC and DATA lines for stable signal transmission over 3-meter cable runs; check lead color assignment (Red: VCC, Black: GND, Yellow/Green: DATA) before powering on.

Maintenance: Keep the cable-to-probe junction clean and inspect lead insulation periodically when operating in high-humidity or corrosive environments.

Essential Long-Reach Submersible Probe: Position as the ultimate extended-length waterproof thermal sensor for large aquariums, home brewing fermentation vats, outdoor weather stations, and multi-tier hydroponics.

Highlight Extended 3-Meter Reach: Emphasize how the built-in 3-meter cable eliminates the need for messy hand-soldered wire extensions or custom cable splicing.

Recommended Cross-Sell Add-ons: Pair with DS18B20 Adapter Module for Arduino, 1M DS18b20 temperature probe, PT100 Platinum Resister Temp Sensor Probe -20℃~450, and ESD antistatic mat 50x40CM PCB Welding Mat.
