Twoo DS18B20 Waterproof Temperature Sensor Probe: Waterproof stainless steel encapsulation
This DS18B20 waterproof temperature sensor is designed for DIY electronics enthusiasts and hobbyists who need reliable, precise monitoring in projects like home brewing, greenhouse control, or aquarium management. While many sensors focus on basic readings, this stainless steel probe offers peace of mind for hands-off monitoring, ensuring your sensitive setups stay within safe limits without constant manual checks.
Its unique 64-bit ID and programmable alarm system let you set specific upper and lower triggers, so you receive alerts before issues arise. The waterproof encapsulation handles humid environments, and the 1-meter cable provides flexibility for placement. With ±0.5°C accuracy from -10°C to +85°C and a 9 to 12-bit selectable resolution, it delivers detailed data for informed adjustments. Multiple sensors can share one pin, simplifying wiring for complex setups. Use it with 3.0V to 5.5V power, and rely on its digital signal that won't degrade over distance.
