Dražice Boiler DS18B20 Sensor Holder

This 3D-printable holder is designed for anyone who wants to monitor their Dražice boiler's water temperature using a DS18B20 temperature sensor and a system like Home Assistant.

Placing a sensor directly on the boiler's outer shell can give you an inaccurate reading, as the sensor may not be in proper contact with the inner tank. This simple, effective holder solves that problem by ensuring the sensor maintains firm and consistent pressure against the boiler's inner wall.

Key Features

• Optimal Contact: The design is curved to perfectly match the boiler's surface, ensuring maximum contact between the sensor and the boiler's inner wall for an accurate temperature reading.
• Cable Management: It not only holds the sensor but also guides the cable cleanly away from the boiler, preventing kinks and ensuring a tidy installation.
• Perfect Fit: Specifically designed for Dražice boilers, this model provides a secure fit for your DS18B20 sensor.
• Easy Integration: By using these holders with a few DS18B20 sensors placed at different heights on the boiler (e.g., top, middle, and bottom), you can get a comprehensive picture of your water temperature stratification. This data is invaluable for optimizing your water heating schedule and saving energy.

How to Use

1. Print the holder using your favorite filament. PETG or ABS are good choices due to their heat resistance, but PLA will also work just fine.
2. Insert your DS18B20 sensor into the holder's slot.
3. Place the holder on the boiler's surface, positioning the sensor as desired.
4. Secure the holder in place. A strong adhesive or a simple tie-down strap can be used.

This small print is an essential tool for any smart home enthusiast looking to take control of their boiler and gather precise data for a more efficient and smarter heating system.
