Customer Questions & Answers
What measurement accuracy and tolerance does the DS18B20 sensor offer within its operating range?
The DS18B20 sensor offers a typical accuracy of ±0.5°C in the range from -10°C to +85°C. Outside that range, the tolerance may gradually increase to approximately ±2°C at the extremes (-55°C or +125°C).
Is the included 1-metre cable suitable for outdoor installations or damp environments?
The cable and sensor capsule are designed to be water-resistant, making them suitable for use in damp environments and outdoors, although it is recommended to check the sealing of the electrical connections to prevent ingress in long-term outdoor installations.
What are the recommendations for maintaining the sensor’s accuracy over time?
To maintain accuracy, it is important to avoid the build-up of dirt or corrosion on the probe and not expose it to rapid thermal shocks or aggressive chemicals; it is recommended to inspect and clean it every 6–12 months depending on the environment.
What technical differences does it offer compared with other temperature sensors such as the DHT22?
The DS18B20 provides greater accuracy and a wider operating range (-55°C to +125°C), measures temperature only (not humidity), and allows multiple sensors to be connected on a single 1-Wire bus, unlike the DHT22 which also measures humidity but has a narrower range and lower accuracy.
Which devices is the Sonoff DS18B20 sensor compatible with?
The Sonoff DS18B20 sensor is compatible with most microcontrollers and home automation systems that support digital temperature sensors, operating with voltages between 3.0 and 5.5V.
How do you install the Sonoff DS18B20 temperature sensor?
The sensor is easy to install thanks to its 1 metre cable and waterproof design. It connects to compatible devices with a 3.0 to 5.5V power supply to start measuring temperature.
What temperature range does the Sonoff DS18B20 sensor measure?
The sensor measures temperatures from -55°C to +125°C, ideal for a wide variety of applications.
Is the Sonoff DS18B20 sensor waterproof?
Yes, the sensor is designed to be waterproof, making it suitable for damp or exposed environments.
What is the weight and cable length of the sensor?
The sensor weighs 26 grams and has a 1 metre cable length to make installation easier.
