Understanding DS18B20U Temperature Sensor Accuracy Problems

The DS18B20U temperature sensor is a highly popular and widely used device in a variety of applications, from DIY electronics projects to industrial temperature monitoring systems. It’s known for its digital output, ease of use, and relatively low cost. However, like all sensors, the DS18B20U can encounter accuracy issues that can undermine the precision of temperature readings. These problems can arise from several factors, including sensor limitations, environmental influences, and even wiring mistakes. In this first part, we’ll explore the common reasons behind these accuracy problems and identify potential pitfalls that can lead to unreliable sensor data.
