How many inches of concrete should cover the temperature sensor?

2 inches
3 inches
4 inches
5 inches

The correct answer is: 3 inches

The recommended coverage for a temperature sensor embedded in concrete is typically around 3 inches. This amount of concrete ensures that the sensor can accurately measure the temperature of the surrounding concrete while providing appropriate insulation to avoid interference from the external environment. A coverage of 3 inches also helps in minimizing the potential impact of variations in outdoor temperatures or drafts that could skew temperature readings, which is crucial for achieving optimal curing conditions and ensuring the integrity of the concrete mixture. Proper installation and coverage are essential for obtaining consistent data, and this depth is well established in industry standards and best practices for concrete placement.
