How do different sensors compare in terms of accuracy?

The accuracy of sensors can vary significantly based on their type and application. For example, temperature sensors like thermocouples are generally accurate within a few degrees, while laser rangefinders can achieve millimeter-level precision. What specific sensors are you interested in comparing?

I'm curious about temperature sensors and pressure sensors.

Temperature sensors, such as thermistors and RTDs, typically have an accuracy of ±0.1°C to ±1°C. Pressure sensors, on the other hand, can vary widely; some can be accurate to within ±0.5% of full scale. Are you looking for specific models or applications?

Yes, I'm looking at thermocouples and piezoresistive pressure sensors.

Thermocouples can have an accuracy of around ±1°C, depending on the type, while piezoresistive pressure sensors can achieve accuracies of ±0.1% to ±0.5% of full scale. It really depends on the specific application and environment. Do you need help with selecting the right sensor for a project?

That would be great! I'm working on a weather station.

For a weather station, a combination of a thermocouple for temperature and a piezoresistive sensor for pressure would work well. Make sure to consider the environmental conditions and the required accuracy for your measurements.
