# How to increase Sensitivity and precision of a measuring sensor?

Considering the definition that

Sensitivity: Relation between the maximum of range, the sensor can $$\frac{i}{p}$$ to the corresponding $$\frac{o}{p}$$ given by the sensor due to it.
Ex: A pressure sensor can take a max of $$100\space PSI$$ and the corresponding $$\frac{o}{p}$$ it gives is $$5\space V$$. Then Sensitivity is $$\frac{5}{100} \space V/PSI$$.

Precision: A definition to quantify repeatability of value of the measurement when measured again and again in the same conditions. Noise reduces the precision of the measurement.

Is it safe to say that:
1) Amplifiers will increase the sensitivity of a sensor.
2) Noise filters will increase the precision of a sensor.

• What are your notations i/p and o/p? – Ben Crowell Jul 19 at 17:46
• Input and Output. – Chetan Waghela Jul 20 at 9:31
• Was it really easier & clearer to type $\frac{i}{p}$ as opposed to input? Is that notation common in electric circuits? – Kyle Kanos Jul 24 at 12:20
• It was corrected by community. I think the question should be downvoted to -50 because of all the formatting errors. It is really really hard to understand what i/p stands for (sarcasm). Thank you have a nice day. – Chetan Waghela Jul 25 at 7:13
