consider models adapted for the application of these sensors in different fields. 

Extended Mathematical Models 

1. Accuracy Model:

world applications, sensors can be affected by various conditions (e.g., temperature, humidity). 

To account for these factors, the accuracy model can be extended as follows:

𝐴 = 1
⎸𝑥measured(𝑝1,𝑝2,….𝑝𝑛)−𝑥𝑡𝑟𝑢𝑒  ⎸

𝑥𝑡𝑟𝑢𝑒
 

Here, (𝑝1, 𝑝2, … . 𝑝𝑛) represent various external factors (e.g., temperature, humidity) and 𝑥𝑡𝑟𝑢𝑒 is 

the value measured under the influence of these factors. 

2. Sensitivity Model: 

Understanding the sensitivity of a sensor, that is, how it responds to small changes, is crucial. 

This helps determine how the sensor performs under various conditions: 

𝑠 =
𝜕𝑦

𝜕𝑥
(𝑥, 𝑝1, 𝑝2, … . 𝑝𝑛) 

 Here, 
𝜕𝑦

𝜕𝑥
 represents the change in the sensor's output relative to the input signal  x  and other 

external factors 𝑝1, 𝑝2, … . 𝑝𝑛. 

 

3. Reliability Model: 

   To evaluate reliability, it is essential to study the variability in the sensor's output. The 

following equation can be used to analyze how this variability changes under different 

conditions: 

𝑅 = 1 −
√𝐸⦋(𝑌 − 𝜇)2⦌

𝜇
 

Here, √𝐸⦋(𝑌 − 𝜇)2⦌ represents the variance in the sensor output values, and 𝜇 is the mean value. 

This model allows for determining the sensor's reliability under various conditions. 

These models are essential tools for gaining a deeper understanding of how sensors perform in 

various fields such as medical diagnostics, automotive engineering, and environmental
