摘要

电阻-时间转换器由电压跟随器、桥式放大器和施密特触发器组成，以增加像Arduino这样的嵌入式系统的电阻灵敏度和电阻范围。Arduino的Analog input Read scale在0 ~ 1024之间，最大输入电压读数为5V，这限制了Arduino的电阻传感能力，影响了其精度。因此，采用R to t变换器来提高其电阻感知能力。并给出了实验值来证明上述结论。

A Resistance-to-time Convertor to enhance Resistive Sensitivity of Embedded Systems

A Resistance-to-time convertor consists of a voltage follower, a bridge amplifier and Schmitt trigger to increase the resistive sensitivity and resistance range of an embedded system like Arduino. Arduino has an Analog input Read scale between 0 to 1024 and max input voltage reading of 5V, due to which its resistance sensing capability is restricted and the accuracy is hindered. Therefore, the R to t convertor is used to improve its resistance sensing capability. Experimental values are also given to demonstrate the above.
