Convert voltage to acceleration

In summary, the conversation discusses converting voltage to acceleration from an accelerometer and how to use the sensitivity of the accelerometer to do so. The conversion can be done by dividing the voltage by the sensitivity, and units can be treated as variables in the calculation. The conversation also mentions the possibility of finding sources in an instrumentation book or using basic algebra to prove the conversion.

Look at the units you're starting with and what the units are for the conversion constant ("sensitivity"). Do you want to multiply or divide to get the units you're looking for?

can voltage divide sensitivity of accelerometer to get acceleration result ?

v / mv/g = g

hi manutdkaki :smile:
manutdkaki said:
v / mv/g = g

that's right …

the beauty of units is that they multiply and divide exactly like ordinary fractions :smile:

v / (mv/g) = vg/mv = g/m = kg :wink:

v/(mv/g)

v is voltage
mv = milivoltage
g= acceleration

got any book source to prove it ?
thanks

Units are treated as variables. So you can prove it with elementary algebra. I guess you need a book on algebra.
 

FAQ: Convert voltage to acceleration

1. How do you convert voltage to acceleration?

To convert voltage to acceleration, you will need to use an accelerometer. The accelerometer measures the change in voltage caused by the acceleration of an object. By using the formula a = V/g where a is the acceleration, V is the voltage, and g is the acceleration due to gravity, you can convert the voltage reading to acceleration.

2. What is the relationship between voltage and acceleration?

The relationship between voltage and acceleration is that acceleration causes a change in voltage. When an object is accelerated, the accelerometer senses this change in voltage and measures it. The higher the acceleration, the greater the change in voltage will be.

3. Can any type of voltage be converted to acceleration?

No, only certain types of voltage can be converted to acceleration. Specifically, only voltage that is caused by the acceleration of an object can be converted. Other types of voltage, such as static voltage, cannot be converted to acceleration.

4. Are there any limitations to converting voltage to acceleration?

Yes, there are limitations to converting voltage to acceleration. The accuracy of the conversion depends on the sensitivity and range of the accelerometer being used. Additionally, external factors such as temperature and electromagnetic interference can affect the accuracy of the conversion.

5. How is voltage to acceleration conversion used in scientific research?

Voltage to acceleration conversion is used in various scientific research studies, particularly in the fields of physics and engineering. It is commonly used in experiments that involve measuring and analyzing the movement and acceleration of objects. This data can then be used to understand and improve various systems and technologies.
