What Can We Learn About LDR Sensitivity From Strobe Light Experiments?

[crazycaddy]

Ive gone about doing an experiment without thinking about what I'm actually trying to find out (result of poor planning) and I am now in a bit of a pickle.
My experiment involved an LDR in a circuit connected to a digital oscilloscope (picoscope).
I placed a stroboscope 100cm away and set the frequency from 10Hz to 100Hz and regular intervals of 10Hz, I repeated it 5 times for each frequency and took an average. I then moved the stroboscope 25cm closer and repeated.

Now what I need to know is what useful information could I find about the sensor (LDR) from these results.

Don't hesitate to ask any questions about my 'experiment'.

From your experiment, you can determine the frequency response of the LDR. This will tell you how quickly the LDR responds to changes in light intensity and how much it changes in response to those changes. You can also measure the sensitivity of the LDR by looking at how much the output changes with changes in light intensity. Additionally, you can measure the dynamic range of the LDR - that is, the range from the lowest level of light intensity it can detect to the highest level of light intensity it can detect.

First of all, it's important to acknowledge that it's completely normal to encounter challenges and unexpected outcomes in scientific experiments. The key is to learn from these experiences and improve your experimental design for future studies.

Based on the information provided, it seems like you are trying to investigate the relationship between the distance of the stroboscope and the readings of the LDR. By varying the distance and frequency of the stroboscope, you can observe how the LDR responds to different levels of light intensity.

One possible useful information you could gather from your results is the sensitivity of the LDR. By analyzing the average readings at each frequency and distance, you can determine the range of light intensity that the LDR is able to detect and respond to. This can provide insight into the capabilities of the sensor and its potential applications.

Additionally, you could also compare the readings from different distances to see if there is a noticeable difference in the LDR's response. This could indicate the sensor's sensitivity to changes in light intensity and how it may be affected by distance.

In the future, it may be helpful to have a specific hypothesis or research question in mind before conducting the experiment, as this can guide your experimental design and help you focus on gathering relevant data. It's also important to carefully plan and control all variables in the experiment to ensure accurate and reliable results.

Overall, even though your experiment may not have gone as planned, there is still valuable information that can be gained from your results. Keep in mind the lessons learned and use them to improve your future experiments.
