The project using the Love-o-Meter code with the Arduino is a great way to dig into temperature sensing and digital signal processing. The code demonstrates how to use a TMP36 temperature sensor, along with red LEDs and resistors, to create a visual indicator of temperature changes.
Adjusting the baseline temperature from 20°C to 22°C in your Arduino project will affect the sensitivity of the temperature readings and the corresponding LED indicators. Here's how the change might impact the system:
New Baseline Temperature: By setting the baselineTemp constant to 22.0°C instead of 20.0°C, you are shifting the reference point for your temperature measurements. This means that the LEDs will now react to a higher starting temperature.
Increased Sensitivity: With a higher baseline temperature, the system becomes more sensitive to smaller increases in ambient temperature. For example, previously, an ambient temperature of 22°C would not have triggered any LEDs, but now, it would light up the first LED.
Potential Applications: This adjustment could be particularly useful in environments where monitoring slight temperature changes is crucial, such as in sensitive laboratory settings or in areas where equipment might be sensitive to minor temperature fluctuations.
while changing the baseline temperature increases the system's sensitivity to higher temperatures, it also means that the LEDs will be less responsive to temperatures below this new baseline.
