Dew Point Calculator — Arduino DHT11 Sensor Prototype

Dew Point Calculator was an early Arduino sensor project from 2018. The project used a DHT11 sensor to read temperature and humidity, then calculated dew point using a formula and displayed the result on an LCD. This project is useful in the Early Work archive because it shows Parth experimenting not only with hardware input/output, but also with sensor data and mathematical calculation. This project shows a different type of early learning: combining electronics with data interpretation. It adds variety to Parth's early work because it connects sensors, formulas, unit conversion, and display output.

The project explored how environmental readings such as temperature and humidity could be converted into a more useful calculated value: dew point.

The Arduino sketch reads humidity and temperature from a DHT11 sensor, checks whether the sensor reading is valid, calculates dew point, converts the dew point value from Celsius to Fahrenheit, and prints the result on an LCD.

Parth wrote the Arduino logic for reading sensor values, checking sensor errors, applying the dew point calculation, converting units, and displaying the result.
