  Temperature Sensor

• The Temperature Sensor is a project developed using an Arduino UNO. It includes a TMP36 temperature sensor, an LCD display, a piezo speaker, an LED, and a potentiometer. The sensor continuously measures the temperature, and the readings are displayed on the LCD screen. If the temperature reaches or exceeds 25 °C, the piezo speaker emits a beep and the red LED lights up as a warning. To improve accuracy, the board takes 10 temperature readings every 20 milliseconds and then calculates the root mean square (RMS) value to obtain a more stable and precise result.
