How can you design a circuit for a simple electronic thermometer using an LM35 sensor?
To design a circuit for a simple electronic thermometer using an LM35 temperature sensor, connect the LM35 to a microcontroller's analog input. The LM35 provides an analog voltage proportional to temperature. The microcontroller converts this voltage to a temperature reading, which can be displayed on an LCD or LED display. Include a power supply circuit for the sensor and the display.
