Designing a Simple Temperature Data Logger

Necessary Components

- ATMEGA48-20AUR Microcontroller

- LM35 Temperature Sensor

- 16x2 LCD Display

- 10K Ohm Potentiometer

- Breadboard and Jump Wires

Circuit Connections

1. Power Connection

- VCC (Pin 7) and AVCC (Pin 20): Connect these to a stable voltage source, ranging from 1.8V to 5.5V.

- GND (Pins 8 and 22): Connect to circuit ground.

2. Temperature Sensor Interface

- Pin 23 (ADC0): Attach this pin to the output of LM35.

3. LCD Display

- Pin 12 (PB4) to Pin 19 (PB7): Connect these pins to the data pins (D4 to D7) of the LCD.

- Pin 28 (PC5): Connect to the RS pin on the LCD.

- Pin 27 (PC4): Connect to the Enable (E) pin on the LCD.

4. Potentiometer

- Pin 5 (PC2): Connect to the middle terminal of a 10K Ohm potentiometer for LCD contrast control.

Design Considerations

1. Voltage Consistency: The ATMEGA48-20AUR operates from 1.8V to 5.5V. The power supply needs to be consistent.

2. Sensor Accuracy: For precise temperature readings, proper placement and orientation of the LM35 sensor are crucial.

3. LCD Power Requirements: Ensure the LCD and ATMEGA48-20AUR are compatible in terms of voltage and current ratings.

4. Programming Space: Given the limited 4 KB of Flash memory in the ATMEGA48-20AUR, code should be optimized for space.

5. Protection: Consider including overvoltage and reverse polarity protection in your design.

In summary, the ATMEGA48-20AUR offers a versatile set of features that make it well-suited for applications like temperature data logging. However, when designing circuits with this chip, factors like voltage stability, sensor placement, and code efficiency are critical considerations.
