ATtiny13 – temperature logger using LM35 and Software UART

This project is about a simple temperature logging system using ATtiny13 and the Software UART. The system reads the temperature every second and shows it on the serial console (baudrate 19200, settings 8N1). The temperature is shown in °Celsius. LM35 has been used as the temperature sensor. Complete example code is on GitHub. LM35 Temperature Sensor … Read more
