Send the measurements of one or more DS1820/DS18S20/DS18B20 1-wire thermometers over 433 MHz radio using an AVR microcontroller.
Components:
- AVR microcontroller
- DS18* 1-wire thermometer
- XKFST radio transmitter
- an LED
The code uses 3 I/O pins for:
- communicating with the thermometers
- sending the data through the radio
- driving a status LED
The final size is about 1700 bytes.
The project is using previous works of others, so thank you for:
