This project has been the study of an house indoor and outdoor temperatures. In particular the original goal was to make a tool with simple installation and low maintenance.
This project has been the creation of a receiver in conjunction with a certain numbers of transmitter using radio frequency at 433 MHz. Thanks to this inexpensive solution, both in terms of power and money, now I have a system that give me the possibility of collecting temperature but also every physical quantity I would detect: voltage, humidity, open doors, etc.
The transmitter is made of the following components:
- ATMEGA328P-PU with Arduino bootloader
- Crystal 16MHz
- 2 22 pF ceramic capacitors
- RF433 Tx module (you can buy all 4 components in kit)
- 1 battery holder for 3 batteries
