AVT961 A

Home, extended, electronic weather station. The device allows you to measure and visualize in digital form basic weather parameters; temperature, humidity and atmospheric pressure. The work of all sensors as well as the display and buttons is controlled by the PIC18F2680 microcontroller. It has in its structure all the necessary peripheral systems as well as program and RAM memory.
All information is displayed on the graphic display - a popular module from a Nokia mobile phone has been used. The outdoor temperature measurement module has an additional microcontroller. It allows for its easy extension with new functions. Communication between the module and the central unit is carried out in the RS232 standard.

The device is especially recommended for all weather-resistant people and those who want to keep track of changes in the aura on a regular basis
