AVT2852 B

A set that allows you to create an unusual window thermometer. Its originality is based on the method of displaying information about the current temperature. LED diodes are used for this purpose, not in a traditional ruler, but in a spiral. In addition, colors were chosen so that positive temperatures would be represented by warm colors, while negative ones - cold ones.
The device is designed for readings in the range of -30 to +50 ° C. The readout field is constructed in such a way that at positive temperatures diodes from 0 up light up and negative ones from zero down.

The device is especially recommended as home furnishings; everyone interested in long walks

Selected parameters:

• temperature measurement in the range -30 to +50 ° C
• 1stC accuracy
• reading field - 81 items of differently colored LED diodes
• diode control - matrix
• built-in voltage stabilizer
• 10-12 Vac power supply
• in the set there is a printed circuit board, programmed layout, set of elements and documentation
