AVT763 B

We present an unusual room thermometer. The temperature readout is shown by the color of the multicolor RGB LED. The color changes smoothly from blue (signaling temperature decrease) to red (temperature too high). The clean green color corresponds to the optimum indoor temperature (+ 21 ° C).
The LED diode used in the system has a milky lens, which ensures a very nice effect. It can be strengthened by using an additional diffusing element, for example: a matte or milk plexiglass plate.

The device is especially recommended for beginner electronics - meteorologists
