AVT1697 / 2 C

Thermometer measuring temperature in the range -55 ° C to + 125 ° C. 'Large-size', because it works with two displays of various sizes.

The first, miniature LED display with a digit height of 7mm (AVT1697 / 1), can be used to indicate temperature, e.g. in a car. The second one with displays with 27mm mark height (AVT1697 / 2) ideally suited as a temperature meter that allows it to be read from long distances, e.g. in production halls. The system should be powered with a constant voltage of 7..15V. The thermometer's work is controlled by the ATTINY2313 microcontroller. Temperature indications are updated every 2s.

The system is assembled and running.
