An ATtiny10 Thermometer PCB #Thermometer #Making @MicrochipMakes @technoblogy

Technoblogy posts a build of a thermometer using an ATtiny10 microcontroller, a DS18B20 1-wire thermometer sensor and a bicolor LED on a small round printed-circuit board.

ATtiny10-based thermometer, flashes the temperature on a bi-colour LED. It consists of an ATtiny10, a DS18B20 1-wire temperature sensor, and a bi-colour LED, and fits on a printed circuit board 19mm (0.75″) in diameter including a 12mm CR1225 button cell. To avoid the need for a digital display, and minimise current consumption, the thermometer pulses the temperature as a series of red or green flashes on the bi-colour LED.

It’s based on my earlier project ATtiny10 Thermometer, which also gives details of the way in which temperatures are encoded. I designed it so I could seal it in a small waterproof enclosure and put it outside the window, allowing me to see the outdoor temperature from inside. Alternatively it would make an interesting pendant.
