This thermometer is a digital clock with date thermostat made on PIC16F628 (A) / PIC16F84 (A), micro-chip temperature sensor and DS1631. (Nn [0 .. 59]) ([0 .. 23] H:), minutes are available on (TT: [1..days/month]), month, date (dn [1 .. 12] ), the year of the date (dY: [0 .. 99], where 0 is 2000), date (DT: [1.2], if you show the letters, the month when two numbers in use) for the time show time (TT: [2 .. 99]), the time to set the date (td [0 .. 99]), the temperature display shows the time: low (TE [0 .. 99]), thermostat (TL: [0 ..] ยบ)Thermostat ([tl .. 60] °) is launching the thermostat low and very high (TT: [01:03]), the second length in microseconds (Sh: SL [0 .. FF]), timer: TT and TE TD are in seconds. If TD and / or tea 0, then the date and / or temperature do not appear. TT can not be found and tea td PIC16F84 project for reasons of space and their default values tt = 8, dt = 2, TE = 3. The year is not indicated, but you need to calculate days per month. The temperature function, which is an LED that is activated by ToutPin of the DS1631. This lets you apply a lot of hysteresis in the output response when the LED is connected. The thermostat function is configurable active low or active high. If the measured temperature meets or exceeds the TH, the thermostat is activated and remains active until the temperature drops below LT.
