No building on your part is needed. Only schematic and parts specification. This is a one-off build for me using point-to-point soldering or a soldered breadboard. Power supplied via 3V coin battery. When power is applied Output1 goes high, then after 1-2 seconds, Output2 goes high. Both outputs share a common ground. At 70 degrees Fahrenheit Output1 goes low. At 67 degrees Output1 goes high, then Output2 goes high. Low/high cycle repeats until power is disconnected. Very low amperage. Temperatures need not be exact, just close.
