Hello everyone,
I have built a device which takes the temperature input of a DS1820 One Wire sensor and controls a heat source accordingly.
This is a critical process. Thats why I want to get a second sensor for redundancy.
This is what should happen:
-Both Sensors are hooked up to the Arduino
-Both Sensors are working, temperature should be read from the first sensor
-One sensor fails, temperature should now be read from the other sensor
-Both Sensors fail, shut off heating.
How could I accomplish this?
Thanks!
