Ive finished building a Thermometer for my Pick-up.
The sensor/probe is a BC547.
Question is ,whats the useful resolution for this type of typical transistor? Most places Ive looked offer 20-70C as a general range.
Essentially if it can reliably given me accurate readings of -30C to 105C I'll be happy,If not I'll switch it out for a LM35..Just means I have to wait to put it in the truck
