Very usefull
Bought 5 of these temperature sensors. I mounted all 5 on a single one-wire bus, and arranged the sensors in a bundle to measure the same temperature. in Celsius, the sensors agreed on the first two digits, and the highest and the lowest readings showed a difference of about 0.6 degrees Celsius. That is more than adequate for my purpose, and gives great value for the money in my opinion
