engineering.nyu.edu– A current carrying conductor in a magnetic field experiences a force (e.g. galvanometer) • Curie-Weiss Law – There is a transition temperature at which ferromagnetic materials exhibit paramagnetic behavior • Faraday’s Law of Induction – A coil resist a change in magnetic field by generating an opposing voltage/current (e.g ...
Programmable Resolution 1-Wire Digital Thermometer
cdn.sparkfun.comSince the operating current of the DS18B20 is up to 1.5 mA, the DQ line will not have sufficient drive due to the 5k pullup resistor. This problem is particularly acute if several DS18B20s are on the same DQ and attempting to convert simultaneously. There are two ways to assure that the DS18B20 has sufficient supply current during its active ...
