| Market Reality | - | The DS18B20 is the temperature sensor of the 1-Wire world - one wire, no calibration, everywhere from industrial probes to aquarium controllers - and it is also the most counterfeited sensor on the market, with a thousand-part study across seventy marketplace vendors finding almost all of it fake. The parts that circulate as DS18B20 are a zoo: near-enough clones, downgraded dies, and hybrids with supercaps instead of EEPROM. What makes the situation workable is that the genuine family is well documented and behaviorally distinguishable: power-up readings, ROM patterns, conversion timing and the marking style all separate the descendants of the original from the imitations - and the programmatic tells cost a bench minute to check. |
