Maxim Integrated

Maxim Integrated makes the iButton® data loggers: small, rugged, self-contained units that measure and store readings in protected memory at a rate set by the user. HenSistemas carries the Thermochron temperature loggers (DS1921G, DS1922L, DS1922T and the high-temperature DS1922E) and the Hygrochron DS1923, which measures temperature and humidity.

There are also the HS141921G and HS1922L versions, resin-coated and water-resistant to IPX8 for continuous immersion, and the DS9107 capsule, which shields an iButton from moisture, solvents and pressure.
