SLHT4-4 industrial protective temperature and humidity sensor is a sensor that measures relative humidity and temperature. It features full-range calibration, digital output, and excellent long-term stability. It does not require additional components and can be fully submerged. The sensor is manufactured using CMOSens® technology, which ensures high reliability and fast response. It is suitable for applications in data loggers, transmitters, automation process control, building control and HVAC systems.
The SLHT4-4 is an industrial‑grade temperature and humidity sensor that integrates a calibrated SHTxx element, a 14‑bit A/D converter, and a serial interface on a single chip. It is built with patented CMOSens® micro‑fabrication technology for high reliability, low power consumption (typ. 30 µW), and full immersion capability.
The manual covers product overview, technical specifications, pin‑connector interface, calibration data storage, and recommended application fields such as data acquisition, automation, HVAC, automotive, power metering, and medical equipment. It also lists available package types (surface‑mount LCC or 4‑pin through‑hole) and provides part numbers for related models. This manual is written in Chinese.
