Product Overview
The Honeywell HumidIcon HIH7000 Series are digital relative humidity (RH) and temperature sensors designed for combined measurement in a single package. These sensors offer industry-leading reliability, accuracy of 3.0 %RH and 0.5 C, and long-term stability. They provide true temperature-compensated digital I2C or SPI output, energy efficiency with low supply voltage and sleep mode capabilities, and a low total cost of ownership. The series offers various packaging options, including SIP 4-Pin or SOIC-8 SMD housing styles, with or without hydrophobic filters, and I2C or SPI output interfaces. These sensors are suitable for a wide range of applications including industrial HVAC/R, air compressors, weather stations, telecom cabinets, incubators, grain drying systems, and medical respiratory therapy.
