Honeywell HumidIcon™ Digital Humidity/Temperature Sensors HIH7000 Series • ±3.
Honeywell HumidIcon™ Digital Humidity/Temperature Sensors Honeywell HumidIcon™ Digital Humidity/Temperature Sensors, HIH7000 Series, are digital output-type relative humidity (RH) and temperature sensors combined in the same package. These sensors provide an accuracy level of ±3.0 %RH.
Features and Benefits Industry-leading long-term stability* (1.2 %RH over five years) Competitive humidity sensors require a 12 hour at 75 %RH rehydration process (which requires special equipment chambers) to correct reflow temperature offset. Honeywell’s sensor also experiences an offset after reflow; however, it only requires a five-hour rehydration under ambient conditions (>50 %RH). Honeywell’s industry-leading long-term stability: • Minimizes system performance issues 0 .
Features and Benefits HIGH RESOLUTION High 14-bit humidity sensor resolution and 14-bit temperature sensor resolution within the application help the user’s system detect the smallest relative humidity or temperature change Free up PCB space. Reduce costs. True, temperature-compensated digital I2C or SPI output* Typically allows the customer to remove the components associated with signal conditioning from the PCB to free up space and reduce costs associated with those components (e.g.
Potential Applications INDUSTRIAL HVAC/R May be used to provide precise RH and temperature measurement in air conditioning/air movement systems, enthalpy sensing, thermostats, humidifiers/ dehumidifiers, and humidistats to maintain occupant comfort and ideal storage humidity/temperature while achieving low energy consumption, supporting system accuracy and warranty requirements, maximizing system uptime, and improving overall system quality.

HIH7000 Series • ±3.0 %RH Accuracy SENSOR REHYDRATION NOTICE: SENSOR REHYDRATION • Exposure to elevated temperatures, such as those experienced during solder reflow, may dry out the sensing element. It is recommended that the sensor be allowed time to rehydrate after soldering or other high temperature/dry exposures. • Exposure to these conditions will not permanently damage the sensor. It will generally return to its factory-calibrated value after rehydration.
