Honeywell HumidIcon™ Digital Humidity/Temperature Sensors, HIH8000 Series, are digital output-type relative humidity (RH) and temperature sensors combined in the same package. These sensors provide an accuracy level of ±2.0 %RH and a temperature accuracy level of ±0.5 °C. • Industry-leading long-term stability • True temperature-compensated digital I2 C or SPI output • Industry-leading reliability • Energy efficiency • Lowest total cost solution • Ultra-small package size and options • Other accuracies available: ±1.7 %RH (HIH9000 Series), ±3.0 %RH (HIH7000 Series), ±4.0 %RH (HIH6100 Series), and ±4.5 %RH (HIH6000 Series) 

The SS351AT, SS451A, and SS551AT sensor ICs are small and versatile digital Hall-effect devices operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to either a North pole or a South pole. These products have a typical operating point of 85 G at 25 °C [77 °F]. Because they can be operated by a North pole or a South pole, they do not require the magnet polarity to be identified, thus making the installation easier and potentially reducing the system cost. These omnipolar sensors are sensitive and flexible devices designed to meet a wide range of potential applications.
