This dual-purpose sensor from Honeywell measures both relative humidity and temperature for versatile use. It has an Inter-Integrated Circuit (I²C) interface that employs an Acknowledge (ACK) and Not Acknowledge (NACK) feature for efficient communication between the receiver and transmitter. This means it provides more accurate readings in a simpler package. Its digital output is easy to read and doesn't require any external software for conversion.
Thanks to its 14-bit humidity and temperature sensor resolutions, this device can detect the slightest changes in relative humidity and temperature. This makes it useful in sensitive applications, such as incubators and microenvironments.

• Condensation-resistant construction for safe use in moist areas
• Low current draw of 650μA in full operating mode and 1μA in sleep mode for optimal energy efficiency
• Wide operating temperature range of -40°C to +100°C for use in demanding environments

• Telecommunication cabinets
• Weather stations
• Grain drying systems
• Air compressors

Relative humidity is the amount of water vapour present in the air expressed as a percentage of the amount needed for saturation at the same temperature.
