Product overview

AHT10, the new generation of temperature and humidity

sensors sets a new standard in size and intelligence: it is

embedded for reflow soldering

The dual-row flat leadless SMD package has

a 4x5mm bottom and a height of 1.6mm. The sensor

outputs a calibrated digital signal in standard I2C format.

The AHT10 is equipped with a newly designed

ASIC- specific chip, an improved MEMS semiconductor

capacitive humidity sensing element and a standard on-

chip temperature sensing element. Its performance has

been greatly improved beyond the reliability level of the

previous generation of sensors. The first generation of

temperature and humidity sensors have been improved to

make them more stable in harsh environments.

Each sensor is calibrated and tested with a product

lot number printed on the surface of the

product. Thanks to improved and miniaturized

sensors, it is more cost-effective and ultimately all

equipment will benefit from cutting-edge energy-

saving operating modes.
