AHT10 Technical Manual
Temperature and Humidity Sensor
• Full calibration
• Digital output, I C interface
• Excellent long-term stability
• SMD package suitable for reflow soldering
• Quick response and strong anti-jamming capability
Product Overview
AHT10, as a new generation of temperature and
humidity sensors, has established a new standard
in size and intelligence. It is embedded in a double
row flat no-lead package suitable for reflow
soldering, with a bottom of 4 x 5 mm and a height
of 1.6 mm. The sensor outputs calibrated digital
signals in standard I C format.AHT10 is equipped
with a newly designed ASIC chip, an improved
MEMS semiconductor capacitive humidity sensing
element and a standard on-chip temperature
sensing element. As a result, the performance
of the new generation of temperature and humidity
sensors has greatly improved or even exceeded
that of the previous ones with more stability in
harsh environments.
Application Scope
HVAC system, dehumidifier, test and inspection equipment, consumer goods, automobiles, automatic control,
data recorder, weather station, household appliances, humidity regulation, medical and other related
temperature and humidity detection and control.

Each sensor is calibrated and tested, with product
batch number printed on the surface of the product.
Due to the improvement and miniaturization of the
sensor, its cost-effective ratio is higher, and
finally all equipment will benefit from the cutting-
edge energy-saving operation mode.
