AHT20 Integrated temperature and humidity Sensor

1.Product Overview

AHT20, 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 3 x 3 mm and a height 

of 1.0 mm. The sensor outputs calibrated digital signals in standard IAHT20, 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 3 x 3 mm and a height of 1.0 mm. The sensor outputs calibrated digital 

signals in standard I As a new generation of temperature and humidity sensors, AHT20 sets a new standard in terms of 

size and performance: a two-row flflat pin less SMD package suitable for reflflow soldering, bottom face 3x3mm, height 

1.0mm.The sensor outputs calibrated digital signals in standard IIC format.

AHT20 is equipped with a newly designed ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity 

sensor element and a standard on-chip temperature sensor element. Its performance has been greatly improved or 

even exceeded the reliability level of the previous generation of sensors. A generation of temperature and humidity

sensors have been improved to make their performance more stable in harsh environments.

Each sensor is calibrated and tested, and the product lot number is printed on the surface of the product. Due to 

improvements and miniaturization of the sensor, it is more cost-effective, and ultimately all devices

will benefifit from cutting-edge energy-saving operation modes. Due to the improvement and miniaturization of the sensor, 

its cost-effective ratio is higher, and finally all equipment will benefit from the cuttingedge energy-saving operation mode.

2.Application Scope

HVAC, dehumidifier, testing and inspection equipment, consumer products, automobiles, automatic control, data loggers, 

weather stations, home appliances, humidity control, medical and other related temperature and humidity detection and 

control.
