AHT20 Integrated Temperature And Humidity Sensor


Key Benefits:

• Full calibration
• Digital output, I2C interface
• Excellent long-term stability
• SMD package suitable for reflow soldering
• Quick response and strong anti-jamming capability


General Information of AHT20 Sensor:

As a new generation of temperature and humidity sensors, AHT20 sets a new standard in terms of size and performance: a two-row flat pin less SMD package suitable for reflflow soldering, bottom face 3x3mm, height 1.0mm. The AHT20 sensor outputs calibrated digital signals in standard IIC format.


Advantages of AHT20 Sensor:

AHT20 sensor 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. 

The performance of AHT20 has been greatly improved or even exceeded the previous generation of temperature and humidity sensors, and its performance is more stable in harsh environments.

Each sensor from Saftty 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 benefit from cutting-edge energy-saving operation modes.


Applications of AHT20 Sensor

The applications of AHT20 sensors are wide: HVAC, dehumidifiers, 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.
