AHT20, a new generation of temperature and humidity sensors, establishes a new standard in size and intelligence:
it is embedded in a double-row flat, leadless SMD package suitable for reflow welding, with a base of 3 x 3mm and a height of 1.0mm.
The sensor outputs calibrated digital signals in standard I2C format.
AHT20 is equipped with a new design of ASIC chips, an improved MEMS capacitive humidity sensor semiconductor element and a standard on
the piece of temperature sensing element, its performance has been greatly improve even beyond the reliability level of the previous generation of sensors,
a new generation of temperature and humidity sensor, the improved to make it more stable performance in harsh environments.
Each sensor is calibrated and tested and has a lot number printed on the surface of the product.Improved and miniaturized sensors make it more cost-effective,
and eventually all equipment will benefit from cutting-edge energy-efficient operating modes.
Mainly used for HVAC, dehumidifier, testing and testing equipment, consumer goods, automobile, automatic control, data logger, weather station, home appliances, humidity regulation, medical and other related temperature and humidity detection and control.
