Description

The AHT20, a new generation oftemperature and humidity sensors, sets a new standard insize and intelligence: it is embedded in a double-row flat pin less SMD package suitable forreflow soldering, with a bottom face of 3X3MM and a height of 1. The OMMO sensoroutputs calibrated digital signals in standard IC formatAHT20 is equipped with a new design of ASIC chips, an improved MEMS capacitivehumidity sensor semiconductor element and a standard on the piece of temperaturesensing element,its performance has been greatly improve even beyond the reliabilitylevel of the previous generation of sensors, a new generation of temperature and humiditysensor, the improved to make it more stable performance in harsh environments.
