About HiLetgo 2pcs AHT21 I2C IIC High Precision Digital
Description: AHT21 a new generation of temperature and humidity sensors, sets a new standard in size and intelligence: it is embedded in a dual-row flat leadless SMD package for reflow soldering with a 4 x 5mm bottom and a height of 1.6mm. The sensor outputs a calibrated digital signal in standard I2C format. The AHT21 is equipped with a newly designed ASIC-specific chip, an improved MEMS semiconductor capacitive humidity sensing element and a standard on-chip temperature sensing element. Its performance has been greatly improved beyond the reliability level of previous generation sensors. The first generation of temperature and humidity sensors have been improved to make them more stable in harsh environments. Note: Please make sure put it in the environment of humidity greater than 80% for 12 hours to ensure the accuracy is restored before using. Characteristics: 1. Module size: 16*11 mm 2.
