AHT10 High Precision Digital Temperature and Humidity Sensor Measurement Module I2C Communication; The sensor outputs a calibrated digital signal in standard I 2C . The AHT10 is equipped with a newly designed ASIC- chip,an improved MEMS semiconductor capacitive humidity sensing and a standard on-chip temperature sensing element. The AHT10,a of temperature and humidity sensors,sets a new standard in size and intelligence: 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 more stable in harsh environments. it is embedded in a dual-row flat leadless SMD package reflow soldering with a 4 x 5mm bottom and a height of 1.6mm. size:16 x 11mm Material:Electronic colour:blue Package Contents: 5 x AHT10 Digital Temperature and Humidity Sensor Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
