Humidity measuring range: 0---100%RH Humidity measuring precision: ±4.5%RH Temperature measuring range: -40---123.8 Temperature measuring precision: ±0.5 Working voltage: 2.2--5.5VDC Relative humidity and temperature measuring with dew point output Complete calibration digital output Easy interface 2-wire£¬ fast responding Very-low-consumption automatic dormancy Excellent long-tern stability The sensor utilizes CMOSens technology to insure products with high reliability and long-tern stability. It consists of one capacitive polymer element to measuring humidity and a band gap element to detect temperature£¬ connecting with a 14 bit converter and a 2-wire digital interface in the single chip without gap. So that the product has features of low-consumption£¬ efficient procession £¬ strong anti-interference capacity and so on.
