First Digital Humidity Sensor! Description:
Sensirion presents the world with the first digital humidity and temperature sensor. The tiny SMD sensor module (mass: 7.5 x 5 x 2.5mm, Lx W x H) transmits a calibrated digital signal to measure the relative humidity and temperature. In addition, owing to full calibration and digital output, the humidity and temperature sensors guarantee extremely favourable system costs, a high degree of user-friendliness and excellent long-term stability. The tiny CMOSens technology based sensor module (mass: 7.5 x 5 x 2.5 mm, L x W x H) transmits a fully calibrated digital signal to measure relative humidity (+/- 3.5% RH, +/- 2% on request) and temperature (+/- 0.5�C @ 20�C). In this way, the customer is spared the elaborate and cost-intensive calibration that is associated with conventional capacitive humidity sensor elements. The SHT11 humidity sensor can be directly connected to a microcontroller using a digital 2-wire interface, which in turn signifies simplest system integration and reduced costs. Furthermore, the SMD packaging of the sensor module is extremely suitable for high-volume OEM applications. CMOSens� technology is optimised for excellent long-term stability and extremely low drift, constituting crucial customer advantages for sophisticated applications, e.g. in the automobile industry or the building automation industry. A further advantage � e.g. for transmitter manufacturers � is the extremely short response time (4 sec) and the wide range of application from �40� to 120�C. Due to its capacity for low power applications (up to 1 micro W!), the SHT11 ultimately opens up new area of application for battery-operated measuring instruments or consumer goods.First Digital Humidity Sensor! was added in May 2002
