SHT20Digital Temperature and Humidity SensorProduct Summary
The SHT20 humidity and temperature sensor of Sensirion has become an industry standard in terms of form factor and intelligence: Embedded in a reflow solderable Dual Flat No leads (DFN) package of 3 x 3mm foot print and 1.1mm height it provides calibrated, linearized sensor signals in digital, I2C format.
The SHT2x sensors contain a capacitive type humidity sensor, a band gap temperature sensor and specialized analog and digital integrated circuit – all on a single CMOSens ® chip. This yields in an unmatched sensor performance in terms of accuracy and stability as well as minimal power consumption.
SHT20Digital Temperature and Humidity SensorFEATURES
• Fully calibrated
• Digital output, I2C interface
