Product Announcement from Sensirion AG
Sensirion's new SHT2x digital humidity and temperature sensor integrate sensors and full signal processing in a 3 x 3 x 1.1-mm DFN 3-0 package. Over-moulding of the sensor chip provides excellent protection against aging and ambient conditions, and thus yields outstanding long-term stability.
The SHT2x series of humidity and temperature sensors are available in two versions. The standard version SHT21 features a typical accuracy of 2% RH over a range of 20-80% relative humidity and 0.3°C over a range of 5-60°C. In contrast to that, the high-precision version SHT25 offers a typical accuracy of 1.8% RH over a range of 10-90% relative humidity and 0.2°C over a range of 5-60°C.
The humidity sensors SHT2x are fully calibrated and provide an I2C digital interface. Digital communication mode enables a superbly low power consumption of 3μW in normal operation. Available on tape & reel, the reflow solderable SHT2x are suitable for high-volume applications. An extended quality assurance program ensures low PPM values.
