SHTW2 Datasheet | Sensirion

Data Sheet SHTW2 WLCSP Humidity and Temperature Sensor IC - Ultra-small flip chip package: 1.3 × 0.7 × 0.5 mm3 - Fully calibrated and reflow solderable - Ultra-low power consumption - Power-up and measurement within 1 ms - 1.8 V supply voltage - Typical accuracy: ±3 %RH and ±0.3 °C Product Summary The SHTW2 is a digital humidity and temperature sensor in a flip chip package. This type of package opens up a new category of ultra-small humidity sensors which are suitable for applications with the tightest space constraints. At the same time, the flip chip package impresses with its pure simplicity. The sensor is based on Sensirion’s CMOSens® technology, which offers a plete sensor system on a single chip, consisting of a capacitive humidity sensor, a bandgap temperature sensor, analog and digital signal processing, A/D converter, calibration data memory, and a digital munication interface supporting I2C fast mode. The sensor covers a humidity measurement range of 0 to 100 %RH and a temperature measurement range of -30 to 100 °C with a typical accuracy of ±3 %RH and ±0.3°C. The operation voltage of 1.8 V and the low power consumption make the SHTW2 suitable for mobile or wireless applications running on the tightest power budgets. With the industry-proven quality and reliability of Sensirion’s humidity and temperature sensors and constant accuracy over a large measurement range, the SHTW2 offers an unprecedented performance-to-price ratio. Tape and reel packaging together with suitability for standard SMD assembly processes make the SHTW2 predestined for high-volume applications.
