Sensirion AG, a digital microsensor and systems manufacturer, has developed the second generation of its wafer-lever chip-scale package (WLCSP) humidity sensor.

The SHTW2 sensor comes in a flip chip package – one of the simplest and smallest ways to package a semiconductor chip – giving the sensor a miniscule footprint.

The latest device (left) is based on the Switzerland-based corporation’s CMOSens® Technology – a complete sensor system of a single chip with a digital inter-integrated circuit (I2C) interface. The sensor is fully calibrated and covers a humidity measurement range of 0-100% relative humidity (RH) and a temperature range of -30°C to 100°C.

Due to the SHTW2’s low power consumption and 1.8V operation voltage, it is ideal for mobile phones, wearables and Internet of Things (IoT) applications, along with various other consumer electronics that are power budget conscious.

A press release stated, “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 price-performance ratio.”
