Humidity & Temperature Sensor

Sensirion presents its latest humidity and temperature sensor SHTW1, which opens up new possibilities in the wearable and mobile market with its chip-scale packaging technology. With its size and low energy consumption, the humidity and temperature sensor meets the exacting expectations of the consumer electronics industry. It is based on CMOSens Technology, which integrates the sensor component and the evaluation circuit on a single semiconductor chip. The sensor's package is no larger than the CMOSens Chip itself, yet it has the same functionality as conventional digital humidity and temperature sensors. The sensor has dimensions of just 1.3 x 0.7 x 0.5 mm. The device could soon give glasses, watches, articles of clothing or cell phones the ability to sense temperature and humidity, making it possible to integrate the measurement of our environment into every facet of our lives. The operating voltage of 1.8V and the power consumption of 2 µW at 1 measurement per second provide an optimal basis for using the sensor in small, mobile devices. It measures relative humidity across a range of 0% to 100% RH, with a typical accuracy of +/-3% RH. The temperature measurement ranges from -30 °C to 100 °C with a typical accuracy of +/- 0.3 °C. The completely calibrated sensor features an I2C interface and is reflow solderable.
