Humidity & Temperature Sensor

Sensirion's SHTC1 humidity and temperature sensor is specifically designed for mobile devices where size is a critical factor. The sensor measures 2 x 2 x 0.8 mm. It is based on the CMOSens Technology, which allows the sensor and the signal processing electronics to be combined on a single silicon chip to achieve small device size. Production is targeted at high volume to allow low unit prices to be achieved by economy of scale. The supply voltage of 1.8 V is also fully in line with the needs of the target industry. The specifications of the new sensor show that the size, power consumption and price reductions do not have any impact on performance. It measures relative humidity over a range of 0 to 100 %RH with a typical accuracy of ±3 %RH. The temperature measuring range is -30 to +100 °C with a typical accuracy of ±0.3 °C. The sensor is fully calibrated, has a digital I²C interface, and is suitable for reflow soldering. This makes it compatible with standard industrial mass production processes for electronic modules.
