Sensirion has released a humidity and temperature sensor geared for mobile devices where size is a critical factor. According to the company, the SHTC1 has a footprint of 2 x 2 x mm. In addition, the sensor is based on the proven CMOSens technology that 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 1.8V is also fully in line with the needs of the target industry.

The specifications of the 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 0-100 per cent RH with a typical accuracy of ±3 per cent 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, said the company.
