Sensirion presents the world’s smallest humidity and temperature sensor, setting new standards for size, power consumption, production volume and price. The SHTC1 humidity and temperature sensor, the smallest of its sort with really big performance, is specifically designed for mobile devices. We have rigorously followed the maxim “smaller is better” and developed the world’s smallest humidity sensor, measuring just 2 x 2 x 0.8 mm. The sensor is based on proven CMOSens® Technology, which integrates the sensor and the signal processing circuitry on the same silicon chip. Production is targeted to 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 consumer goods sector.

The specifications show that the size, power consumption and price reductions do not have any impact on performance. The sensor measures relative humidity over a range of 0 to 100% 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. To facilitate successful integration of the sensor into complex applications, we also stand behind you with our many years of experience from millions of sensors in the field, and we support you with suitable application expertise.
