Atmosphere IoT Studio adds support for sensors from Sensirion



Blog, Platform | August 9th, 2019

Atmosphere recently added support for the SHT3x and SHTCx Digital Humidity and Multi-Pixel Gas SGPx sensors from Sensirion, enabling IoT solution builders to use the Atmosphere drag-and-drop Studio IDE to incorporate these sensors into their IoT projects.

The SHT3x Sensor is featured on the MikroElektronika SHT Click board and Adafruit SHT31-D breakout board. The SGPx sensor is featured on the Sensirion Environmental Sensor Shield and the Adafruit SGP30 Air Quality Sensor Breakout board. The SHT3x, SHTCx, and SGPx are available in the Arduino Shield form factor as well.


The SHTCx digital humidity sensors are designed especially for high-volume consumer electronics applications. These sensors are designed to overcome conventional limits for size, power consumption, and price-performance ratio, in order to fulfill the current and future requirements of the consumer electronics market.

The new digital SHT3x humidity sensor series takes sensor technology to a new level. As the successor of the SHT2x series it is determined to set the next industry standard in humidity sensing. The SHT3x humidity sensor series consists of a low-cost version with the SHT30 humidity sensor, a standard version with the SHT31 humidity sensor, and a high-end version with the SHT35 humidity sensor.

The multi-pixel gas sensor platform SGP creates new possibilities for the measurement of indoor air quality. The SGP offers a complete gas sensor system integrated into a very small 2.45 × 2.45 × 0.9 mm3 DFN package featuring an I2C interface and fully calibrated air quality output signals.The unprecedented combination of long-term stability and multi-pixel technology makes the SGP a perfect choice for indoor air quality monitoring in mobile, smart home and appliance applications.

The development team at Sensirion worked with the Atmosphere EEL (Embedded Element Library) Builder, a tool that enables any embedded sensor manufacturer to incorporate their peripheral  for use within the Atmosphere IoT Studio. Atmosphere’s partner development team can test, verify and publish these new peripherals for use by any developer with a free Atmosphere Developer account.

Johannes Winkelmann, Head of Global Developer Ecosystem & Partnerships at Sensirion, worked with the EEL Builder to create the necessary drivers and add these sensor systems to the Atmosphere Platform.  “The process was straightforward and the Atmosphere team was very helpful when we had questions. The Atmosphere Studio IDE itself makes it quick and easy for developers to integrate Sensirion sensors in combination with popular IoT development kits, boards and wireless options.”
