Seeed Studio launches the Grove all-in-one environmental sensors featuring Sensirion’s SEN54 and SEN55 environmental sensor nodes.

The environmental sensors detect multiple indoor air quality parameters and are designed for HVAC and air quality applications.

Many people are unaware of the potential negative health impacts of poor indoor air quality. Exposure to air pollution can lead to various short-term effects like headaches and throat irritations and long-term health issues like respiratory diseases.

As we spend around 80% of our lives indoors, it is important to know the indoor air quality and reduce air pollution to ensure an ideal and safe environment for a healthy life.

The Grove all-in-one environmental sensors detect various pollution indicators and can be used to monitor air quality in enclosed spaces. The Grove environmental sensor SEN54 measures environmental parameters like VOC (volatile organic compounds), particulate matter as well as humidity and temperature.

In addition to these parameters, the Grove environmental sensor SEN55 also detects nitrogen oxides (NOx). The integrated ambient sensor assembles 8 types of data signal output and is designed for HVAC and air quality applications.

“Sensirion has been providing various chipsets for data collection, which enable global developers to get insights from the data,” added Eric Pan, Founder and CEO of Seeed Studio. “At Seeed Studio, we have been delivering hardware solutions for the global IoT ecosystem since 2008. We are happy to apply Sensirion’s new technologies to our IoT modules and devices. Together, we will enable global developers to build scalable IoT solutions efficiently and empower them to digitalise the world.”

With the Grove cable, the environmental sensors can simply be connected through a single interface with existing development platforms from Seeed Studio, Arduino, Raspberry Pi and many more.

The single-cable solution also allows device manufacturers integration in applications, saving design-in efforts and assembly costs. To help developers get started with prototyping, Seeed Studio offers a tutorial platform with documentations explaining how to utilise the Grove all-in-one environmental sensors to connect to Arduino, Raspberry Pi and STM32.

“We are proud of the strong relationship we have built with Seeed Studio during the last years. Seeed Studio’s development platforms are designed to assist experimentation and prototyping with our innovative sensors in different applications, helping our customers reduce development effort and speeding up hardware design”, says Johannes Winkelmann, Director Developer Experience at Sensirion.
