Open-Source Developer Kit Reported to Ease Integration of Gas Sensing into IoT Applications
NEWARK, Calif.–Carbon monoxide alarms, air pollution monitoring, indoor air quality, and breath analysis are some of the gas sensing applications that demand high performance measurement. Electrochemical gas sensing technology is the preferred solution for these applications due to measurement performance and the ultra-low power consumption needed for battery operation. However, market adoption of electrochemical gas sensors in consumer products has been constrained by their large physical size and limitations of manufacturing them at mass market volumes.
Spec Sensors (spec-sensors.com) reports that it has overcome these limitations through a proprietary approach for manufacturing screen printed electro-chemical sensors. Its approach is said to shrink the gas sensing technology down to a size appropriate for consumer devices that can be made at the volumes and costs appropriate for the mass market. The company recently released an open-source digital gas sensor development kit to make it easier for Internet of Things developers to integrate gas sensing into their products.
Spec Sensors' open-source digital gas sensor development kit includes its digital gas sensor platform hardware, pre-configured with the UL-2034 recognized carbon monoxide sensor; a sample of each Spec Sensor for detecting other gases that can be easily exchanged with the CO sensor; and a simple Windows utility to reconfigure the digital gas sensor platform for a different sensor and log data at a 1Hz sample rate. Also included are hardware design files, including schematic, part list, and Gerber/design files; firmware source code that supports gas concentration calculation and temperature compensation; and an open-source license to use this information in any Spec Sensor-based design.
"Until recently, most accurate, stable, and specific gas sensors were not small and were difficult to make inexpensively at high volumes," said SPEC Sensors CTO Dr. Joseph Stetter, in a statement. "SPEC Sensors has solved these issues. Now, we want to make it easy for everyone to work with our sensors and make them the gas sensors for the Internet of Things."
