DGSDK Digital Gas Sensor Developer Kit 968-032 DESCRIPTION
SPEC Sensors is making it easy for Internet of Things developers to integrate gas sensing in their products. 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.
SPEC Sensors has overcome the physical size and mass market volume limitations that have constrained market adoption of electrochemical gas sensing in consumer products. The Digital Gas Sensor Developer Kit will allow OEMs to quickly integrate gas sensing into their application(s).
