What Spec Sensors does

Spec Sensors, founded in 2012 and headquartered in Newark, California, manufactures printed electrochemical gas sensors designed for IoT, indoor air quality, industrial safety, and connected device applications. The company operates as a division of Interlink Electronics (NASDAQ: LINK), with additional offices in Fremont and Camarillo, California, and a workforce of 11-50 employees.

Its core technology is screen-printed electrochemical sensor elements, a manufacturing approach that enables low-cost, compact gas detection modules with operational lifetimes exceeding 10 years. The product portfolio spans individual sensor elements priced from $20, AGS series gas sensor modules ($65-$102), DGS2 digital gas sensor modules ($99-$370), and complete instruments starting at $59, covering detection of gases including CO, NO2, H2S, SO2, and O3. Recent 2025 product launches include high-sensitivity sensor variants and a Total Breathing Module (TBM) targeting breath analysis applications. UL2034 certification and RoHS compliance support entry into regulated safety and environmental end markets.

Spec Sensors generates revenue through direct e-commerce, distribution via DigiKey, and historical crowdfunding via Indiegogo. The company has secured partnerships with Intel, The Weather Company, Seeed Studio, and Motorola, and received NSF funding support. Its customer base includes IoT developers, OEM integrators, and institutional deployments such as the Array of Things urban sensing initiative in Chicago.
