Innotecho Develops and Launches Ammonia Sensor for Smart Farms



Innotecho Co., Ltd. (CEO In-ho Kim), a specialized manufacturer of gas sensors and gas safety devices, has announced that it has developed and commercialized an ammonia sensor for smart farms after approximately six months of research.



The newly developed ammonia sensor, verified by the Korea Agency of Education, Promotion and Information Service in Food, Agriculture, Forestry and Fisheries (EPIS) in accordance with KS X 3279 standards, can accurately detect ammonia concentrations ranging from 0 to 100 ppm. It is also equipped with RS-485 Modbus communication functionality. In particular, Innotecho applied its independently developed hot-wire type semiconductor sensor technology to this product. This sensor is praised for its superior selectivity, long lifespan, and highly linear response within the 0–100 ppm detection range, ensuring outstanding performance.



Another key feature of the product is its compliance with smart farm standard specifications, which allows for compatibility with ICT equipment that follows smart farm requirements.



Innotecho plans to conduct a pilot application of this hot-wire type semiconductor ammonia sensor this month at a pig farm located in Sancheong County, Gyeongnam Province.



CEO In-ho Kim stated, “Conventional pigsties have primarily used electrochemical gas sensors, but many users voiced concerns over their short lifespan. By developing and applying a hot-wire type semiconductor gas sensor that is more robust in pigsty environments, we expect to resolve these customer inconveniences.” He added that this development was carried out under the Agricultural Technology Promotion Agency’s ICT Equipment Standardization Support Program.



Founded in January 2021, Innotecho has developed a carbon monoxide (CO) detector, participated in a pilot project for a fire detection and prevention system at Namdaemun Market, and launched a smart gas alarm. The company was also selected for and completed a national R&D project on hydrogen sensor development, conducted field testing of hydrogen and oxygen sensors within water electrolysis facilities with Korea East-West Power, and obtained FCC certification in the United States.



In addition, this year Innotecho plans to release smart livestock-use carbon dioxide (CO₂) and oxygen (O₂) sensors in the second half, and is also developing drone-mounted gas sensors with the aim of attracting investment from Catalonia, Spain.
