“…Based on the literature, a long-time interval for each measurement is required. In detail, Von Jasmund et al [40] reported the need of 30 min for each measurement and Rom and Zhang [36] reported measuring periods of 12.5 to 25 minutes. These recommendations derive from studies carried out only in laboratory conditions without any assessment in field conditions.…”

“…De Dräger Polytron C300, ook verkrijgbaar onder de naam DOL-53, is een sensor die is ontwikkeld voor de veehouderij in plaats van voor de industrie, maar vergelijkbare prestaties levert op basis van nauwkeurigheid in het laboratorium (Von Jasmund et al, 2022) (Zhuang et al, 2020).…”

“…They found an overprediction of the NDIR sensors at 60 ppm and concluded that the sensors were suitable to monitor single-point or averaged spatial CO 2 concentrations in livestock barns. von Jasmund et al [16] tested two types of NH 3 sensors in the lower-price segment (Polytron 8100 and C300) under laboratory conditions with a calibration gas and humidity generator. The tested sensors measured NH 3 following an electrochemical principle; one sensor could be purchased for roughly EUR 1000.…”

A barn’s climate is vital for animal welfare and emissions control, including greenhouse gases like methane (CH4) and carbon dioxide (CO2) and environmental gases like ammonia (NH3). The goal of this study was to investigate a developed low-cost online tool for monitoring barn climate and air pollutant emissions (OTICE) in naturally ventilated barns. OTICE employed a wireless sensor network with low-cost sensors for gases and climate variables, allowing scalable use across multiple barns. We evaluated the sensors for CO2, NH3, and CH4 for accuracy, both in controlled lab conditions and in a dairy barn in Germany, where measurements were carried out continuously for a duration of 12 days. For the averaged concentration levels over the measurement period, the low-cost sensors agreed well with the reference system, with relative deviations lower than 7% for all three gases, with maximum peak deviations up to 32% for CO2, 67% for NH3, and 65% for CH4, with strong Spearman correlations for CO2 and NH3 (ρCO2 = 0.8, ρNH3 = 0.68) and a rather weak correlation for CH4 with ρCH4 = 0.24. Further calibration and stability investigations are required, especially for CH4 sensing. However, the overall good results for NH3 and especially CO2 measurements indicate a huge potential of the low-cost system as a valuable tool for monitoring relative NH3 emission levels and the measurement of air exchange rates in naturally ventilated barns.
