In modern livestock farming, the air quality of the environment directly impacts the health and productivity of livestock and poultry. Ammonia (NH3), a common harmful gas in farms, primarily originates from the decomposition of animal excrement. Excessive concentrations can induce respiratory diseases and weaken the immune system in animals, affecting feed conversion rates and potentially leading to large-scale epidemics. Therefore, establishing a stable and reliable ammonia monitoring system is crucial for farm environmental management.

    Tensensor's MQ-E3-NH3 Electrochemical NH3 Sensor is a high-performance gas detection solution specifically developed for such scenarios. This sensor utilizes a constant-potential electrolysis principle, enabling linear conversion between ammonia concentration and current signal. It boasts advantages such as high sensitivity, high accuracy, and low power consumption, making it ideal for long-term, stable environmental gas monitoring in farms.

Core Product Advantages

    1. Optimized for Ammonia Detection, Precise Measurement Range

    Detected Gas: Ammonia (NH₃)

    Measurement Range: 0–100 ppm, maximum measurement limit up to 200 ppm

    Resolution: 0.5 ppm, capable of capturing trace changes in ammonia

    Response Time (T90) ≤60 seconds, providing real-time feedback on environmental changes

    2. Strong Anti-interference Capability, More Reliable Data

    In aquaculture environments, interference from other gases such as hydrogen sulfide, carbon monoxide, and ethanol is common. MQ-E3-NH3 exhibits excellent cross-interference suppression capabilities, with a response of <25 ppm to hydrogen sulfide (50 ppm) and <20 ppm to ethanol (1000 ppm), ensuring accurate and reliable ammonia readings.

    3. Strong environmental adaptability, stable and durable

    Operating temperature: -20℃～50℃

    Humidity range: 15%～90% RH (non-condensing)

    Lifespan: 2 years (in an environment with 2ppm NH₃)

    Monthly output stability <10%, good repeatability, suitable for long-term deployment

    4. Easy installation and use

    The recommended load resistance of the sensor is only 10Ω, and the circuit design is simple. It adopts a solderless design.

Application Value in Livestock Farms

    Real-time Early Warning, Prevention is Key

    By continuously monitoring ammonia concentration in the sheds, the system can issue an alarm when the concentration approaches a safe threshold, reminding managers to ventilate or clean manure in a timely manner, avoiding outbreaks of health problems in animals.

    Improved Farming Efficiency

Good air quality contributes to healthy animal growth, improves feed utilization, reduces mortality, and improves the economic benefits of the farm from the source.

    Compliance with Environmental Protection and Animal Welfare Requirements

    More and more regions are regulating emissions from livestock farms. Using MQ-E3-NH3 enables data recording and traceability, helping farms operate in compliance with regulations and enhancing the company's social responsibility image.

    Tensensor is committed to the research, development, and application of gas sensing technology. Our MQ-E3-NH3 ammonia sensor, with its reliable performance, excellent environmental adaptability, and long-term stability, has become an ideal choice for environmental monitoring in the aquaculture industry.
