Product Overview	The Fixed Livestock House Ammonia Sensor is designed for continuous monitoring of NH3 concentration in commercial livestock buildings. It provides real-time air-quality information for pig houses, poultry houses, dairy barns and other intensive animal-production facilities. The sensor uses electrochemical detection technology to measure ammonia concentration and converts the measurement into a standard electrical signal for connection to compatible climate controllers, ventilation systems, PLC equipment or centralized farm-management platforms. For commercial pig farm construction and renovation projects, the sensor can be integrated with exhaust fans, air inlets, minimum-ventilation systems and environmental controllers to create an automated livestock-house climate management solution.
Key Features	Continuous NH3 Monitoring: Provides 24-hour ammonia concentration monitoring inside livestock houses, reducing dependence on occasional manual measurements. Electrochemical Sensing Technology: Uses a dedicated electrochemical sensing element for continuous detection of ammonia in agricultural environments. 0–100 ppm Detection Range: The reference configuration provides a measurement range suitable for routine livestock-house air-quality monitoring. 4–20 mA Signal Output: Standard industrial analog output facilitates integration with livestock climate controllers, PLC systems and building automation equipment. Automatic Ventilation Integration: Ammonia concentration can be used as an additional control parameter for compatible ventilation and environmental-management systems. Fixed Wall-Mounted Installation: Permanent installation provides consistent monitoring at a representative location within the livestock building. Sealed Agricultural Enclosure: Designed for demanding farm environments where dust, humidity and corrosive gases may be present. Suitable for New and Existing Farms: Can be incorporated into new pig farm construction, poultry-house projects or modernization of existing livestock facilities. Low-Voltage Operation: The reference system operates from a 12–24 VDC power source through the appropriate sensor power arrangement. Commercial Farm Scalability: Multiple sensors can be installed across different livestock rooms, production zones or buildings according to project requirements.
Structural Components	Electrochemical NH3 Sensing Element: Responds to ammonia present in the surrounding air and generates an electrical signal related to gas concentration. Signal Conditioning Circuit: Processes the sensor response and converts it into a stable output suitable for environmental controllers. Protective Enclosure: Sealed housing protects internal electronic components from typical livestock-house dust and humidity. Gas Sampling Area: Allows surrounding barn air to reach the sensing element while helping protect the internal components. Wall-Mounting Points: Enable secure fixed installation on walls, posts, equipment panels or steel structure building members. Power Connection: Provides low-voltage power to the sensor and electronic processing components. 4–20 mA Output Interface: Transmits the measured ammonia concentration to a compatible controller or monitoring system. Optional Control Accessories: Power modules, controller interfaces, signal wiring and mounting accessories can be configured according to project requirements.
Working Principle	Air inside the livestock house reaches the electrochemical sensing element through the sensor's sampling area. When ammonia interacts with the sensor, an electrochemical reaction produces an electrical response proportional to the NH3 concentration. The internal electronics process this response and convert it into a standardized 4–20 mA output signal. A compatible livestock environmental controller interprets the signal and displays or records the corresponding ammonia concentration. When integrated into an automatic ventilation system, ammonia measurements can be evaluated together with temperature, relative humidity, carbon dioxide, static pressure and other environmental parameters. The controller can then operate ventilation equipment according to the programmed environmental strategy, helping maintain suitable air exchange while supporting efficient climate management.

Installation & Maintenance	Before installation, review the livestock-house layout, ventilation direction, animal zone and environmental-control system. Select a representative monitoring location rather than a position directly beside a fresh-air inlet, exhaust fan or unusually concentrated local ammonia source. Secure the sensor enclosure to a stable wall, steel structure member, equipment support or other suitable mounting surface. The installation position should allow free air circulation around the sensing area and convenient access for inspection. Route the low-voltage power and 4–20 mA signal cable separately from high-power motor cables where practical to reduce electrical interference. Connect the sensor to the compatible environmental controller according to the wiring diagram. Verify power polarity, signal wiring and controller input configuration before commissioning. After installation, confirm that the controller receives a stable sensor signal and that the ammonia value responds correctly to the configured measurement range. During routine operation, keep the sensing area free from excessive dust and contamination. Avoid direct high-pressure washing of the sensing element or electrical connections. Electrochemical sensors should be periodically inspected and verified according to the maintenance instructions for the selected model. Sensor replacement or calibration requirements depend on operating conditions and manufacturer recommendations.
