Product Overview	The Fixed Livestock House Air Velocity Sensor is designed for continuous airflow monitoring in pig houses, poultry houses, cattle barns, ventilation ducts, air inlets, exhaust systems, and other agricultural buildings. It provides real-time air velocity data for evaluating ventilation performance and supporting livestock environmental control. The reference YF500 platform uses a streamlined stainless steel sensing probe designed to reduce airflow disturbance and provide stable measurement. The sensor measures air velocity from 0 to 30 m/s with 0.1 m/s resolution and reference accuracy of ±3%. Standard RS485 Modbus RTU communication enables connection to livestock environmental controllers, PLC systems, SCADA platforms, data loggers, and IoT gateways. LoRaWAN, WiFi, and 4G configurations are also available for wireless or remote farm monitoring applications.
Key Features	Continuous fixed-point air velocity monitoring for livestock ventilation systems. 0 to 30 m/s reference measurement range for low- and high-velocity airflow applications. 0.1 m/s resolution with a starting air velocity of approximately 0.1 m/s. Reference measurement accuracy of ±3%. Streamlined stainless steel probe helps reduce disturbance to the measured airflow. IP67-rated transmitter housing supports demanding agricultural environments. Standard RS485 Modbus RTU interface simplifies integration with farm controllers and PLC systems. Optional LoRaWAN, WiFi, and 4G communication supports smart-farm monitoring. Flange installation provides stable mounting in ventilation ducts and airflow passages. Suitable for pig farms, poultry houses, livestock barns, greenhouses, and agricultural ventilation projects.
Structural Components	The typical system consists of a stainless steel air velocity probe, streamlined sensing head, probe shaft, installation flange, transmitter housing, signal-processing electronics, power and communication terminals, cable connection, and mounting components. The sensing probe is positioned directly in the airflow path while the transmitter electronics process the measurement and provide a digital communication signal. The corrosion-resistant stainless steel probe and flame-retardant ABS transmitter enclosure are designed for long-term fixed installation.
Working Principle / Structural Principle	The sensing probe continuously detects air movement passing across the measurement element. The resulting signal is processed electronically and converted into a real-time air velocity value. When installed in a livestock ventilation duct, air inlet, exhaust passage, or representative animal-zone monitoring point, the sensor provides continuous airflow data that can be transmitted to an environmental controller or monitoring platform. The airflow information can be used to evaluate ventilation performance, identify abnormal airflow conditions, compare different livestock-house zones, and support automatic environmental management.

Applications	Pig house ventilation monitoring. Broiler, layer, and breeder poultry houses. Cattle barns and calf housing facilities. Livestock-house air inlet monitoring. Exhaust fan and ventilation duct airflow monitoring. Minimum ventilation and tunnel ventilation systems. Livestock environmental control systems. Greenhouses and agricultural climate-control facilities. Steel structure livestock buildings. Smart farm and agricultural IoT projects.
Customization Options	SHEWUYOU can configure fixed air velocity monitoring solutions according to livestock species, house dimensions, ventilation mode, air inlet arrangement, fan configuration, monitoring zones, and farm automation architecture. Available configurations include RS485 Modbus RTU, LoRaWAN, WiFi, and 4G communication. Probe installation arrangements, cable configuration, mounting accessories, IoT gateways, data loggers, and environmental controllers can be supplied according to project requirements. Special measurement ranges and system configurations are available upon request and can be designed according to local climate and farm conditions.
Installation & Maintenance	Install the sensing probe at a representative airflow monitoring point and align it correctly with the direction of air movement. Flange mounting can be used for ventilation ducts and fixed airflow passages, while wall or pipe mounting can be selected according to the project layout. Avoid locations immediately beside structural obstructions, sharp duct bends, fan blades, or other components that may create highly turbulent and unrepresentative airflow unless the purpose is to monitor that specific location. For livestock houses, periodically inspect the probe for dust, feathers, feed particles, and other contamination that could affect measurement. Clean the probe carefully without damaging the sensing element and inspect the enclosure, cable, mounting hardware, and communication connection during routine farm maintenance.
Project Cases	The Fixed Livestock House Air Velocity Sensor can be integrated into complete pig farm, poultry house, cattle barn, and agricultural ventilation projects. Typical systems combine fixed air velocity sensors with temperature and humidity sensors, CO2 transmitters, ammonia detectors, differential pressure sensors, environmental controllers, variable-speed fans, air inlets, cooling pads, and centralized farm monitoring platforms. For large commercial livestock projects, multiple sensors can be positioned at representative air inlets, animal zones, ventilation ducts, or exhaust sections to evaluate airflow distribution and support ventilation system commissioning and long-term environmental management.
