Different environmental bands by production stage
Farrowing, nursery and finishing pigs need different temperature bands. One manual setting can leave piglets cold while finishers overheat.
PIG-BARN ENVIRONMENTAL CONTROL
Smart Pig Farm
Phased Monitoring and Pig-Barn Environmental Control
Collect temperature, humidity, ammonia, dust and equipment status, then configure ventilation, cooling, heating and alert rules for farrowing, nursery, finishing and other production stages.

On site
Different production stages need different conditions
Production stages require different environmental ranges, while manual checks provide limited coverage across multiple barns.
Air quality requires measurement
Ammonia and airborne dust require suitable sensors because visual inspection does not provide a measured concentration.
Limited overnight staff coverage
Continuous temperature monitoring and configured rules can provide alerts or operate connected heating and ventilation equipment outside staffed hours.
Hills and outskirts weaken 4G
Many farms sit in hills or outskirts where 4G is weak. LoRa carries data across the farm before Ethernet backhaul takes over in the duty room.
System workflow
From barn instruments to the duty-room network
Use a farm-side field link and the duty-room uplink without relying on 4G inside each barn.
- 01
Collect barn readings
Compatible environmental instruments connect through RS485 to a barn-side Y201-L.
- 02
Carry serial data over LoRa
The transmitting and receiving Y201-L devices form the selected farm-side serial link.
- 03
Use the duty-room uplink
The receiving Y201-L connects through a serial interface to a Y201-R Ethernet gateway and the site network.
- 04
Monitor and coordinate
The application collects readings and configured alerts; matched local control equipment handles ventilation and heating actions.
Match the radio configuration to the installation country and test the link with the actual barn layout, antennas and obstructions.
Monitoring and control
Barn monitoring and equipment control
The system combines barn sensors, a LoRa field network, duty-room monitoring, equipment control and historical records.
Air quality + climate
RS485 ammonia, dust, temperature, and humidity sensors give each barn a live environmental baseline.
LoRa farm network
Y201-L nodes form a LoRa field network for scattered barns, reducing trenching and barn-side 4G dependency.
Duty room dashboard
The operator sees each barn on a big screen, with abnormal values surfaced for quick response.
Equipment linkage
Configured thresholds can operate connected fans, water curtains, manure scrapers, lighting and heat lamps through the power box.
Ethernet cloud access
Y201-R uses the duty room wired network to send data to YenGear IoT Cloud over MQTT/HTTP.
History and traceability
Batch-level trend data helps compare seasons, barns, and control strategies after a problem occurs.
Application examples
Control conditions by production stage
PigSense maps environment control to the biological needs of each production stage instead of forcing one barn rule onto each group.
Farrowing Room
Keep the sow and piglet zones within the different temperature and humidity bands their stages require.
Nursery Barn
Use stable climate trends and alarms to reduce stress during the most sensitive growth stage.
Finishing Barn
Control ventilation and temperature for efficient finishing while keeping air quality visible.
Breeding Barn
Maintain a consistent environment across breeding groups and keep the history for review.
Deployment planning
Plan the barn and duty-room links
Connect distributed barns, environmental sensors, control points and the duty-room network.
Site layout
Separate barns, ventilation equipment and a duty-room network require a layout that matches the production stages and control points.
Radio and network conditions
Barn walls, metal structures, terrain and cellular coverage affect the selected LoRa and Ethernet paths.
Field architecture
Ammonia, dust, temperature and humidity sensors can connect to Y201-L nodes over RS485. A Y201-L receiver can work with a Y201-R gateway in the duty room to send data to the cloud over Ethernet.
Operating view
The platform can present barn status, temperature and ammonia alerts, with linked equipment actions configured for the project.

FAQ
Practical answers for farm managers, integrators, and livestock technical advisors evaluating PigSense.
Can PigSense work when the farm has no 4G signal?
Barn-side data can move through the Y201-L LoRa network first, while the duty room can use Y201-R Ethernet backhaul where a suitable wired network is available. The final topology and offline behavior depend on the site.
How should ammonia sensor maintenance be planned?
Calibration and replacement depend on the sensor technology, exposure, contamination, operating range and manufacturer instructions. Treat the probe as a maintained field component and define the interval after reviewing the selected model and site conditions.
Will high humidity and dust affect the equipment?
Y201-L is specified for industrial environments and supports 5-95% RH non-condensing operation. Sensor probes should still use dust protection and receive periodic cleaning.
What can the smart power distribution box control?
Common barn circuits such as fans, water-curtain pumps, manure-scraper motors, lighting and heat lamps can be evaluated when their voltage, load, starting method, protection and manual/automatic requirements are compatible.
How far can the LoRa network cover?
Usable coverage depends on barn walls, metal panels, terrain, antenna height, node placement and relay requirements. Use the product range only as an initial reference and confirm the actual layout with a site survey or communication test.
