Definition
Livestock and poultry house environmental monitoring focuses on indicators such as temperature, humidity, ammonia, hydrogen sulfide, carbon dioxide, and negative pressure, which are used for ventilation, heating, and spray linkage to reduce stress and disease risks. Large-scale farms have multiple buildings in remote locations, making wired network construction costly. Cellular IoT SIM cards enable controllers and sensors to quickly connect. Once data is uploaded to the cloud, headquarters can perform benchmarking management and remote diagnostics.
Ammonia sensors need regular calibration, and deployment points should represent livestock activity areas rather than locations with insufficient representation such as hallways.
Technical Features
High dust environments require protection levels and self-cleaning designs; cellular antennas should be kept away from high-power fan frequency interference sources. Alerts should be tiered: life-threatening alerts should be sent immediately, while trend-type alerts should be summarized in daily reports.
SimtoLink supports batch card templates, data pools, and remote number programming, suitable for centralized procurement by group farming units; online rate monitoring helps detect buildings with weak coverage in advance.
Use Cases
Pig, laying hen, dairy cow, and beef cattle barns. Linking with precise feeding and manure treatment systems can optimize overall energy efficiency.
Biosecurity areas should restrict external equipment from accessing the production network, and cellular channels need to be isolated from the office network.
Deployment and Operation Recommendations
During the project implementation phase, enterprises should bind the IoT SIM card numbers to device serial numbers, installation locations, power supply methods, and maintenance responsible persons one-to-one, and sync this information into the asset and operation system to form a traceable link from card issuance, modification, activation, suspension to eventual cancellation. For equipment involving cross-province allocation or cross-border delivery, roaming charges, real-name registration policies, and local data compliance requirements should be evaluated in advance. It is recommended to choose solutions with predictable costs that support remote network switching or eUICC, reducing the frequency of on-site disassembly, and reserving spare cards and emergency replacement processes to shorten fault recovery time. For terminals received in bulk, it is recommended to perform sampling network verification covering connectivity and charges before activating the entire batch, to reduce rework costs.
In terms of cybersecurity, it is recommended to configure dedicated APN or VPDN tunnels for production or critical infrastructure terminals, converge north-south traffic to enterprise-controllable boundaries, and link with identity authentication, bastion host remote maintenance, and operation auditing; for remote control and parameter writing capabilities, hierarchical authorization, time windows, and dual-person review should be set. Regular drills for weak network and primary/backup link switching should be organized, recording latency, packet loss, and recovery time as technical references for MLPS (Multi-Level Protection Scheme) assessment, industry regulatory inspections, or internal risk control reviews. For third-party outsourced operations, minimum permissions, session recording, and key custody responsibilities should be clarified to avoid account sharing.
In daily operations, card management platforms should be used to continuously track online rates, abnormal traffic, dormant terminals, and data plan utilization, integrating alarms with the ITSM work order system to achieve automatic ticket assignment and closure. SimtoLink can split data pools for enterprises by factory, line, or business domain, providing bulk device suspension/resumption, API integration, and billing allocation capabilities, supporting visibility, control, and sustainable cost reduction at large-scale points, while aligning card management insights with project budgets and cost centers to improve transparency.
