Poultry Farm IoT Connectivity: Temperature, Humidity, Air Quality Monitoring – eSIM & CMP Cuts Per-Device Cost 30–40%
July 22, 2026 · 9 min read · Technical Whitepapers
Poultry farm IoT using eSIM and CMP reduces connectivity cost from €2.50 to €0.80/month per device for a 100,000-bird facility, with payback under 18 months via reduced mortality and feed waste.
Poultry Farm IoT Connectivity is the deployment of NB-IoT or LTE-M sensors to measure temperature, humidity, and air quality (NH₃, CO₂) inside poultry houses, managed via eSIM and a Connectivity Management Platform (CMP). For a 100,000-bird broiler facility with 200 sensors, switching from roaming physical SIMs to eSIM with remote provisioning cuts annual connectivity spend by €4,080 (from €6,000 to €1,920) and reduces sensor deployment time by 3 weeks per site.
WHY IT MATTERS
EU Directive 98/58/EC and national animal welfare codes now require continuous ambient monitoring in poultry houses—temperature must stay within 18–24°C, humidity 50–70%, and ammonia below 20 ppm. Before eSIM, each sensor needed a local SIM with separate carrier contracts for each country; per-SIM roaming charges averaged €2.50/month. With eSIM and a CMP using GSMA SGP.32 for remote profile switching, a single global IoT SIM plan covers all 200 sensors at €0.80/month per device. The CMP enforces per-sensor data cap of 5 MB/month, avoiding overage costs that used to add 15–20% to monthly bills. Cross-border profile switching via the CMP API eliminates site visits for SIM swaps when moving equipment between barns or countries.
TYPICAL APPLICATIONS
Broiler House Climate Control
In and out barns spanning 10,000 to 100,000 birds, temperature/humidity sensors report every 15 minutes via NB-IoT. A Global IoT SIM with eSIM profile for carrier A (local) and carrier B (roaming backup) ensures >99% uptime. Integrating the CMP RESTful API with the farm’s SCADA system triggers ventilation fans automatically when NH₃ exceeds 15 ppm. Catalog pricing covers 200 sensors; project quote needed when adding CO₂ sensors with higher data rate (LTE-M, 1-minute reporting).
Hatchery Multi-Country Deployment
For a hatchery group with sites in the Netherlands, Poland, and Spain, eSIM remote provisioning gives each sensor a local profile per country, avoiding roaming charges. The CMP dashboard shows live location and signal strength for all 500 sensors. Connectivity is managed under a single contract with volume pricing of €0.65/device/month for 500+ units. API integration with the hatchery’s ERP reduces manual SIM activation from 4 hours per site to near-zero.
Layer Barn Air Quality Alerts
In enclosed layer barns where ammonia can spike quickly, LTE-M sensors with eSIM send air quality data every 60 seconds. The CMP’s API can push alerts to SMS or cloud. For 50 sensors, catalog pricing is sufficient; for 150+ sensors with custom APN and private network (required by some integrators for low latency), a project quote is needed.

SELECTION NOTES
When your sensors report less than once per minute and are deployed in a single country with 500 or fewer devices, choose NB-IoT with a Global IoT SIM on catalog pricing (€0.80–€1.20/device/month). When you need sub-minute alerts for air quality or plan multi-country rollouts, select LTE-M with eSIM remote provisioning; require a project quote if the number of devices exceeds 500, if you need a dedicated APN for security compliance, or if the deployment spans more than three countries with different carrier preferences. Catalog pricing is sufficient when you can accept shared APN, standard SLA of 99.5% uptime, and no hardware customization. Project quote is mandatory for custom data plans (e.g., 10 MB/month per sensor), private network slices, or integration with proprietary farm management platforms that require the CMP API to expose real-time provisioning endpoints.
COST MODEL / TCO
Hardware Costs
NB-IoT sensor module (with sensors T/H/AQ): €25 per unit at 200 units = €5,000. External antenna (optional for deep barns): €3.50 each = €700. Total hardware: €5,700.
Connectivity Costs
Monthly per-device cost: €0.80 (eSIM, catalog pricing, 5 MB plan). Annual connectivity: 200 × €0.80 × 12 = €1,920. Overage buffer: leave 20% headroom = €2,304/year. Previous roaming SIM cost: €2.50/device/month = €6,000/year. Savings: €3,696/year.
Platform Costs
CMP platform (standard tier): €200/month for up to 500 devices = €2,400/year. This includes SIM lifecycle management, remote profile switching, and basic API access. Premium tier with advanced API analytics (€400/month) not needed unless >1,000 devices.
Installation & Maintenance
Installation: €10 per sensor (mounting, configuring) = €2,000 one-time. Maintenance: €5/device/year = €1,000/year (battery replacement, firmware OTA via CMP).
Total First-Year TCO
Hardware (€5,700) + Installation (€2,000) + Connectivity (€2,304) + Platform (€2,400) + Maintenance (€1,000) = €13,404. Compared to roaming SIM solution: €5,700 + €2,000 + €6,000 + €2,400 + €1,000 = €17,100. Savings of €3,696 in year 1, increasing each year as hardware depreciates. Payback: 18 months based on reduced mortality of 2% in a 100,000-bird flock (€8,000 value) and feed savings from optimized ventilation (€4,000/year).
When is catalog pricing enough?
Catalog pricing covers standard NB-IoT plans up to 500 devices in a single country, shared APN, and 5 MB/month data cap. If your pilot or production deployment fits that, you can order online with a credit card.
When must this go to project quote?
A project quote is required for multi-country deployments (e.g., hatcheries in 3+ countries), dedicated APN with fixed IP addresses, custom data volumes (e.g., 20 MB/month due to video), or any volume above 500 devices. Also if you need the CMP API integrated with your existing ERP via real-time provisioning endpoints – that typically involves a 2-week scoping engagement before quoting.
