four zones · each silo measured.
A grain silo has four fronts: internal conditions (humidity + internal temperature), ventilation + extraction (active control), level + inventory reconciliation, perimeter + security. AstreaIoT replicates the pattern per silo.
internal conditions
Temperature + ambient humidity + internal submersible temperature probe (at depth) per silo. Early detection of heat hotspots (compaction + fungal activity). Humidity >14% = immediate alert + ventilation activation.
ventilation + extraction
current meter on fans + extractors. Automatic ventilation control by humidity + temperature. Detection of fan failure before aflatoxins develop. Predictive motor maintenance.
level + reconciliation
Ultrasonic level sensor in each silo · continuous inventory. Reconciliation with inflows/outflows for theft or silent-loss detection. Reorder + sale scheduled with precise data.
perimeter + access
Nighttime PIR perimeter sensor + door sensor on load/unload hatches + LoRaWAN GPS tracker on critical equipment (trucks, tractors, forklifts). Anti-theft + access traceability for audit.
Out of scope: laboratory chemical analysis of aflatoxins (ELISA or HPLC). AstreaIoT PREVENTS development by monitoring conditions that favor aflatoxins — humidity >14% + temperature 25-35 °C are the triggers. Confirmation analysis remains lab.
what we protect · what we prevent.
- +Aflatoxins prevented with continuously monitored humidity + temperature
- +Threshold-activated automatic ventilation · fan with predictive maintenance
- +Continuous precise inventory · inflows/outflows reconciliation with data
- +Watched perimeter + equipment GPS · anti-theft and traceability
- +NOM-188 + SAGARPA + COFEPRIS audit backed with data
- ✕Hundreds of thousands of pesos per silo lost to visually-detected aflatoxins (already too late)
- ✕Cows or cattle sick from contaminated grain · significant secondary loss
- ✕Fan failing without alert · favorable conditions for fungus
- ✕Inventory without monitored level · silent theft · accumulated loss
- ✕Grain or equipment theft · rustlers + rural crime
eight use cases · four critical areas.
for the warehouse manager.
Warehouse Manager + Quality Lead. Two cases · humidity >14% initiates aflatoxins, hotspot from compaction. Prevention with early detection.
for the maintenance lead.
Maintenance Lead + Operator. Two cases · fan with intermittent failure, extractor overheating. Data-driven maintenance.
for the inventory lead.
Inventory Lead + Warehouse CFO. Two cases · visual-estimation inventory with errors, silent loss without reconciliation. Continuous precise inventory.
for the security lead.
Security Lead + Operations Director. Two cases · uncovered nighttime perimeter, critical equipment without GPS. Anti-rustling and theft coverage.
three compliances · one platform covers all three.
For multi-silo operators (Sinaloa, Tamaulipas cooperatives), cross-silo dashboard with per-silo condition + aflatoxin-risk ranking.
from sensor to report · every five minutes · without human intervention
Five steps. They run in parallel across all your sites, all the time. When something crosses a threshold, the flow completes in under five minutes — alert delivered, response logged, inspector-ready evidence captured.
measure
Sensors measure temperature, humidity, current, door-open, leak and other magnitudes every five minutes — no operator required.
detect
The system compares each reading against the threshold configured per recipe · per site · per equipment. Threshold crossing triggers the flow.
alert
The alert routes to the right person via WhatsApp, email or push · per role and schedule configured.
respond
The operator acts from the dashboard or mobile app. The corrective action goes into an immutable log with timestamp + signature.
audit
Everything becomes part of the audit package · time series, critical events, corrective actions, NOM report ready in two clicks.
Five steps · no manual operators · no paperwork · no gaps.
five phases · per silo.
site survey
1 dayTechnical visit + inventory of silos, fans, hatches, critical equipment · per-silo deployment plan.
physical installation
2-3 daysPer-silo humidity + ambient temperature + internal submersible temperature probe · current meter on fans · ultrasonic level · PIR perimeter + hatch door sensor · equipment LoRaWAN GPS tracker · gateway with 32-hour backup.
configuration + calibration
1 dayNOM-188 thresholds (humidity <14%, temperature <25-35 °C) · automatic ventilation control · WhatsApp alerts · COFEPRIS/SAGARPA/FDA report templates.
team training
1 dayWarehouse Manager + Quality Lead + Maintenance + Inventory + Security · each role trains on their flow.

For multi-silo operators (5-30 silos), per-site deployment with monthly waves · time-to-first-report 30-45 days per site.
common questions · before the quote.
does AstreaIoT detect aflatoxins directly?
No · AstreaIoT PREVENTS aflatoxin development by monitoring favorable conditions (humidity >14% + temperature 25-35 °C). Lab chemical detection of aflatoxins (ELISA or HPLC) is still necessary for confirmation. AstreaIoT is prevention, not chemical detection.
is the internal submersible temperature probe mounted without operational halt?
Yes · cabled probe inserts via top hatch of silo · reaches desired depth (typically 1/3 of silo height) · without interrupting operation. Sensor wired to external structure.
does it integrate with warehouse management system (SAP, Oracle, Microsip)?
Yes · via Custom Integration. Level + conditions + ventilation data arrives at central system. Reconciliation with ERP-recorded inflows/outflows.
what about silos in zones without internet?
Gateway with cellular backhaul or solar for remote silos. Compatible with warehouses in rural zones without own Ethernet.
does the humidity sensor work in silos with grain dust?
Yes · industrial sensor with IP65 dust protection. Initial calibration + recalibration every 12 months to maintain accuracy. Compatible with corn, sorghum, wheat, soy, barley dust.
is it billed per silo or per warehouse?
Flexible model · subscription per silo (typically 1 sensor cluster per silo) or per full warehouse (multi-silo cooperatives). Tiered pricing per number of silos + service tier.
is the FDA/USDA audit report pre-formatted?
Yes · pre-configured templates for FDA + USDA + COFEPRIS + SAGARPA. Downloadable PDF with immutable timestamp · aflatoxin-prevention evidence and documented conditions.
