four zones · bodies protected · families respected.
A funeraria has four operational fronts where medical-legal integrity and family dignity are made or broken: preservation cold rooms, chain-of-custody legal access, operational continuity (critical generator) + embalming IAQ + controlled chemicals, viewing rooms + chapels. AstreaIoT covers all four with the same platform.
preservation cold rooms -10 to -20°C
temperature probe per preservation cold room + door sensor + compressor current meter with cycle analysis. Early detection of refrigeration degradation before it affects bodies in custody. Automated report for medical-legal integrity.
chain-of-custody · auditable access
door sensor with timestamp on every access to preservation + embalming room + legal archive. Immutable log of who/when · audit trail for criminal investigation when applicable. LFPDPPP compliance for sensitive family data.
backup generator + embalming IAQ + formaldehyde
backup generator current meter + diesel level sensor + automated weekly validation (max criticality — generator CANNOT fail). Multi-parameter IAQ sensor in embalming room. **Formaldehyde detection via 9-in-1 air-quality sensor (direct-import 4-8 weeks) — includes HCHO + O₃ + PM10 + standard IAQ. Alternative via industrial HCHO transmitter + RS485-LB Modbus bridge for immediate deployments.**
viewing rooms + chapels + records
HVAC thermostat per viewing room + chapel (family comfort during hours-long wakes). PIR occupancy sensor. Server room for records with T+RH probe + leak sensor. Leak sensor under critical zones (laundry, embalming).
Out of scope: specific medical-forensic equipment (embalming table, autopsy) — under manufacturer maintenance. Also no in-viewing-room or consult-room recording (absolute family privacy).
what we protect · what we prevent.
- +Bodies in custody preserved · absolute medical-legal integrity · family lawsuits avoided
- +Documented chain-of-custody · immutable audit trail · criminal investigation backed
- +Generator always ready · zero blackouts affecting preservation · absolute operational continuity
- +Embalming IAQ + controlled formaldehyde (via multi-gas air-quality sensor) · protected staff · STPS compliant
- +Viewing rooms + chapels with comfort · families served with dignity
- ✕Overnight refrigeration fails · body in legal custody compromised · family lawsuit millions of pesos
- ✕Undocumented access to embalming room · chain-of-custody compromised · investigation blocked
- ✕Backup generator fails at CFE blackout · critical refrigeration loss · irreversible damage
- ✕Unmonitored formaldehyde in embalming room · staff with chronic respiratory risk · STPS observation
- ✕Viewing room with failed HVAC · uncomfortable families during wake · funeraria reputation damaged
eight use cases · four critical areas.
for the medical-legal lead + funerary director.
Medical-Legal Lead + Funerary Director + Embalming Lead. Two cases · preservation cold room with overnight failure (bodies in custody), compressor with gradual degradation (failure imminent). Absolute medical-legal integrity.
for the funerary director + legal lead.
Funerary Director + Legal Lead + Internal Auditor. Two cases · undocumented access to embalming room, legal archive with unauthorized opening. Immutable audit trail.
for the embalming lead + maintenance.
Embalming Lead + Maintenance + Sanitary Lead. Two cases · backup generator doesn't start at CFE blackout, formaldehyde accumulating in embalming room. Staff and operation protected.
for the administrative director + GM.
Administrative Director + GM + Service Coordinator. Two cases · viewing room with failed HVAC during hours-long wake, server room with critical records without thermal protection. Dignity + records.
three compliances · one platform covers all three.
For multi-property funerary chains (Gayosso-style), cross-funeraria dashboard with compliance ranking + efficiency + standardized audits. Multi-gas air-quality sensor direct-import available for cross-property deployment once procured.
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 funeraria.
site survey
1-2 daysTechnical visit + inventory of preservation cold rooms, critical access, embalming room, generator, viewing rooms, chapels, server room · deployment plan + identification of air-quality sensor procurement timing.
physical installation
3-5 daysT probes per cold room + door sensors + embalming IAQ sensor + generator meters + thermostats per viewing room · gateway with 32-hour backup · without interrupting funerary services (installation between wakes).
configuration + LFPDPPP integration
2-3 daysCOFEPRIS + NOM-016-SSA3 + LFPDPPP thresholds · calibrated probes · WhatsApp alerts per role · chain-of-custody templates · audit trail configured.
team training
1-2 daysFunerary Director + Medical-Legal Lead + Embalming Lead + Legal Lead + Maintenance + GM · each role trains on their flow + cross-funeraria dashboard onboarding if applicable.
30 days of support + first audit + multi-gas sensor deployment
30 days + multi-gas sensor direct-import lead time (parallel)AstreaIoT specialist available · first monthly COFEPRIS report delivered · first backed legal audit-trail · formaldehyde sensor installed when it arrives (4-8 weeks direct-import + codec validation).
For multi-property funerary chains, wave-based deployment with standardized BOM + consolidated multi-gas sensor procurement for all properties simultaneously.
common questions · before the quote.
when is the formaldehyde sensor available?
The 9-in-1 air-quality sensor (includes HCHO + O₃ + PM10 + standard IAQ) is direct-import with 4-8 week lead time + ChirpStack codec validation. For immediate deployment without waiting for the multi-gas sensor, we offer an industrial HCHO transmitter + RS485-LB Modbus bridge — slightly higher BOM but immediately deliverable. Let's discuss which path you prefer in the quote.
is family privacy absolutely respected?
Yes · zero cameras + zero audio in viewing, embalming, consult rooms. Only environmental sensors (T+RH+CO₂+formaldehyde) + door sensors + PIR presence (no image). Family data complies with full LFPDPPP.
is the chain-of-custody audit trail legally admissible?
Yes · immutable log with cryptographic timestamp + documented access record · admissible as auxiliary evidence in medical-legal investigation. Compatible with Ministerio Público + state procuradurías requirements.
what about prolonged CFE blackouts in remote properties?
Gateway with cellular or solar backhaul + local 32-hour buffer. Monitored backup generator for pre-blackout validation. Critical refrigeration must never interrupt — predictive alert to maintenance.
does it integrate with existing funerary management system?
Yes · via Custom Integration L3. Compatible with common Mexican funerary systems · cold chain + chain-of-custody + IAQ data feeds the central system · billing + audit from single dashboard.
is pricing per funeraria or per chain?
Flexible model · per-funeraria subscription with tier per number of cold rooms + viewing rooms + locations. For multi-property chains (Gayosso-style), discount per number of funerarias + cross-property dashboard included. Consolidated air-quality sensor procurement for chains.
does it integrate with Ministerio Público investigation?
Yes · immutable chain-of-custody audit trail deliverable as auxiliary evidence. Pre-formatted legal report with door sensors + hour-based access · meets state procuradurías and federal Ministerio Público requirements.
