Frequently Asked Questions

Quick answers to the most common questions. For product-specific FAQs (battery calibration, probe submersion, humidity limits), the sensor detail pages have full Q&A sections.

Getting started

How do I add a sensor to my account?

Scan the QR code on the back of the sensor, or add it by serial number in the iMatrix mobile app. Guest mode is also supported for quick tests.

What do I need to get started?

One Neo sensor and one Micro Gateway. Plug the gateway into any USB-powered device with Wi-Fi in range, pair the sensor via the mobile app, and you're tracking.

How often does the sensor take readings?

The reading cadence is adjustable in iMatrix Cloud — from seconds to once per day. More frequent readings shorten battery life.

Can I view past readings?

Yes. Every sensor logs continuously to iMatrix Cloud. Graphs, historical data, and signed PDF exports are available for audit purposes.

Sensors

How long does the battery last?

Standard Neo sensors: 3+ years (2× AAA lithium or 1200 mAh). Sentry-1: ~13 months on a CR2032. Neo-IND: up to 44 months.

What is the humidity limit?

0% to 100% RH. Accuracy decreases near 100%. For condensing environments, use the Neo-1P probe variant instead.

Can I fully submerge the sensor?

Only the Neo-1P external probe may be placed in liquids. Neo body units are IP66 (splash-proof, not submersible). The Neo-IND is IP68 and fully submersible.

What's the temperature range?

Ranges vary by model. Neo-1: -40°C to 70°C. Neo-1P probe: -40°C to 100°C. Neo-IND: -40°C to 85°C. Check the product page for exact specs.

NIST & Compliance

What does NIST certification include?

Multi-point NIST-traceable calibration at an ISO 17025-accredited lab. Signed certificate archived in iMatrix Cloud for the life of the device.

How often do I need to recalibrate?

Most regulated environments require annual recalibration. iMatrix recertification is $77.00 per sensor plus $9.99 shipping and handling per order, with an approximately 2-week round trip. Ship the sensor back and it returns with a fresh NIST-traceable certificate archived in iMatrix Cloud. Request a recalibration →

Are my audit exports HACCP-compliant?

Yes. iMatrix Cloud exports signed PDF reports with every reading, alert event, and sensor serial. FDA, USDA, and CDC audit teams accept them directly.

Can I replace a lost certificate?

Yes. Request a replacement from your account. Typically processed within one business day.

Gateways & Connectivity

Micro Gateway or Series-1?

Micro Gateway ($59.99) for small sites — up to ~50 sensors. Series-1 WiFi Mesh for hundreds to thousands of sensors across warehouses and multi-site deployments.

What if I lose Wi-Fi?

Sensors log up to 6 months of readings on-device. When the gateway reconnects, readings backfill to the cloud automatically — no data lost.

Can I use cellular instead of Wi-Fi?

Yes — but check which device carries the cellular radio. The Micro Gateway and Series-1 are Wi-Fi gateways with no cellular radio of their own. For one box that reads Neo sensors over BLE and backhauls over LTE, use the FC-101S-PRO or FC-501. Otherwise an EdgeUplink 4G hotspot or router supplies the Wi-Fi that a Micro Gateway or Series-1 sits on. Compare all gateways →

Do I need iMatrix Cloud?

Cloud access is included with every product — no separate subscription. API access and multi-user seats unlock at higher tiers.
