What is an industrial humidity data logger?
An industrial humidity data logger records relative humidity (%RH) and ambient temperature over time, storing every reading with a cryptographically verified timestamp.
The AIOTHUB logger adds what industrial sites need on top: alerts the moment moisture levels cross your safe limits, local SD buffering that prevents data gaps during network outages, and Modbus/MQTT for immediate SCADA or BMS integration.
It is the most dependable, low-cost way to maintain cleanroom stability, prevent mold and corrosion, and pass GMP/ISO regulatory audits.

From pharma cleanrooms to cold warehouses, the Humidity Data Logger keeps your records complete and your team notified.
Audit-ready compliance data
Tamper-evident, time-stamped records built for FDA 21 CFR Part 11, HACCP, and ISO 14644 quality standards.
Real-time alerts, zero downtime

How to Choose the Right Humidity Data Logger
Six factors separate a logger that safely protects your humidity systems from one that fails during audit reviews.
Sensor accuracy & drift
Ensure the logger offers ±1.5% RH accuracy and annual drift below 0.25% RH for long-term consistency without frequent recalibration.
Dew point calculation
Verify if the logger automatically calculates dew point to anticipate condensation risks before water droplets ruin sensitive products.
Connectivity & alerting
Select units with Wi-Fi, 4G, or Ethernet to push real-time excursion alerts instantly via SMS, WhatsApp, and email.
Memory & battery backup
Confirm internal SD buffering and rechargeable lithium battery backup so power outages cause zero gaps in your humidity audit logs.
Compliance & audit readiness
Choose systems supporting FDA 21 CFR Part 11, GxP, and NABL traceability with automated tamper-proof PDF generation.
Enclosure & probe protection
Select IP65 enclosures with sintered PTFE or stainless filter caps for cleanrooms or high-moisture condensating environments.

Humidity Data Logger FAQs
The questions engineers, cleanroom managers, and purchase teams ask us most before ordering.
A humidity data logger automatically measures and records relative humidity (%RH) and ambient temperature continuously over time. It gives you a time-stamped history of moisture changes, helping you protect sensitive products, prevent mold and corrosion, and maintain regulatory compliance.
A hygrometer only displays the current live reading. The AIOTHUB Humidity Data Logger records and stores every reading digitally with a timestamp, triggers instant alerts on excursions, and provides tamper-proof historical logs for quality audits.
It covers 0 to 100% RH with ±1.5% RH accuracy and annual drift under 0.25% RH, ensuring long-term measurement precision without frequent recalibration.
Dew point is the temperature at which air becomes saturated and moisture condenses. The logger automatically calculates dew point from %RH and temperature, alerting you before condensation forms on cold surfaces, ceilings, or equipment.
The logger continues recording seamlessly on an industrial SD card. An internal rechargeable lithium battery provides 48 to 120 hours of backup, automatically syncing data to the cloud once power and connectivity return.
You can configure safe high and low %RH thresholds. When an excursion occurs, instant alerts are dispatched via SMS, email, WhatsApp, and the onboard audio buzzer.
Yes. Every record is protected with AES-256 encryption and cryptographic SHA256 checksums that flag any unauthorized modification, ensuring the records hold up during inspections.
Yes. Combined with the AIOTHUB cloud platform, it provides tamper-evident time-stamped electronic records, user access control, and automated compliance summaries meeting USFDA 21 CFR Part 11, HACCP, and ISO 14644.
Yes. Every unit can be supplied with an NABL-traceable 2-point and 3-point calibration certificate for relative humidity and temperature.
Yes. It supports Modbus RTU (RS485), Modbus TCP, MQTT, and OPC-UA, allowing seamless integration into existing PLC, SCADA, and building automation systems.
Yes. Built in an IP65-rated polycarbonate enclosure with sintered PTFE filter caps, the unit resists dust, water sprays, and high condensation.
The AIOTHUB single-channel Humidity Data Logger starts from ₹12,000 for standard %RH+Temperature configurations. Multi-channel configurations are quoted based on probe count and wireless options.
