Humidity Data Logger

A humidity data logger is a device that measures relative humidity (%RH) continuously and saves every reading digitally. That gives you a full moisture history for a room or process. The logger not only shows what the humidity is right now, but what it was at every point over days, weeks, or months.

A hygrometer shows you a live reading, the same way a thermometer shows live temperature. The AIOTHUB Humidity Data Logger does that too, but it also records and stores every reading with a timestamp, sends alerts when levels go out of range, and keeps a complete history you can see for an audit.

The Single-Channel Humidity Data Logger starts at ₹12,000. Multi-channel versions (up to 8 channels) are quoted based on how many points and features (4G, protocols, etc.) your site needs. WhatsApp us or request a quote, and we'll confirm pricing for your setup.

It covers the full 0-100% RH range with ±1.5% RH accuracy and very low long-term drift (under 0.25% RH per year), so it stays accurate for a long time without needing frequent recalibration.

Dew point is the temperature at which air becomes saturated and starts releasing moisture as condensation. The logger calculates it automatically from your RH and temperature readings, so you can spot condensation risk on cold surfaces, ceilings, or product before it actually happens.

No. The logger keeps recording on an SD card even without internet, and auto-uploads everything once the connection returns. A battery backup of 48-120 hours keeps it logging through power cuts too.

You set safe high and low RH limits for each area. When a reading crosses that limit, you get an instant alert by SMS, email, or WhatsApp, plus a local buzzer and LED. So you can act before mold, corrosion, or product loss.

Yes. Every reading is protected with AES-256 encryption and checksums that flag any change, so the logs hold up as trustworthy evidence during an inspection.

Yes. Combined with the AIOTHUB cloud portal, it gives you tamper-evident, time-stamped records, user access control, and secure time sync. It is built to satisfy HACCP, ISO 22000, and FDA 21 CFR Part 11 / GxP audits.

Yes, every unit can be supplied with an NABL-traceable calibration certificate, with scheduled re-calibration available so your compliance records stay valid year after year.

If you're monitoring one critical area, the single-channel logger (from ₹12,000) is the simpler choice. If you need to track humidity across multiple rooms or zones from one system, the multi-channel version (up to 8 channels) is the better fit.

Yes. It comes in an IP65-rated enclosure that resists dust and water, and it's built to keep working reliably in the high-humidity, condensation-prone environments it's designed to monitor.
