Multi-Probe Sensors
Each monitoring unit supports several temperature probes so a multi-zone reefer or a large cold room can be measured at multiple points, not just one.
- Up to 4+ probes per unit
- Independent zone readings
- Calibrated ±0.5°C accuracy
The sensor and alerting layer behind every cold chain — multi-probe temperature and humidity monitoring with real-time SMS and app alerts and tamper-evident data logging for reefers, warehouses, cold rooms and pharma fridges across Pakistan.
By the Numbers
Manual logbooks and a thermometer on the wall miss the excursions that actually cost you. Continuous sensors with automatic alerts catch them the moment they start.
Capabilities
Multi-probe hardware, threshold logic and cloud logging that you can deploy on a single fridge or scale across an entire warehouse network.
Each monitoring unit supports several temperature probes so a multi-zone reefer or a large cold room can be measured at multiple points, not just one.
Combined temperature and relative-humidity sensing protects products like medicines, produce and electronics where moisture matters as much as heat.
Set high and low limits per probe and get an instant SMS, app and email alert the moment a reading drifts out of the safe band.
Every reading is time-stamped and stored, so you can replay any period, export records and prove a fridge or reefer stayed in-spec.
Optional power-failure and door-open inputs explain why a temperature moved — a tripped genset or a door left open — not just that it did.
Built-in 4G LTE with 3G/2G fallback keeps sensors reporting across Pakistan's networks, with on-device storage during any signal gap.
How It Works
A simple four-step path from a raw sensor reading to a documented, alert-driven monitoring system.
We position calibrated temperature (and optional humidity) probes at the points that matter — cargo space, each cold-room zone, or inside a pharma fridge — wired to a single monitoring unit.
For every probe you set a high and low limit and the people who should be alerted. A 2–8°C fridge, a −18°C freezer and a humidity-sensitive store can each have their own rules.
Readings flow to the dashboard over 4G. The instant a probe breaches its limit, IOTee fires an SMS, app push and email — including which sensor, the value and the time — so someone can respond fast.
All readings are stored for 365 days. View trend charts, replay any period and export PDF or Excel records whenever quality, a customer or an audit needs proof.
Where It's Used
One monitoring platform that adapts to moving reefers, fixed cold rooms, pharma fridges and ambient warehouses.
Drop probes into refrigerated trucks and delivery vans to log the cargo compartment temperature continuously, the foundation of a monitored cold chain.
Monitor ambient warehouses, chillers and blast freezers at multiple points, with power-failure alerts that flag a cooling outage instantly.
Keep medicine fridges, vaccine refrigerators and lab freezers continuously logged with tamper-evident records for quality and audit.
Watch chillers, freezers and prep areas in hotels, restaurants and central kitchens so food-safety limits are met and documented.
Track temperature and humidity in greenhouses, grain stores and produce holding areas to protect yield and reduce post-harvest loss.
Protect IT rooms, telecom shelters and sensitive equipment with temperature and humidity alerts before overheating causes downtime.
A temperature monitoring system is sensor hardware plus software that continuously measures temperature (and often humidity) at one or more points and automatically alerts you when a reading goes outside a safe range. IOTee's system in Pakistan uses calibrated multi-probe units that you place inside reefer trucks, cold rooms, pharma fridges or warehouses. Each probe reports to a cloud dashboard over 4G, you set high and low thresholds per probe, and the moment a limit is breached the system sends an SMS, app and email alert. Every reading is logged for 365 days so you can chart trends, replay any period and export records for audit. It is the underlying sensor and alerting layer that powers a full cold chain.
The temperature monitoring system is the hardware and software building block — multi-probe temperature and humidity sensors, threshold logic and data logging — that you can deploy on a single fridge, a cold room or a reefer on its own. Cold chain monitoring is the complete end-to-end solution built on top of it: it ties that sensor data to GPS routes, door events, last-mile delivery and audit-ready, regulator-facing compliance reporting across pharma, vaccines, dairy and frozen food. If you need standalone monitoring for specific assets, this page is the right fit; if you need full logistics-and-compliance coverage of an entire chain, see our cold chain monitoring service.
Each IOTee monitoring unit supports multiple probes — typically four or more — so a multi-zone reefer or a large cold room can be measured at several points instead of relying on a single reading. Probes can measure temperature alone or combined temperature and relative humidity, which matters for medicines, fresh produce, electronics and server rooms where moisture is a risk. Each probe has its own high and low thresholds and its own alert recipients, and a single dashboard shows every probe across every site, so you can manage a fridge, a freezer and an ambient store from one screen.
IOTee's temperature probes hold roughly ±0.5°C accuracy, which is suitable for both pharma-grade (2–8°C medicine fridges, vaccine storage) and food-grade (chilled and −18°C frozen) monitoring. Probes are calibrated before deployment and can be re-checked on a schedule so your records stay defensible. Because every reading is time-stamped and stored, you always have an objective, tamper-evident history rather than relying on someone remembering to write down a number — which is exactly what quality teams and auditors want to see.
Alerts are delivered within about 60 seconds of a reading crossing a configured limit, over three channels at once: SMS to Pakistani mobile numbers, mobile-app push notifications and email. Each alert names the sensor, the value and the time so the recipient knows exactly what to check. You can assign different recipients to different probes and set escalation, so if an excursion is not acknowledged it moves up to a supervisor. You can also set mute windows for planned events like a scheduled defrost so you are not flooded with expected alerts.
Yes. The units use 4G LTE with 3G/2G fallback to stay connected across Pakistan's networks, and they buffer readings on the device during any signal gap, syncing them to the cloud once connectivity returns — so your log stays complete. An optional battery backup keeps the sensor running through a power cut, and a power-failure input can itself raise an alert so you know the moment a cold room loses mains power. This is important in Pakistan, where load-shedding and outages are a frequent cause of temperature excursions.
Absolutely. While the system is ideal for reefer trucks, it is equally suited to fixed sites: ambient warehouses, walk-in chillers, blast freezers, pharma and vaccine fridges, lab freezers, hotel and restaurant kitchens, greenhouses, grain stores and even server or telecom equipment rooms. Any place where temperature or humidity needs to stay within a band and you need proof it did. The same multi-probe units, threshold alerts and 365-day logging apply across all of them, managed from one dashboard regardless of how many sites or assets you run.
Sensor hardware generally falls in the Rs 8,000–15,000 per-unit range, depending on the number of probes and whether humidity, door and power inputs are added. The cloud monitoring, alerting and data-logging software is billed per asset, typically around Rs 300–800 per unit per month. Exact pricing depends on how many probes and sites you have and the depth of reporting you need. IOTee provides a free assessment and a written quote, and there is no extra charge based on how many threshold alerts or exported reports you generate.
