Need hardware recommendations for this problem?
Send the measured signals, alarm rules, site power and communication constraints. We will return a hardware configuration for quotation.
Problem to solve
A cold room can drift outside its allowed range before staff notice. Monitoring must record temperature, door events and alarm timing clearly.
Measurements that matter
- Temperature and humidity
- Door open status
- Power failure or offline state
- Alarm duration and timestamp
Suggested hardware configuration
- Temperature humidity sensor
- Door or power status input
- LoRaWAN, NB-IoT or 4G gateway
- Alarm routing to customer workflow
Typical Hardware Architecture
Final system design, software integration, PLC/SCADA programming and site installation are handled by the customer or their system integrator.
Customer system
Customer's SCADA / Cloud / PLC System
Information needed before quotation
- Temperature range and accuracy
- Room count and wall material
- Alarm recipients
- Calibration or certificate expectation
Recommended next steps

FAQ
What does SunGene need before quoting Cold Room Temperature Excursion?
Please provide temperature range and accuracy, room count and wall material, alarm recipients, calibration or certificate expectation. These inputs determine the sensor, gateway, power and integration path.
Is this a software-only service?
No. SunGene supplies sensors, gateways, field connectivity hardware and documented data-handoff interfaces for the buyer or integrator. Software-platform configuration and operation are outside the standard hardware scope.
Can SunGene support custom configuration if needed?
Yes, after the hardware configuration, certificates, sample quantity and documentation scope are clear.
Which technologies are usually considered?
The typical shortlist includes Temperature, Humidity, LoRaWAN, NB-IoT, 4G LTE. Final selection depends on site constraints and target country requirements.
