Cold Storage Temperature and Humidity Monitoring System will be a perfect solution for cold storage applications in which the temperature and humidity are critical parameters to be maintained at specified limits to store the packages in deep freezers and cold room facilities. Our solution comes with the external temperature and humidity sensor which has a measuring capacity of 0 to +50°C and 0 to 100% RH respectively. Generally, these external sensors are installed inside the cold storage rooms and the device will be mounted outside for easy access to the user.
Applications: Vaccine Storage Cold Rooms, Warehouses, Pharmaceuticals, Hospitals, IT Sectors, etc.

Cold Storage Temperature and Humidity Monitoring System is the most economical IoT solution which can be installed in cold storage facilities for measuring temperature and humidity. The device is basically plug and play device that does not require any additional installation and commissioning which makes this different from other solutions available on the market. The device has a standard feature through which the user can configure up to 5 different mobile numbers to receive SMS alerts with user-configurable time intervals. Users from remote locations can access and download the recorded data in various formats (Excel/CSV/PDF) through a centralized dashboard and can also configure 10 different email IDs for Email Alerts. The device has a large LCD backlight display which indicates the current measured parameter values with setpoint limits and along with the date and time stamp for user accessibility.
Features of Temperature and Humidity Monitoring system :

SMS Alert: 

  • Periodic SMS: SMS at regular time intervals programmable by the user.
  • Alert SMS: SMS on Temperature exceeding set limits (Lo & Hi).
  • On-Demand SMS: SMS on request from registered mobile numbers.

Note: Provision for registering up to 5 mobile numbers (Standard), Contact store for any other customization.
Email Alert :

  • Email Alert Notification when the parameter value is out of the pre-setting threshold.
  • Provision for registering multiple Email IDs(Standard 10 Email Ids can be configured) multiple Email IDs(10 Email Ids can be configured).

Cloud Function:

  • Web-Based software-independent Interface (Mobile/PC/Tab) to view real-time data transmitted through the device.
  • Dashboard to monitor real-time data with downloading, reporting in Excel/PDF Format, Custom Report designing as per user requirement also available.
