HiQ eSystems® Storm Remote Environmental Sensor for Humidity and Temperature

It is imperative that food, medicine, and other perishable items are stored in properly regulated environments including appropriate storage temperatures and humidity levels. Storm is a resilient and reliable sensor designed for rugged use environments. When tested on multiple 4-foot vertical drops onto bare concrete, the device survived without any loss of functionality. Storm is readily equipped to help manage your temperature and humidity needs across any industry.




Three-year warranty and up-to-five-year battery life. The typical 5+ year battery life of the HiQ eSystems in battery saver configuration provides reliable, hassle-free operation. Battery life under various conditions is specified as follows:

Battery LifeConfigurationDescription
3+ years*4 Low Data*2 60 minute Sample Collection Rate (SR) period with 60 minutes between Transmissions (TX) Data Storage Capacity (DC) of up to a year of data storage with our Glacier Series Sensors with data collection at this rate.
2.5+ years*4 Standard Configuration*1 10 min. SR, 30 min. TX
2+ years*4 High Data*3 5 min. SR, 10 min. TX, 1 month DC
DEFAULT MODE: No TX retries and 6 hour periods between configurations/ACK TX.
LOW DATA MODE: No TX retries and 6 hour periods between configurations/ACK TX.
HIGH DATA MODE: One TX retries and 6 hour periods between configurations/ACK TX.
All life figures are typical calculated performance when operating at room temperature with good communications-66dbm or better signal strength. Operating at maximum operating temperature or without any communications can reduce battery life by as much as 50%.


Flexible external antenna and robust internal connections. HiQ eSystems is designed rugged for use in demanding environments; perfect for hypersensitive and extreme use applications. Manufactured in a moisture and contaminant free environment, there are no fragile internal parts, and no "screw-on" or "plug-in" connectors to penetrate the protective casing.

Range and Connectivity

HiQ eSystems features 900 Mhz* frequency technology, which, when compared to WiFi-enabled sensors, provides higher transmission power, faster communication, and lower transmission loss, all with greater customization options. (*900 Mhz frequency is not available in all countries.)

HiQ eSystems environmental humidity and temperature monitoring sensor systems provide best-in-class wireless range and connectivity. Incorporating proprietary networking protocols, HiQ eSystems sensors feature dense network operation (point-to-point, point-to-multi-point) and localized, corporate, or global roaming device configurations. All HiQ eSystems devices are remotely configurable.

HiQ eSystems radio technology supports wireless line-of-sight ranges of up to 28 miles at 10 Kbps and wireless line-of-sight ranges up to 4 miles at data rates of up to 200 Kbps, which makes HiQ eSensors sensor systems flexible enough for extended-range applications or high data rates. The network is easy to set-up and use. Data access and changes to functionality are controlled via four assignable management tiers.

Smart Data System

Monitoring storage and transportation environments is critical for the intelligent management and safety of your organization's perishable assets.

HiQ eSystems Smart Data provides:

  • Sampling of temperature data at user-configurable intervals
  • Storage and transmission of data according to customer-defined parameters
  • Custom alerts for out-of-spec environmental conditions
  • Increased data transmission rates when alarm or change conditions are exceeded
  • Allows for remote re-configuration of sensors
  • Data accessibility via customer's server, web page, PC, and mobile device
  • Press of a button remote upgrading of gateway firmware
  • Stores sample data during Power/LAN/Internet outages for subsequent transmission when services return
  • Up to two months storage capacity of temperature data sampled every ten minutes

Quality Assurance

HiQ eSystems feature Avatar, a safer and more reliable alternative to glycol product simulants, providing a record and traceable path, tracking sensitive inventories every step of the way, from transit to storage and final delivery. A commonplace physical sensor only measures the temperature of an individual glycol simulant package, which must be identical to, and packaged with, the product for best results. Inconvenience and fears of cross-contamination, however, often result improper setup and placement, leading to inaccurate readings. Avatars give an accurate reading of the entire shipment environment by mathematically modeling the temperatures of individual packages, using just one convenient sensor located outside the product. No messy simulant package required.

Storm Specs

Operating Range

-40°C to 60°C (-40°F to 140°F)
0% to 100% RH (non-condensing)

Temperature Accuracy*1

± 0.5°C (1.0°F)

Humidity Accuracy*2

± 5%

This high temperature accuracy is applicable within the operating range of -10°C to 60°C (15°F to 140°F). Below -10°C one can expect accuracy to drop to about ±1°C (2.0°F) at about -40°C/F.
This is with natural variation above and below 50% and non-condensing environments. Controlled environments much different from an average 50% RH can add additional measurement bias.
