The compact sensor runs on 2 AA batteries which provide a battery life of up to 12 months. Made in the USA, the Temp Stick is an accurate and reliable WiFi freezer alarm that will allow you to monitor your freezer’s temperature level from anywhere. Best Overall: Temp Stick WiFi Temperature & Humidity Sensor To help you find the best freezer monitoring system for your home or commercial freezer, we’ve put together a list of the highest-rated freezer alarms on the market.

With LoRa-based temperature sensors, TNPRC was able to achieve stronger wireless communication with just two gateways throughout its multi-building campus. Using this technology to back our state-of-the-art system, we can assure our customers get the real-time temperature data they need, with fewer concerns about reliability, ease of installation or other vulnerabilities.Ĭonsider the real-world case where Tulane University’s National Primate Research Center (TNPRC) needed to accurately and consistently monitor internal temperatures in hundreds of freezers across all 22 buildings of the TNPRC campus. Recognizing the challenges of Wi-Fi-enabled remote temperature monitoring systems, the CORIS team saw an opportunity to leverage the power of LoRa as an alternative. CORIS Enables Remote Temperature Monitoring Without Wi-Fi With enhanced security measures built into its architecture - including end-to-end encryption and enhanced network visibility - LoRa communications are virtually impossible to be intercepted by an unauthorized user. For instance, if the freezers or refrigerators you want to monitor are in campus buildings across the street from each other, you may be able to monitor them all with one gateway.įrom a security standpoint, LoRa also greatly surpasses Wi-Fi. Albeit with some limits, LoRa wireless signals can penetrate concrete and cinder block walls and floors - usually about 20 or 30 walls and three to five floors, depending on building construction.Ĭonsidering their reliability, LoRa wireless signals even have the power to travel between buildings with only a single gateway required to enable communications - which, for you, means faster installation times and lower costs. To put this in perspective, LoRa wireless signals can travel 10 miles outdoors with no obstructions. Where Wi-Fi struggles with sustained reliability, LoRa succeeds. Short for long range, LoRa is designed specifically to form long-distance communication links via IoT and machine-to-machine applications. If you’re wondering what LoRa stands out for, the name is a nod to the benefits of this wireless communication technology. Trading in Wi-Fi-Enabled Temperature Sensors for LoRa-Enabled Sensors Is there an alternative, and does it effectively address the issues noted above? In the case of LoRa wireless technology, the answer is yes. With these issues top of mind, it raises the question of how to monitor temperature remotely without Wi-Fi. Wi-Fi is inherently susceptible to hacking that can expose private, sensitive data.When Wi-Fi connections go out, the sensor often has to be re-initiated to re-establish a connection.Wi-Fi has difficulty penetrating the walls and floors of buildings, especially large-scale buildings.But a Wi-Fi connection itself presents innate challenges. On paper, this route seems convenient as it enables personnel to monitor temperature from any location with an existing Wi-Fi hotspot. That’s to say the temperature data the sensor collects is transmitted to the cloud by way of a local Wi-Fi hotspot near the sensor. Many of the temperature sensors that are deployed across industries are Wi-Fi-enabled.
