Temperature Monitoring Sensors Protect Your Fridge & Freezer Inventory 24/7
Never Lose Sleep Over a Broken Fridge or Freezer Again! Jolt sensors are an industrial strength solution using advanced technology and smart alerts for cold storage inventory protection and food safety.
What is a Temperature Sensor and Why Do You Need One?
A temperature sensor is a small, wireless device that constantly monitors the temperature. It automatically sends data to your phone or computer, so you can see the temperature(s) of your refrigerators, walk in coolers, and freezers from anywhere, at any time.
A Jolt sensor automates your food safety to protect customers and your reputation, have digital logs to make audits simple, and track long-term equipment health to prevent expensive, unexpected repairs. Eliminate hours of manual temperature checks, which simultaneously reduces labor costs.
How Do You Know Your Sensor Is Actually Working?
Jolt sensors are proactive—they don’t just monitor your freezer; they monitor themselves. You get an immediate alert for low batteries or a lost connection, so you’re never left guessing. Other sensors just die silently, leaving you guessing if they’re actually working.
Jolt’s sensors alone have already saved me thousands of dollars in product loss by catching a refrigeration unit whose daily temperature was slowly rising by sending me an alert before I lost all my refrigerated inventory.

Jolt’s sensors have made it possible for us to find the weak points in some of our coolers, and freezers. To where we were able to call it in, and have them fixed before we lost thousands of dollars in product.

Jolt: The Best Refrigerator & Freezer Temperature Monitor With Alarm
Jolt is an all-in-one monitoring system, not just another sensor with an alarm. We offer a combination of superior hardware and intelligent software—giving you peace of mind with actionable alerts, higher compliance, and inventory protection.
Monitor Cold Inventory
Advanced Tech
Smart Alerts
24/7 Temperature Monitoring From Anywhere
Whether you’re at home or on vacation, you get instant, actionable alerts via text or email the moment a real issue is detected. Check the live status of your sensor(s), right from the Jolt app on your phone or tablet.
Jolt goes further. Our system isn’t just a simple alarm; it’s a communication tool. Set custom escalation paths so a manager gets the first alert at 30 minutes, a regional director at 60, and the owner at 90. It’s customizable, you decide who knows what, and when.
This is what real monitoring control looks like: smarter notifications, and the power to prevent catastrophic loss from anywhere in the world.
Industrial-Strength Signal for Unbreakable Monitoring
The walk-in freezer is a dead zone for standard wireless signals. The thick metal walls and humming equipment are a kill zone for the crowded 2.4 GHz frequency used by WiFi and Bluetooth sensors. That’s why those “wireless” systems constantly drop their connection, leaving you with dangerous gaps in your data.
Jolt doesn’t use WiFi. We use LoRaWAN (Long Range Wide Area Network), the industrial-grade standard for long-range, low-power communication. A sensor that can easily monitor commercial grade fridge and freezers without running any wires.
This means you get an unbreakable signal even from your deepest freezer to a secure gateway tucked away in an office. No more dropped signals. No more missed alerts. It’s the difference between a gadget and a professional-grade tool.
We offer commercial-grade reliability, our sensors are designed for the tough environment of a commercial kitchen. With a long battery life and a strong wireless connection, you can trust Jolt to keep an eye on your cold inventory 24/7.
Get Smarter Alerts with Our Food Simulation Algorithm
Other sensors track ambient air. A door opens for a minute, cold air rushes out, and management gets a panic-inducing alert for a problem that doesn’t exist. False alerts can be a waste of time and creates a culture of ignored alerts—which is dangerous.
Our system understands the difference between a brief temperature swing such as a door opening and a real thermal threat to your inventory. Our temperature monitoring system tracks the product’s core temperature, not just the volatile air around it.
The result? In head-to-head tests, our sensors provides up to a 9-degree more accurate reading. You see what’s actually happening to your food, allowing you to avoid alert fatigue and act only when it really matters.
Monitor and Log All Food Safety Critical Control Points
Digital Log for Food Safety
Protect Your Customers
Hassle-free Audits

Stop Paying Your Team to Be Human Thermometers
How many hours a week do your employees spend walking around with a clipboard and a thermometer? That’s time they could be serving customers or prepping food. That’s labor you’re paying for that adds zero value to your guest experience.
Jolt puts an end to that.
Our sensors integrate directly with your Jolt digital checklists. When your manager starts their daily food safety line check, the temperatures from every single critical asset are already there, automatically populated and time-stamped. No more walking into freezers. No more writing on clipboards.
With a single tap, your team can verify an entire location’s temperature logs in seconds, not hours. You’re not just buying a sensor; you’re buying back your team’s time, reducing your labor costs, and ensuring your compliance logs are always accurate and ready for a health inspection.
Predict Equipment Failures Before They Happen
A temperature alert tells you about a problem that’s already happened. Save yourself from down equipment, Jolt’s historical data tells you about a problem that’s going to happen.
Your sensors are constantly collecting performance data on your most critical and expensive equipment. With Jolt’s powerful reporting dashboards, you can visualize see trends that are invisible day-to-day. You’re no longer just monitoring food safety; you’re tracking the health of your equipment.
See a walk-in freezer that’s slowly struggling to hold its temperature over several weeks? That’s a compressor failure waiting to happen. Notice a prep cooler’s temperature fluctuating more than it used to? That’s a sign its seals are starting to wear out.
This is the data that allows you to move from expensive, unexpected emergency repairs to being proactive with scheduled maintenance. Jolt transforms your sensors from a simple insurance policy into a predictive tool that saves you thousands in costly downtime and last-minute service calls.
What Current Customers Say…
Sensors have been a really nice feature for us. I love the peace of mind knowing that I will receive a text when the freezer is out of range for too long. I like being able to log in on my iPad at home, and see exactly where we are at, or I can log into my computer and see where the readings have been over the last 12 hours. They have been really great.
Christina H. Tropical Smoothie Cafe
Jolt Sensors alone have won my business. They saved my inventory this past week. I probably had $4,000 of product in my freezers and coolers that I would have lost without your sensors!
Dalton E. Sabor Latin Street Grill
Right after we installed Jolt Sensors we found out that we had a problem with one of our doors. The seal wasn’t sealing correctly, and to be honest, I don’t think we would have noticed had we not had those sensors in there. So we could have lost $3,000 worth of chicken if we hadn’t caught it. So from day one, it made a difference.
