yieryi RC-4 Temperature Data Logger: USB data transfer
Available Options
When temperature control is non-negotiable—think vaccines, food, or sensitive lab samples—the Yieryi RC-4 Data Logger steps in as a silent, digital watchdog. It's built for the gritty realities of warehouses, trucks, and cramped storage spaces, with an external sensor that sniffs out temps in spots you'd rather not crawl into.
Storage? It hoards up to 16,000 data points, so you can log for days without babysitting. A simple USB plug dumps all that intel to your computer, while its alarm screams if things heat up (or cool down) too much. No frills, no fuss—just cold, hard data to keep compliance officers happy and products safe.

As a chef who deals with sensitive ingredients, I needed something to monitor temperatures in my storage areas, and this device arrived on time and looked promising. I set it up in my walk-in cooler, and it started logging data right away. Over the past couple of weeks, it's been quite accurate, catching a few temperature spikes that could have ruined my stock. The ability to download all the data later is handy for keeping records, though I wish it had a more durable build. Overall, it does the job well and gives me peace of mind, even if it's not perfect. I'd recommend it for anyone in a similar line of work who needs dependable monitoring without extra fuss. 😊
- Pros: I quite liked how it keeps track of temperature without any hassle, storing a huge amount of data so I don't have to check it constantly. The alarm is loud and clear when things go wrong, which is a lifesaver for my work. It seems very reliable and easy to connect to my computer with a simple cable.
- Cons: I was a bit disappointed that the external sensor feels a bit flimsy and might not hold up well in rough conditions over time. It seems there's no way to adjust settings without a computer, which can be inconvenient if you're on the go.
