Reliable remote alerts

I was away on vacation and got an instant SMS when the humidity dropped too low in my plant room. Saved my rare orchids! The sensor is robust and weather-resistant.

Great range, battery life as advertised

Using this in a large commercial greenhouse. The 4G signal is strong even in the back corners. Only giving 4 stars because the app interface could be slightly more intuitive, but functionality is solid.

Perfect for my server room monitoring

Setup was incredibly easy. I plugged in the SIM card, and within minutes I was receiving temperature data on my phone. The alert system gives me peace of mind when the AC acts up.

Good value for money

Compared to other industrial sensors, this is very affordable without sacrificing quality. The E-Ink display is easy to read in bright sunlight. Shipping via SF Express was super fast.

Exactly what I needed

No WiFi needed which is a huge plus for our storage units. The historical data graphs help us identify trends over time. Customer support was also very helpful during setup.

Essential for cold chain logistics

We use these for our pharmaceutical shipments. The data logging is accurate and the export feature makes compliance reporting very simple. Highly recommended for professional use.
