MarCELL Cellular Temperature, Humidity & Power Monitor (Verizon) - Made in the USA - For RVs, Pets, Second Homes, and Greenhouses - 24/7 Monitoring & Alerts

Plug in and Connect: How MarCELL Monitoring Works Once registered, MarCELL can be plugged into any standard wall outlet and immediately connects to selected 4G cellular networks for 24/7 monitoring of ambient conditions in your Home, RV, or other property. No Wi-Fi is required, as MarCELL utilizes the nation's largest 4G LTE cellular networks.

Set Your Preferences Through the Sensored Life App, you can set your preferences and alert notifications for up to 9 contacts. MarCELL will monitor and report indoor temperature, humidity, and power status. All contacts will receive alerts via text, call, or email if temperature or humidity exceed set levels, or power is lost.

Monitor What Matters MarCELL updates conditions in the App every 8 hours, unless power is lost or the temperature or humidity exceeds preferred levels. Should conditions extend beyond set preferences, instant alerts are sent to all contacts. Additional charges apply for on-demand, current conditions (outside of the 8-hour updates).

Monitor Your RV and Pets Safeguard your RV and pets from extreme heat and humidity, as well as unexpected power loss when you are away. If these levels drop below or exceed your set preferences, MarCELL will send you an alert via text, email, or call to notify you about any potentially unsafe conditions.

Keep an Eye on Your Home Protect your home while you're away. Avoid unwanted damage to your valuable investment and assets. MarCELL tracks ambient temperature, humidity, and power status to send you instant alerts in the event that these conditions become unsafe or need immediate attention.

Server Room Stability Keep servers and IT equipment protected from overheating, excess humidity, power loss, and water leaks. Ensure you know exactly what's happening when you are away from the building, with instant alerts sent to your phone.

Greenhouses, Wine Cellars, and More Monitor the temperature and humidity of your greenhouse or wine cellar to ensure conditions never deteriorate without your knowledge. MarCELL helps you keep an eye on any urgent temperature, humidity, and power needs in most environments.
