MarCELL is a remote monitoring device that measures indoor temperature, relative humidity and power status in your home, RV, greenhouse, etc. The setup is simple, with an intuitive interface that allows you to set your own temperature and humidity ranges. If temperature or humidity exceed the ranges you select or power is lost, you will be immediately contacted by your preferred method of phone, text or e-mail.
MarCELL detects water leaks with the addition of a SPuck water sensor. In an open field with a clear line-of-sight, there is solid communication between a SPuck and a MarCELL of well over 320 feet. Purchase the SPuck here.

The Marcell cellular temperature monitor operates wherever there is a cellular signal from the Verizon or AT&T 4G LTE networks. The specific coverage depends on the version you purchase.
The Marcell monitor does not rely on a Wi-Fi or internet connection at the location being monitored, as it uses its own pre-activated cellular connection to send data and alerts.
