Mobeye Outdoor Temperature Monitoring

frozen blossomAccurate temperature measuring devices and remote frost alarms are important frost protection tools. The Mobeye ThermoGuard Outdoor version is also called the Mobeye Frost Alert CM4200X. It alerts you to weather conditions that could lead to crop loss. As long as the measured temperature is above the set minimum limit, no action is needed. As soon as the temperature gets in the alarm status, you’ll be informed by a phone call and text message, which tells you the accurate temperature.

The CM4200X is a freeze alarm and temperature alarm dialer for several outdoor applications. It helps farmers to protect plants and crops from frost damage. In springtime fruit growers and orchardists need to prevent their orchards and vineyards from serious frost damage and losses. By switching on irrigation systems and wind machines a water layer protects the blossom against frost. The Mobeye Frost Alert sends frost warnings when the temperature gets too low.

The Mobeye ThermoGuard CM4200X provides continuous monitoring of temperatures and warns the farmer when the temperature becomes too low. This battery-powered alarm system calls and / or texts to self-defined telephone numbers, once the temperature falls below the critical limit. The IP66 waterproof enclosure makes the device suitable for outside use.

The Mobeye Frost Alarm System makes it easy and affordable for growers to protect their crops from frost while reducing water usage. Night frost protection without sleep deprivation!

Frost workers

Mobeye Frost alarm – two versions

Mobeye CM4200X is a battery-operated temperature alarm, with external temperature sensor integrated communication module in an Outdoor enclosure (IP66).

If you want to see the temperature trend in a graph in addition to receiving alarms, choose the extended version: the Mobeye CML4275. The CML4275 has multiple features that make sense all year round. In addition to the lower limit for night frost measurement, an upper limit for the temperature limit can be set. If the limit is exceeded, the grower will receive a notification. This is useful for determining when to turn the foil and whether sprinkling is needed for refrigeration.

The Mobeye night frost detectors continuously measure the outside temperature and alarm when the limit value is reached. The Mobeye CM4200X only gives an alarm, possibly with repeats. The CML4275 displays, in addition to alarms, the temperature trend via an online application. Once in alarm status, the graph is refreshed every few minutes. The detectors can run on batteries for a long time. The temperature sensor is factory calibrated.

So the CM4200X is a pure alarm dialer without protocol or recording function. This means that this detector only alarms if the set temperature values ​​deviate or if any sensors connected to the NO/NC inputs detect errors. Only one temperature sensor can be connected and the open collector output is missing. Otherwise, the behaviour of the CM4200X is identical to that of the CML4275.
