Industrial 8 Industrial 10 cold storage / freezer temperature alarm SMS alarm hosts and by the temperature and humidity testing terminal with LCD display composition, can detect power lines, call SMS alarm, over-temperature alarm messages.

working principle:

The temperature sensor is placed in the refrigerator (refrigerator), the real-time monitoring of the refrigerator temperature (cold) and placing the collected temperature values are displayed on the LCD monitor, LCD liquid crystal display can be hung on the outside of the refrigerator or cold can conveniently watch place. Refrigerators (cold) temperature alarm determines whether the current temperature is exceeded the user set temperature range, once the temperature exceeded, immediately send alarm messages to the designated person the phone.

Refrigerators (cold) temperature SMS alarm system developed according to the characteristics of the cold storage management, enabling unattended remote monitoring, high and low temperature limit alarm, power failure alarm, live sound and light alarm, SMS check real-time temperature. Alarm host with 8 digital signal inputs, which can be accessed various sensors 8 digital signals; at the same time with 4 outputs can directly drive a relay.

System functions:

♦ Real-time monitoring of refrigerators (cold) temperature value, when it is detected in the refrigerator (cold) temperature exceeds the set temperature range, an alarm message is sent immediately to the designated person the phone, which can issue six phone numbers.

♦ fridge (refrigerator) power supply line to detect an incoming call: When the refrigerator (refrigerator) Power line failure or line failure, the control panel detects a power failure signal immediately send alarm messages to the designated officer, the line returned to normal and will also send alarm information to the specified lift staff phone. .

♦ site LCD display, real-time display of the current temperature and humidity, large screen large font, easy management personnel on-site viewing.

♦ When the temperature exceeds a threshold live sound and light alarm, sound and light alarm can access the duty room to facilitate duty-site processing (optional).

♦ SMS notification doors opened illegally, Optional Magnetic (optional).

♦ over-temperature or power failure alarm, optional dial-up alarm; dial-up managers to take turns to call the phone number, hang up automatically after three beeps, then sends alarm messages (optional).

♦ Temperature alarm system temperature can be in the form of text messages regularly sent to the designated mobile phone that supports SMS query duty current temperature and humidity.

♦ temperature alarm system with a set of SMS commands, the user can direct remote arm and disarm SMS instruction, set alarm thresholds, alarm contents and alarm number.

♦ a refrigerator (cold) temperature alarm system alarm host can be connected to a plurality of temperature and humidity detectors, each temperature sensor has a separate number, when any one of a temperature probe detects temperature exceeds the set range, all will send SMS alarm.

Alarm message format: The machine name + temperature terminal number + current temperature and humidity values + SMS alarm content.

Such as: hearing room high current 28.5 ℃, 80%, exceeding the upper limit of temperature and humidity!

♦ control panel also has a plurality of input ports and output detection alarm control port, you can connect other probe detection alarm and SMS remote control.
