This is a system which has a temperature data logger combined with a phone call & SMS alert system. The main features are:
the system continuously checks the temperature of the environment where it is installed. The frequency of collecting data can be programmed in the system which is called sampling interval. If temperature is recorded every 5 seconds, then the sampling interval is 5 seconds. For a critical storage system such as a medicine cold room (temperature between 2 to 8°C), the sampling interval can be kept as 1 minute. For a less critical system such as a warehouse (temperature between 2 to 8°C), the sampling interval can be kept as 10 minutes. The alert system can be programmed for lower and higher level of temperature eg. for a medicine cold room (temperature between 2 to 8°C) a lower alarm level can be kept as 2.5°for 2 minutes and higher alarm level can be kept as 7.5° for 2 minutes. This means that if the temperature goes below 2.5°for 2 minutes or goes above 7.5°C for 2 minutes, an alarm condition will be generated. In this case different alerts such as a local strobe/beacon light, phone call & SMS to operators, Email to operators etc. will be generated as programmed.
This brief video explains the functioning of the whole system
The system is generally supplied as a complete assembled system. The customer needs to connect only the battery, AC power supply & sensor. Then upon inserting the SIM card the system starts working. Please see the following video:
The recorded data can be viewed on the free T&D Graph software. The details for viewing the data can be seen in this video
This video demonstrates installation of the necessary software for programming and recording of temperature and humidity
This video shows initial programming and subsequent modifications of the monitoring system for recording, alerts, data transmission etc.
