This system is used for multi-point data accumulation e.g. if there are multiple points where temperature & Humidity (or any two analog parameters) are to be monitored and recorded locally. The alarms will be generated locally. Such multiple instruments will be interfaced to a PC through a centralized receiver.
Application Areas
Blood Banks, Pharmaceutical store rooms, Deep Freezer Temperature Monitoring, HVAC room temperature monitoring, Plastic molding plants, applications where production / production parameters are need to be monitored centrally.
Optional Features
USB port for each data logger to download the stored data locally
GSM ( SMS Facility ) in the receiver to report the alarming conditions to the concerned persons over SMS
