Gsm Based Loggers

In this system a portable sensor is located at the point of measurement and data will be transmitted over wireless and logged and monitored centrally at local level. The systems configuration will be as followsSmart sense Wireless Sensor: These sensors will be installed at points where the parameters (Temperature or Humidity) are to be monitored. Each will have inbuilt wireless module which will transmit the data over 2.4 GHz wireless network.Smart Receive Wireless Receiver: The centralized wireless receiver will receive the data from the sensors by sending query at regular intervals and transfer the data serially over RS232Smart Scan Universal Data Logger: Universal data logger will receive the data over serial input and store it with reference to time and date. The Smart Scan will be connected to local PC via RS 232 for monitoring.
