GSM/GPRS/GPS temperature controller, high speed temperature sensor, build-in humidity sensor, powerlost alarm

      CWT5016 has been designed as a cost effective, low power, self contained data logger. It combines 4 digital inputs, 4 drivable relay outputs, 4 analog inputs and 4 special temperature sensor inputs with embedded GSM/GPRS module to provide an all in one instrument for data logging, remote data acquisition, alarm and control.

It uploads real time data on schedule or alarm or pre-defined condition happens via SMS or GPRS. Alarm levels can also be set for any of the digital inputs, analog inputs and temperature inputs; it support User-defined SMS alarm messages and the outputs can also be controlled via SMS or GPRS.

      CWT5016 comes with an easy to use configuration SW for setting up all parameters, including setting alarm levels or states and pre-defined conditions for GPRS transmit etc. The configuration can be done on a PC or from sms command.

Its internal 256KB memory logs more than 1000 records. Flexible data logging interval starts from 1 minute up to 24 hours.
