It has been designed as a cost effective, low power, self contained data logger. It has 2 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 a GPRS temperature/humidity data logger larm or pre-defined condition happens via SMS or GPRS. Alarm levels can be set for temperature inputs; it support User-defined SMS alarm messages.
CWT-J20 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 memory logs more than 1000 records. Flexible data logging interval starts from 1 minute up to 24 hours.
