Application Case

Quickly responding, G771 uploads the alarm data via Internet
as soon as possible, thus ensuring the safety of lives and property.

Case of Agricultural IOT Environmental Monitoring

G771 can quickly upload the data collected by sensors in agricultural
greenhouses to remote servers through the LTE or GPRS network to facilitate
the control center to monitor the greenhouse dynamics
in real time and respond in time.

Transmission of Charging Pile Data Through Internet

As a charging pile works, its running data can be quickly uploaded to
a cloud server through the connected G771 to help the back-end operating
personnel uniformly manage the data.

Remote intelligent meter reading

Remote intelligent meter readingMay 05,2022

In nowadays, the large number of various meters are dispersed in different locations, some of which are remote and difficult to access, a remote meter reading system is urgently needed to relieve staff of utilities from heavy but inefficient tasks.Traditionally, the utilities companies used to hire thousands of meter readers to go around to read the meter, and always spend much money on traffic and labor.
