Temperature Wireless Sensor Wireless Water Tank Level Alarm Monitoring



G7          Industrial Wireless Sensor System

With G7 temperature humidity wireless sensor and Base Station, you can start monitoring your premises environmental condition online.

Wireless sensor G7 transmits measurement to Base Station via wireless signal. Base Station collects all the wireless sensors readings and uploads to central server in interval via Modbus TCP protocol.

G7-Centre App receives data from Base Station over Internet or LAN.

“Wireless Client” displays the incoming data in graphs, and saves into local storage for analysis. By monitoring and understanding how environmental changes, you can adjust your air conditioner or heater to save energy and money.


[In the Package]

1 x Base Station& RF Antenna   

1 x AC/DC Adaptor       

1 x Ethernet Cable   

Up to 64 x Wireless Sensors in one single system   



up to 64 wireless sensors   

max. 1200m wireless distance  

support both temperature and humidity sensors 

user configurable upload interval  

allow user to add sensors with setup software 

  • free wireless client app for windows, iPad, android
  • no server is needed in direct mode
  • larger capacity internal battery
  • new low power CPU for average 18 months operation


[How it Works]

(1)     Wireless Sensor

The sensor transmits the temperature or humidity reading to Base Station wireless over radio frequency up to 1200 meter unblocked. Its internal battery operates for average one year.

* G7-TM                 Wireless Temperature Sensor

* G7-TX                  Wireless Temperature Sensor, external 80mm steel housing probe

* G7-T2                  Wireless Temperature Sensor, 2m cableexternal probe

* G7-TH                  Wireless Temperature &Humidity Combo Sensor

(2)     Base Station

Base Station receives reading from max. 64wireless sensors in a range of 1200m. This station is connected to the Internet or LAN connection. Information of all sensors collected in one data record is then sent to the central computer over LAN or Internet in Modbus TCP protocol.


[Free Software]

(1)     G7-Centre App

By using G7-Centre app, users receive data from Base Station over LAN or Internet. Data will be displayed in listing and saved into file for future analysis.

(2)     Wireless ClientApp for Windows, iPad, Android

Wireless Client receives data from Base Station. The app displays the live data in graphics, and alert user when measurement is beyond alarm range. At the same time, it saves data in local storage for historical display in graphics for comparison and report generation.
