GMM Wireless Temperature & Humidity
Monitoring System

GMM System | °C/%RH Sensor | Mini Computer

Product Description

  • Mini Computer Portal with access software
  • S1 bluetooth temperature and humidity sensors
  • G1 gateway with LAN & USB power supply connection

The gateway connects to power and to your office network, and from there to the Internet. The gateway receives wireless communication from the bluetooth wireless sensors within 100 meters/328 feet without any problems - even longer outdoors. You normally just need one gateway, but if your sensors are spread out over a huge area (outside of 100 meters) or if you have several physical locations, then you will need more.

Wireless battery powered temperature and humidity sensors for fixing to a wall or appliance or temporarily placed on a surface or shelf. Automated data collection and upload to the computer portal with functions enabling an on the spot reading to be recorded in the min computer.

Simple installation coupled with an easy to use Software Portal make the GMM Environment Monitoring System a desirable solution for organisations wanting in-house access to their environmental data with minimal interaction with I.T and computers.

  1. Connect the G1 gateway to a LAN socket or router and a mains power socket via the supplied cable and power supply.
  2. Connect the S1 temperature and humidity sensors to the gateway
  3. Access the software portal and rename your sensor and gateway
  4. View live data
  5. Manage alarms
  6. Analyse historic data
  7. Generate PDF reports

This system enables you to measure temperature and humidity at many locations and view all your data on any mobile device or computer with internet access.
