Temperature monitoring products

Temperature is the most popular parameter to remotely sense, datalog and control and is the parameter most likely to be needed to monitor and log to enable proof of how products have been stored or processes carried out.

The devices shown on the right hand side will sense the temperature using one or more external sensors. In addition, some devices can use humidity and other sensors for remotely monitoring other parameters.

The products fall into the following main categories: Standalone or Networked (GSM, Ethernet LAN or WiFi) Single Sensor or multi-sensor.  Networked (LAN) systems will normally require an external power supply except in the case of the Power over Ethernet (PoE) devices which use a PoE switch to provide power over the ethernet connection.

Applications include:

  • Temperature in Server Rooms
