The miniature wireless sensors can be placed virtually anywhere and in its simplest form, you only have to place the sensor wherever you want to measure to get your required data.
The practical placement of the sensor does, however, impact both the radio communication range and measurement accuracy. Below you can find practical advice for sensor placements in different applications.
Metal can severely impact radio range
Placement inside containers
A common application for wireless temperature sensors is to monitor fridges, freezers, coolers, warehouses, etc. There are some pitfalls in doing temperature measurements in these applications.
Most cold storage equipment is built from metal. For a wireless signal, metal will absorb and/or block a lot of the energy in the radio signal, which can lead to a significantly reduced communication range. It is therefore advised that the Cloud Connector is relatively close to the cold storage cabinet for this application.
A special sensor accessory has also been developed to greatly simplify installation in cold storage applications, see Ambient Range Extender. This accessory serves a dual purpose, assure the temperature measurement is accurate in measuring the air temperature in the cold storage application while at the same time giving maximum radio range for the sensor system.
Placement on metal surfaces
Sensors placed flat on metal will have significant radio range reduction. Avoid placing sensors on metal, unless the purpose of the installation is to measure the surface temperature of the metal.
Temperature monitoring of industrial equipment
For applications where the temperature of a metal surface is the target, the sensor can be placed flat on metal. This will give a very good representation of the object temperature. As the range will be reduced by placing the sensor flat on metal, the Cloud Connector needs to be relatively close to the measurement point. If this is not possible, a special sensor accessory has been developed to give a great radio range while maintaining an accurate representation of the object temperature.
