iMETOS ECO D3 is designed to monitor soil moisture at the crop and to present this data on FieldClimate.Com. The GPRS, EDGE or
CDMA networks are allowing you to install the device wherever you need it. iMETOS might be used to monitor only one site or it
can be used to monitor several sites in a short distance. These sites will be connected by cables.
iMETOS ECO D3 supports different ways of soil moisture measurement. All this different sensors will need a different
electronic. For this purpose it always consists of the main PCB (responsible for the logging and the communication) and in
minimum one second PCB (responsible for sensor evaluation). If it is made to monitor one spot this second and only sensor
evaluation PCB will be in the same box than the main PCB. If it is made to monitor several sites with a cable connection this
other sites will have their own sensor evaluation PCBs in own boxes.
All the PCBs for sensor evaluation do have a line going towards the iMETOS and a line going towards the next PCB for sensor
evaluation. Several of this sensor evaluation PCBs can be linked together in a chain. Nevertheless it might be needed to create
a network where the sensing sites are going in two or 3 directions away from the iMETOS. In this case the iMETOS ECO D3 supports
up to 3 sensor chains. For sensor chain 2 and 3 an extension PCB is needed.
