Eastron Modbus mapsEastron Modbus mapsEastron measuring units are typically 1- or 3-phase measuring units that can be purchased at extremely favorable prices (e.g. on Amazon, Aliexpress). They are usually not MID compliant. Typically, they can be used for building automation and smaller equipment. A surprisingly large number of measurements are performed, the status of which can either be viewed on the display or queried via remote access using the Modbus RTU protocol. Not all Modbus parameters are available with all Eastron devices.

UICPAL Temp.humi.sensorUICPAL Temp.humi.sensorThe relative humidity of air is the ratio of the absolute humidity in the air to the absolute humidity at saturation at the same temperature, which is a percentage. (that is, the percentage of the amount of water vapor in the air in a certain time and the amount of saturated water vapor at the temperature) is expressed by RH.
