Software / Evaluation
The wind sensor delivers 4 pulses per revolution. To calculate the wind speed, the pulses are usually counted for
a period of e.g. 1 minute, in our example by the ESERA 1-Wire S0 counter 11211 and then divided by the factor 4
(4 pulses = 1m/s). The result is the wind speed in m/s.
To get to Km/h, the value m/s is multiplied by 3600 and then divided by 1000.
Formula:
Counter reading new - Counter reading old = Delta
Wind speed: m/s = delta / factor (4), Km/h = m/s x 3600 / 1000

Operating conditions
The sensor may only be operated at the specified voltages and ambient conditions. The operating position of the
device is vertical. The sensor is designed for continuous outdoor operation.
Due to the heating inside the sensor, the housing heats up. Do not operate the sensor in an
environment in which flammable gases, vapors or dusts are present or may be present.

Components, modules or devices may only be put into service if they are mounted in a contact proof housing.
During installation they must not have power applied.
Tools may only be used on devices, components or assemblies when it is certain that the devices are
disconnected from the power supply and electrical charges stored in the components inside the device have been
discharged.
Live cables or wires to which the device or an assembly is connected, must always be tested for insulation faults
or breaks.
If an error is detected in the supply line, the device must be immediately taken out of operation until the faulty
