Introduction
Before you start mounting the 1-Wire Solar Multisensor and putting the device into operation, please read these
mounting and operating instructions carefully until the end, especially the section on safety instructions.

Product description
The 1-Wire Solar Multisensor is a combination sensor for solar-radiation, brightness and perceived temperature
that combines the advantages of semiconductor and photovoltaic sensors in one device.
The brightness sensor measures brightness values in the range of 10 - approx. 7000 lux, the PV sensor covers the
range up to approx. 1200W/m² and the temperature sensor outputs the felt temperature in the sun.
Since the solar sensor is a power sensor, the output is in watts per square meter (W/m²). The solar and brightness
sensors with their supplementary properties cover the entire range of applications for recording solar-radiation and
day/night detection and are therefore ideally suited for central light-, shutter- and shade control.
The 1-Wire Solar Multisensor is designed for permanent outdoor operation. The entire sensor is designed for a
temperature range of -40 to +85°C.
To ensure maximum reliability, the 1-Wire Solar Multisensor has an integrated monitoring of the supply voltage.
The sturdy plastic housing is designed for IP54 operating conditions. The cable entry is made by screw strangling
nipples. For wall mounting, a special mounting bracket is available for purchase as an accessory at our shop.
2.1
Photovoltaic sensor (solar sensor)
The photovoltaic sensor is designed to measure the solar-radiation in W/m². This makes the solar Multisensor very
suitable for controlling shading- or awning systems. The solar sensor covers an enormously large dynamic range
up to approx. 1200 W/m², which corresponds to approx. 1,000 up to 70,000 lux.
The sensor can be used well for estimating the expected performance of PV systems and finding a location.
Existing PV systems can be monitored by comparison measurements. Due to its design, the output voltage of the
sensor does not run with a linear characteristic curve and is subject to a certain temperature influence.
The measured solar-radiation power of the solar cell is output in watts per square meter (W/m²) by formula,
(evaluation script) and a variable for controlling a shading system is output.
The solar sensor is typically mounted on a mounting bracket (Art. No. 20003) at an inclination of approx. 45° with
orientation to the south. This allows a comparative measurement for PV systems. Rain and snow will also slide
faster from the top of the sensor.
