1-Wire outdoor Multisensor surface-mounted for temperature, humidity and brightness Standard

The 1-Wire Multisensor Outdoor is designed for permanent installation in rain and weather protected outdoor areas. The sensor can also be used in rooms with permanently high humidity, e.g. conservatories, saunas or cellars. The sensors must be protected from rain or other direct exposure to water.

A calibration of the sensors is not necessary. They can be put into operation immediately without waiting time. In addition to the 1-Wire component (DS2438) for detecting humidity, brightness and operating voltage, the 1-Wire outdoor sensor also includes a high-precision temperature sensor (DS18B20) with a resolution of 12-bit accuracy. The integrated humidity sensor has a high accuracy in the range of 10 - 85% relative humidity.

The brightness sensor is used for the metrological recording of twilight and brightness values for outdoor areas or areas with permanently high humidity values. The sensor can be used, for example, for the brightness-guided control of roller shutters or blinds (day / night detection).
A special photodiode with a human-like detection light spectrum is used

Assembly

  • With this Multisensor it is now easy to record temperature, humidity and brightness via a 1-Wire bus system in rain-protected outdoor areas. You can mount the multisensor e.g. under the roof overhang on your house. The sensor must not be exposed to direct rain.
  • Ideally suited for areas with high humidity

Function and application

  • Temperature sensor DS18B20: -40°C to +60°C, limited by housing (sensor element: -10°C to +125°C) additional DS18B20 temperature sensor
  • Air humidity sensor DS2438: Capacitive sensor, DS2438, 0% to 100% relative humidity. As air humidity sensor a sensor of the manufacturer Honeywell is used.
  • DS2438 light sensor: measuring behaviour simulates the human eye (not UV light).
