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

With the multi-sensor a simple monitoring and recording of the indoor climate is possible.

For heating systems (individual room control) and ventilation systems it is an important sensor to achieve a good and stable control of temperature/humidity.
The living room sensor is also ideal for warning of possible mould formation.
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 Multisensor 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.
A brightness sensor is used to measure the twilight and brightness values within living spaces. The sensor can be used, for example, for the brightness-guided control of roller shutters or venetian blinds.


Assembly:

  • With this Multisensor it is now easy to measure temperature, humidity and brightness via a 1-Wire bus system indoors.

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).
