ALLNET MSR sensor ALL4420 / sensor for humidity and temperature in the housing *white*

Highlights: new flat desktop / wall housing made of aluminum I2C bus for multiplexing use Measuring range -40...+125 °C, 0...100%RH resolution temperature 0.01 °C, resolution humidity: 0.01% measuring accuracy Temp in the entire range approx. +/- 0.6° (Typical: -20 + 90° = +/- = 0.2°) Measuring accuracy Humidity in the entire range approx. +/- 3% (Typical: 0~80% +/- 1.5%) ONLY COMPATIBLE WITH ALL34xx/350x/4500/5000 Angle brackets for wall mounting Measure, control and regulate automatically and independently
ALLNET has been pursuing the concept of intelligent control of processes in building technology via network and internet for years . Intelligent building technology not only offers more comfort, but also actively promotes savings in energy costs.
Centrally controlled and accessible via network/internet, ALLNET building automation products enable intelligent building technology regardless of time and location.Technical Details: Humidity Sensor Specification Parameter Condition Value Units Sensor Humidity Accuracy tolerance1 Type. ±1.5 %RH Max. - Repeatability2 Low, typ. 0.21 %RH Medium, typ. 0.15 %RH High, typ. 0.08 %RH Resolution Typ. 0.01 %RH Hysteresis at 25°C ±0.8 %RH Specified range3 extended4 0 to 100 %RH Response time5 t63% 86 s Long-term drift Typ.7 %RH/yr Temperature Sensor Specification Parameter Condition Value Units ALL3020 Accuracy tolerance1 typ., 20°C to 60°C ±0.1 °C Max. - Repeatability2 Low, typ. 0.15 °C Medium, typ. 0.08 °C High, typ. 0.04 °C Resolution Typ. 0.01 °C Specified Range - -40 to 125 °C Response time 8 t63% >2 s Long Term Drift max °C/yr Multiplexing - Note on operating multiple sensors on one sensor port
This is basically the case with ARM and MIPS-based systems possible, in contrast to the ALL3000/4000, to operate more than one sensor on one physical port.
The hardware requirement is that the sensors have 2 RJ45 connections so that the sensor signal can be passed on to the next sensor. The total cable length of 100 m does not increase.
In order for the sensors to be clearly identified by the devices, it is necessary that they have different I2C chip addresses and IDs on the software side. Sensors with the same chip address and adjustable
ID can be combined. For sensors without an adjustable address, only 1 sensor type can be connected per port or via the ALL4404 8-fold multiplexing HUB.
