ALLNET ALL4429 / temperature/humidity/pressure Sensor in met

Highlights:

• new compact aluminum desktop- / wallmounting case
• I2C Bus for multiplexing use
• angle fixings for wall mounting

Measure, control and regulate automatically and independently

ALLNET for years been pursuing the concept of intelligent control of processes in building over network and Internet. Intelligent building not only offers comfort, but actively promotes the reduction of energy costs.

Centrally managed and via network / internet accessible the ALLNET Home Automation products allow intelligent building

automation regardless of time and location.

The ALL4429 Combination sensor has a measuring range of 0 to 1023 mbar, -40 to +80 °C and 0...100 % RH

Combination Sensor of air pressure/humidity/temperature in desktop-/ wallmounting case

• measuring range of 0 to 1023 mbar / -40 to +80 °C (resolution 0,01 °C) / 0...100 % RH (resolution 0,5%)
• Aluminum housing with bracket for wall mounting
• Multiple multiplexing = multiple modules on one line
• Interfaces: 2x RJ45
• not compactible with ALL3000/ALL5000

Technical Details:

Multiplexing - Note to the operation of several sensors on one sensor port

Basically, it is for the ARM and MIPS-based systems possible, unlike to the ALL3000/4000 to operate more than

one sensor on a physical port.

Standard hardware requirement is that the sensors are equipped with 2 RJ45 connectors so that the sensor signal can be continued to the next sensor. The total cable length of 100 m does not increase thereby.

So that the sensors can be uniquely identified by the devices, it is necessary that these sensors have different software-I2C chip addresses and IDs. Sensors with the same address and adjustable chip ID can be combined. For sensors without adjustable ID address only one type of sensor can be connected per port.
