The ALLNET MSR ALL4429 sensor, also known as the Luftdruck/Feuchte/Temperatur im Gehäuse sensor (Air Pressure/Humidity/Temperature Sensor in Metal Case), is a comprehensive environmental monitoring device designed for indoor applications.

This advanced sensor measures three critical environmental parameters:

• Air Pressure: Range from 0 to 1023 mbar with an accuracy of 0.01 mbar.
• Temperature: From -40°C to +80°C, with a resolution of 0.01°C.
• Humidity: Range from 0% to 100% RH with an accuracy of 0.5%.

It is housed in a compact aluminum case, suitable for desktop and wall installation. Here are some key features:

• Two RJ45 interfaces that allow multiplexing, facilitating multiple sensor connections.
• Designed for a wide range of operating conditions, including:
• Operating Temperature: -40°C to +80°C
• Storage Temperature: -45°C to +90°C
• Operating Humidity: 0% to 100%
• Storage Humidity: 0% to 100%

With CE certification and RoHS compliance, the ALL4429 meets high standards for safety and environmental responsibility. Its robust design and wireless connectivity make it an essential tool for modern building automation systems.
