Senzor vlhkosti ALLNET 98828 voľne stojaci bezdrôtový

The ALLNET ALL4429 Combination Sensor is a compact aluminum desktop or wall-mountable unit that measures air pressure, temperature and relative humidity. Designed for networked building automation, the sensor supports I2C bus multiplexing and provides two RJ45 interfaces for integration into ALLNET systems. The housing includes angle fixings for secure wall mounting and an aluminum bracket for flexible installation. The sensor measures 0 to 1023 mbar, -40 to +80 °C and 0 to 100 % RH with fine resolution suitable for monitoring indoor environmental conditions.

Advantages

The device combines three measurements — air pressure, temperature and humidity — in a single compact aluminum enclosure suitable for desktop placement or wall mounting. It supports I2C multiplexing to allow multiple modules on one line and provides two RJ45 interfaces for network integration. The robust temperature and humidity resolution enables precise monitoring for building automation and climate control systems.

Suitable for

• Indoor climate monitoring in homes and offices
• Integration into ALLNET building automation systems
• Energy management and HVAC system monitoring
• Environmental data collection for control and logging

How to use

Install the sensor on a desk or fix it to a wall using the included angle bracket and fixings. Connect the device to the local automation network via the RJ45 connectors and configure multiplexing over the I2C bus if several modules are used on a single line. Incorporate the sensor into the ALLNET control platform to enable central access, data logging and automated control based on measured values.

Recommendations

Place the sensor away from direct heat sources, drafts and direct sunlight to ensure accurate temperature and humidity readings. For multi-module installations, verify I2C bus addressing and multiplexing settings to avoid conflicts. Follow ALLNET system guidance for network integration and data collection.
