Temperature Humidity Sensor ALLNET ALL4409

The ALLNET ALL4409 Temperature Humidity Sensor is a wired outdoor sensor intended for freestanding installation to monitor ambient temperature and relative humidity. Designed for outdoor and semi-outdoor environments, the sensor delivers continuous environmental readings and is built for stable operation in variable weather conditions. The unit is compact and lightweight at approximately 1 kg, making it straightforward to position where monitoring is required.

Advantages

The sensor offers precise temperature and humidity measurement with a wired connection that ensures consistent data transmission without reliance on wireless networks. Its durable enclosure is engineered for outdoor exposure and protects internal components from common environmental factors. The straightforward freestanding form factor simplifies installation and relocation, while the sensor’s design focuses on reliable long-term operation and minimal maintenance.

Suitable for

• Outdoor environmental monitoring for gardens, yards, and open storage areas
• Weather stations and local climate observation points
• Agricultural sites such as greenhouses and small farms where wired sensors are preferred
• Building exteriors and technical installations that require ambient condition logging

Key specifications

• Measurement types: air temperature and relative humidity
• Connection: wired interface for stable data transfer
• Mounting: freestanding placement; suitable for outdoor use
• Weight: approximately 1 kg for easy handling and positioning
• Construction: weather-resistant enclosure designed for outdoor exposure

How to use

Place the sensor in a representative outdoor location away from direct heat sources and sheltered from heavy driving rain if possible to improve longevity and measurement consistency. Connect the wired interface to the monitoring system or data logger following the monitoring equipment’s connection instructions. After initial placement and connection, allow the sensor time to stabilize before relying on logged values; periodic visual inspection is recommended to ensure the housing and cable remain intact.

Recommendations

For accurate and reliable results, install the sensor in a location with good air circulation and avoid locations that may be subject to direct sunlight reflecting off nearby surfaces. Schedule occasional checks for dirt, debris, or physical damage and follow the connected monitoring system’s calibration procedures if long-term accuracy verification is required.
