T/RH with Radiation Shield

Topic refers to T/RH IP67 Sensor with Outdoor Radiation Shield(TDSPT8x2.ORS) and T/RH Probe Heavy Duty with Outdoor Radiation Shield (TDSPT8x9.ORS)

Modern environmental monitoring requires more than simple temperature readings. In agriculture, greenhouses, warehouses, industrial facilities, and outdoor installations, precise temperature and relative humidity measurements are critical for maintaining product quality, operational efficiency, and environmental stability.

Aranet T/RH Probe Heavy Duty with Outdoor Radiation Shield is a wireless sensor with an external probe, engineered for environments where durability and measurement accuracy are non-negotiable. The PTFE probe and silicone cable ensure reliable temperature and humidity monitoring in condensing and tough industrial settings. The Outdoor Radiation Shield prevents false readings and improves the accuracy of the measurements in the outdoor environment.

Like all Aranet Pro series sensors, this sensor is compatible with the Aranet base station and Aranet Cloud.

T/RH IP67 Sensor with Outdoor Radiation Shield

The T/RH IP67 sensor is designed for harsh outdoor environments where durability and weather resistance are essential. It continuously measures environmental temperature and humidity while maintaining stable performance under dust, rain, moisture, and changing outdoor conditions.

Measurements

  • Temperature (T) — the thermal condition of the environment.

  • Relative Humidity (RH) — the amount of moisture present in the air compared to the maximum moisture the air can hold at a specific temperature.

These measurements are essential because temperature and humidity directly affect

  • Crop growth and greenhouse performance

  • Food storage and cold chain quality

  • HVAC efficiency

  • Industrial processes

  • Mold prevention

  • Equipment reliability

  • Worker comfort and safety

Accurate humidity and temperature monitoring helps businesses reduce waste, improve energy efficiency, and maintain stable environmental conditions.

The device features

  • Temperature range: -40 °C to 60 °C

  • Humidity range: 0–100% RH

  • Accuracy: ±0.3 °C temperature / ±2% RH

  • Protection rating: IP67

  • Wireless communication via the Aranet PRO network

  • Up to 10 years of battery life, depending on measurement interval

Matter of IP67

Why the IP67 Rating Matters

The IP67 protection class is one of the sensor’s most important features.

Meaning of IP67

  • 6 = complete dust protection

  • 7 = protected against temporary water immersion

Why It Is Useful

This allows the sensor to operate reliably in:

  • Rain

  • Dusty industrial areas

  • Agricultural environments

  • Outdoor storage facilities

  • High-moisture environments

Without strong enclosure protection, moisture or dust contamination can damage sensing elements and reduce measurement accuracy over time.

Importance of the sensor

Importance of the Outdoor Radiation Shield

One of the most meaningful features is the outdoor radiation shield.

What It Does

The shield protects the sensor from:

  • Direct sunlight

  • Thermal radiation

  • Heat reflection from nearby surfaces

Why This Matters

Without a radiation shield:

  • The sensor body can heat up from the sunlight

  • The measured temperature becomes artificially higher

  • Humidity calculations become inaccurate

The radiation shield allows air to circulate naturally while blocking direct solar heating, resulting in more accurate environmental readings. This is especially important for:

  • Greenhouses

  • Weather stations

  • Outdoor agriculture

  • Climate research

  • Environmental compliance monitoring

T/RH probe Heavy Duty with Outdoor Radiation Shield

The T/RH Probe Heavy Duty version is built for more demanding professional applications where the sensing probe must be physically separated from the transmitter body.

Measurements

  • Temperature (T) — the thermal condition of the environment.

  • Relative Humidity (RH) — the amount of moisture present in the air compared to the maximum moisture the air can hold at a specific temperature.

Importance

The external probe offers several advantages:

Better Placement Flexibility

The probe can be installed:

  • Inside ventilation ducts

  • Near crops

  • Inside machinery

  • In hard-to-reach areas

  • In enclosed monitoring points

while keeping the main transmitter protected elsewhere.

Improved Measurement Accuracy

Separating the sensing element from electronics reduces:

  • Self-heating effects

  • Heat interference from equipment

  • Environmental bias

This improves measurement stability in industrial conditions.

Heavy-Duty Applications

The sensor is intended for:

  • Industrial HVAC systems

  • Food storage facilities

  • Manufacturing environments

  • Smart agriculture

  • Harsh outdoor deployments

Why is relative humidity monitoring necessary

Humidity is often underestimated, yet it strongly affects:

  • Plant diseases

  • Mold growth

  • Corrosion

  • Product spoilage

  • Human comfort

  • Electronics reliability

For example:

  • High humidity can damage stored goods

  • Low humidity may affect industrial processes

  • Greenhouses require precise humidity balancing for optimal crop growth

The ±2% RH accuracy of these sensors helps maintain stable environmental conditions with professional-grade precision.
