1-Wire Temperature, Humidity, and Dew Point Sensor

1-Wire Temperature, Humidity, and Dew Point Sensor, -40 to 140 °F

At a time when controlling environmental factors such as temperature, humidity, and dew point can mean the difference between flawless operation and costly failures, NTI’s probe-style temperature, humidity, and dew point sensor delivers reliability and versatility in one solution.

Imagine managing a data center where servers run 24/7 and sensitive electronics must be safeguarded from moisture and heat - this is where this sensor excels. It simultaneously measures air temperature from -40 to 60 °C, relative humidity from 0 to 90%, and calculates the dew point in real time.

Thanks to its digital output signal, the sensor resists external interference such as electromagnetic noise or cabling issues, ensuring stable and error-free readings. Its high accuracy - ±0.4 °C above 5 °C and ±3% RH between 20 and 80% humidity - ensures that deviations are detected early before they cause damage. Potential risks become opportunities for preventive maintenance that extends system uptime and reduces costs.

Seamless integration with the NTI monitoring system makes this sensor a central component of any modern monitoring strategy. Through its robust RJ11 connector, it connects easily to the E‑1W unit, which serves as the network’s intelligent hub, sending alerts by email, SMS, or app notifications.

In applications such as pharmaceutical storage, where stable humidity levels are critical, the sensor continuously delivers accurate data directly to your monitoring dashboard. Imagine a sudden humidity spike pushing the dew point to a critical level - you receive an early warning and can act before condensation forms. With a standard cable length of 2 m and a maximum extension of up to 183 m, the installation area can be widely distributed without sacrificing accuracy.

Each sensor counts as three separate monitoring channels, emphasizing its scalability: up to eight sensors with full dew point tracking or twelve without this parameter can be deployed on a single system, ensuring high-efficiency network expansion. The compact probe, measuring just 95 × 15 × 16 mm, fits neatly into confined spaces such as ducts or enclosures for discreet yet powerful operation.

Engineered for durability and compliance, this sensor is the ideal choice for regulated environments where CE and RoHS standards are mandatory. With an outstanding Mean Time Between Failures (MTBF), it is built for long-term reliability. Power is provided directly by the E‑1W device, simplifying installation and reducing operating expenses.

Example from laboratory use:

Researchers monitor conditions inside a climate chamber where temperature fluctuations could distort results. The sensor captures variations with an accuracy of ±0.8 °C in low-temperature conditions and calculates the dew point, helping to prevent mold formation. The result: precise experiments, higher data validity, and faster scientific breakthroughs.

Whether in industrial environments protecting machinery from corrosion or in archives preserving sensitive documents, this sensor adapts perfectly - providing actionable data that improves processes. Its environmental resilience minimizes false alarms and enhances confidence in your monitoring system, allowing you to focus on what truly matters: innovation and growth.
