Your favorite Humidity and Temperature Smart Sensor just got even better! The HTP.xw uses the same outstanding mobile applications as the HT1 but now features:

Barometric pressure: Great for monitoring weather conditions, air density, altitude changes, vacuum storage and more

Even better accuracy: Uses the world's most accurate digital humidity/temperature sensor, with a typical accuracy of ±1.5%RH, ±0.1°C / 0.18°F

Water resistance: Sensor membrane and o-ring seals provide a durable, splash and rain proof design

Easy battery changes: Easy-change battery cap, making the infrequent battery changes a breeze

Even longer battery life: Battery life now estimated at over 2 years in normal conditions

Made in USA: Perhaps best of all, they're designed, supported, and now manufactured right here in America

And of course, like all SensorPush sensors, the HTP.xw can measure, record, and alert on dewpoint and VPD (vapor pressure deficit), and works seamlessly with the G1 WiFi Gateway for remote access.

You're busy. You know that proper temperature and humidity are important. But who has time for constant monitoring of conditions in the places they matter most, like refrigerators, guitar cases, humidors, attics, basements and crawlspaces?

SensorPush is the answer. Our Smart Sensors are compact and easy to use. They work with painstakingly designed mobile apps that not only make you love using them, but also require as little use as possible. It takes just a few moments to install our free app and pair your first sensor. After that, it's up to you.

If you love data, SensorPush has it, beautifully graphed in-app or easily exported to CSV for use in software like MS Excel. Either way, you'll be amazed by what you can learn from a complete history of minute-by-minute updates.

Or, sit back and relax. SensorPush is constantly monitoring conditions, even while you're sleeping or away. Upon your return, you'll be promptly alerted of any issues once data is downloaded via Bluetooth. If you’re going to be away for awhile, the sensor always maintains the most recent 30 days of data on board. For maximum peace of mind, add the SensorPush G1 WiFi Gateway for constant access and alerts from anywhere, via the Internet.

Temperature Range: -40°C - 60°C (-40°F - 140°F)

Humidity Range: 0 - 100%

(prolonged exposure to > 80% RH may create an offset of up to +3% in the readings. This effect gradually reverses after return to < 80% RH conditions)

Barometric Pressure Range: 300 - 1250mb / 8.86 - 36.91inHg

Temperature Accuracy

(20°C - 60°C / 68°F - 140°F): ±0.1°C / ±0.18°F typical, 0.3°C / ±0.54°F maximum

Temperature Accuracy

(Full Range): ±0.2°C / ±0.36°F typical, 0.3°C / ±0.54°F max

Humidity Accuracy

(@ 25°C / 77°F, from 0% - 80% RH ): ±1.5% typical, ±2% maximum

Humidity Accuracy

(@ 25°C / 77°F, from 0% - 100% RH ): ±2% typical, ±3% maximum

Barometric Pressure Accuracy: ±0.5mb / 0.015inHg typical, ±1.5mb / 0.044inHg maximum

Wireless Range: 100 meters line of sight under ideal conditions with no obstructions. Because of the way radio signals work, obstructions or interference can reduce the effective range substantially. Every situation is different, but by way of example, one of our test cases is a wood-framed 2,600 square foot, 2-story home. Sensors can be read virtually anywhere in, or immediately outside, the home.

Wet Conditions: The HTP.xw features O-ring seals and a special sensor membrane, making it water resistant. While it is not submersible, it is perfect for wet conditions outdoors, in greenhouses, etc.

Your possessions including guitars, pianos and other musical instruments, cigar humidors, wine cellars, incubators, greenhouses, art, family heirlooms, refrigerators and freezers benefit from careful and precise monitoring.

Stability of temperature and humidity over time is often the most important factor to avoid costly and irreparable damage. SensorPush makes it easy to see changes to help determine and take the proper course of action when necessary or rest easy when all is well.

Cousins & Sears is an award-winning creative technology design and development studio. The Brooklyn, NY-based team has worked on behalf of an incredibly wide variety of organizations from startups to the Fortune 500 across virtually every industry imaginable.

The two partners, Jonathan Cousins and James Nick Sears, are as hands-on as it gets. They bring a range of expertise and knowledge not only from graphic design to software development and electrical engineering, but also in diverse subjects such as history and music.

This broad base of experience means that everything from the sensor firmware to the apps themselves has been hand-crafted line by line. We believe the extra effort shows in the end result.
