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)

Temperature Accuracy

(0°C - 60°C / 32°F - 140°F): ±0.2°C / ±0.36°F typical, 0.4°C / ±0.72°F maximum

Temperature Accuracy

(Full Range): ±0.6°C / ±1.08°F typical, 1°C / ±1.8°F max

Humidity Accuracy

(@ 25°C / 77°F, from 10% - 90% RH ): ±2% typical, ±4.5% maximum

Humidity Accuracy

(@ 25°C / 77°F, from 0% - 100% RH ): ±4% typical, ±7.5% 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 HT.w 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.
