Product Description

The SensorPush HT1 Humidity and Temperature Smart Sensor with Alerts

You're busy. You know that proper temperature and humidity are important to your health and belongings. 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 20 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.

Technical Specifications

SensorPush HT1 Temperature and Humidity Smart Sensor Front
SensorPush HT1 Temperature and Humidity Smart Sensor Back

Dimensions: 40mm x 40mm x 16.5mm / 1.57" x 1.57" x 0.65"

Weight: 40g / 1.4oz

Battery: CR2477 (user replaceable)

Battery Life: Typ. over 1 year (more in normal conditions, less in extreme cold)

Sampling Interval: Every minute

On-board Data Storage: 20 days

In-App Data Storage: Unlimited

Compatibility: iOS 8+, Android 5.0+. Requires Bluetooth 4.0+ (also known as Bluetooth LE).

Remote Access: Compatible with the SensorPush G1 WiFi Gateway for remote access via the Internet.

Multiple Devices: One mobile device can monitor an unlimited number of sensors; one sensor can be monitored by an unlimited number of mobile devices.

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): ±0.3°C / ±0.5°F typical 0.5°C / ±0.9°F maximum

Temperature Accuracy

(Full Range): ±0.7°C / ±1.3°F typical 1.2°C / ±2.2°F max

Humidity Accuracy

(@ 25°C / 77°F, from 20% - 80% RH ): ±3% typical ±4.5% maximum

Humidity Accuracy

(@ 25°C / 77°F, from 0% - 100% RH ): ±4.5% 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: Like most humidity measuring devices, the SensorPush HT1 Smart Sensor is not waterproof. However, with care to prevent direct contact with water on the side with the vent hole (ideally facing the hole downward as well), it can be used outdoors in protected placements.

Why Monitoring is Important / Where to Use SensorPush

Your family's health depends on proper temperature and humidity. A study cited by the World Health Organization suggests that dampness is the root problem for one in five asthma sufferers in the U.S. It also estimates that half the homes in the U.S. are too humid. This encourages allergens like mites and fungi. It can even increase toxic airborne chemicals like formaldehyde.

Dry air is also a problem. Viruses thrive and spread more easily. Skin, eyes and mucous membranes dry out, causing discomfort and greater risk of infection. Yet humans cannot directly sense the level of humidity in the air. Without proper monitoring, it's easy to misuse humidifiers, trading one problem for another.

Your possessions including guitars, pianos and other musical instruments, cigar humidors, wine cellars, incubators, greenhouses, art, family heirlooms, refrigerators and freezers also 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.
 

SensorPush was created by Cousins & Sears Creative Technologists

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.
