About this item

  • Accurate: Premium sensing component with accuracy of ±3%RH, ±0.3°C / 0.5°F. Professional-grade components, assembled into devices you can trust. For even more demanding applications, the device is easily calibratable to a trusted reference, or try the SensorPush HT.w or HTP.xw for even greater out-of-the-box accuracy. Whichever SensorPush you choose, you'll enjoy reliable, quality monitoring of environmental conditions including air temperature, relative humidity, dewpoint and VPD
  • Versatile: With its small, attractive design, the HT1 is at home just about anywhere: in a refrigerator, freezer, greenhouse, humidor, wine cellar, instrument case like guitar or violin, a piano, outside as a mini weather station, around the house monitoring a humidifier or thermostat in baby nursery, in the attic, basement, crawlspace, reptile tank, terrarium, plants in a grow tent, drying and curing, a chicken coop or egg incubator and more
  • Flexible: Use the sensor and your phone via Bluetooth or add a SensorPush G1 WiFi Gateway (sold separately) for data and alerts via Internet. With a G1 Gateway, get updates and push notifications when conditions exceed min/max alarm settings anywhere, ask Alexa for updates, or view data on a computer in our web dashboard. Great for a vacation home, garage, server room, data center, ensuring a dog or other pets are safe in an RV (cellular hotspot required) or anywhere remote monitoring is useful
  • Powerful: Line of sight Bluetooth range of 325 feet keeps you up to date, even on the other side of your home. Obstructions such as walls or doors will reduce this, often considerably, but every day in real world conditions, customers happily monitor difficult situations like walk-in coolers, safes, inside a wall or even on a roof. The small size, convenient mounting hole, and long battery life (typically over 2 years) simplify placing one or multiple sensors wherever they are needed most
  • Easy one-time setup with our beautifully designed, free app (iOS or Android). Quickly view a digital summary of current conditions for your entire system of connected SensorPush devices. Drill deeper with integrated data logging and graphing with 20 days of storage on the sensor and unlimited in-app storage for unlimited devices using our custom built high performance database. Export any data recording to CSV for analysis or archival with Excel, Google Sheets, etc, and calibrate with ease.

Product Description

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, with unlimited storage, 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.

SensorPush in Refrigerator

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.

Technical Specifications

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 (0-60°C) ±0.3°C / ±0.5°F typical 0.5°C / ±0.9°F maximum
Humidity Accuracy @25°C 20-80% ±3% typical ±4.5% maximum
Battery CR2477 (included, user replaceable)
Battery Life Typical 1-2 years (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 11+, Android 5.1+. 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
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. The SensorPush HT.w and HTP.xw are preferred for wet environments. 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.
Dimensions 40mm x 40mm x 16.5mm / 1.57" x 1.57" x 0.65"
Weight 40g / 1.4oz

Excellent temp device for HVAC, fridge, growhouse monitoring. Easy set up via data rich phone app
I bought two SensorPush monitors to put in my new fridge/freezer. My bought new 4 yr old fridge died and I didn't notice it for several days. Watery ice cubes were the 1st clue :-( That was a good fridge but it was poorly installed and I had apt AC problems for a while that also wore down the unit's compressors.Thats why I bought these two devices, so I can monitor my new fridge, track it's temps up/downs and see if I can see a correlation btw my apt ambient temp and it's internal temps.These sensors are easy to configure and set up and place! The app steps you through various config settings to allow your app to 1st find them sensors and then capture their every minute data updates via BlueTooth.Your phone needs to be near the devices for local BlueTooth access.. and these two sensors are INSIDE a metal refrigerator box .If you are a business owner or you don't WFH, you should buy their BlueTooth GW product and leave that GW in the vicinity of the devices. The GW will save all data in the Cloud and you can monitor this from the app.Since I am retired (homebody) and live in a studio apt, my phone is always close to the fridge, except when I go out. So, I get a good data most all the time.. I do leave my phone next to the fridge overnight so I always get data and use my older Android phone for my alarm clock :-)Again, if you are a professional, the GW product is the best. All the stuff I do, is done automatically by the GW and you can monitor them 24/7 around the world via internet.I did have a tech support issue but SensorPush tech support via email was very quick to help (tbh, I was surprised!) I did not expect to get everything working perfectly - as I have had a mix of bad luck with Amz tech products - but these guys came through and get me going.I am very pleased!Screen shot shows my two devices working. Whoo hoo!! :-)
