HT1 SMART SENSOR: Wireless Thermometer and Hygrometer

The SensorPush HT1 Humidity and Temperature Smart Sensor with Alerts for iPhone / Android

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.

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 notwaterproof. 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.
