HT1 Temperature and Humidity Smart Sensor Specification
|Dimensions||40mm x 40mm x 16.5mm / 1.57" x 1.57" x 0.65"|
|Weight||40g / 1.4oz|
|Battery Life||Typically over 1 year (more in normal conditions, less in extreme cold)|
|Compatibility||iOS 11+, Android 5.01+. Requires Bluetooth 4.0+ (also known as Bluetooth LE).
iPhones since the iPhone 4s, iPads since the 3rd generation and the 5th generation iPad Touch support this technology.
There are too many Android devices to list them all here, but you can look in the specifications for your device for Bluetooth 4.0 or Bluetooth LE. Please contact SensorPush support if you are unsure about your specific device.
|Temperature Range||-40°C to 60°C (-40°F to 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)
(0°C - 60°C / 32°F - 140°F)
|±0.3°C / ±0.5°F typical ±0.5°C / ±0.9°F maximum|
|±0.7°C / ±1.3°F typical 1.2°C / ±2.2°F max|
(@ 25°C / 77°F, from 20% - 80% RH )
|±3% typical ±4.5% maximum|
(@ 25°C / 77°F, from 0% - 100% RH )
|±4.5% typical ±7.5% maximum|
|Accuracy Notes||95% of sensors fall within the "typical" range. Sensors outside the "maximum" range are not qualified for sale.
Please note that above values are maximal tolerances (not including hysteresis) against a high precision reference such as a dew point mirror. Common deviations are within ±2%RH where specified tolerance is ±3%RH and about half the specified tolerance at other values.
