The digital humidity and temperature sensing element - HTE501 from E+E Elektronik offers an excellent measurement accuracy of up to ±1.8 % RH incl. hysteresis and ±0.2 °C. The proven E+E sensor coating and the integrated constant current heater ensure a high level of reliability and durability of the sensing element even in harsh, dirty and condensing environments.
The DFN enclosure, which measures just 2.5 x 2.5 x 0.9 mm, and the I2C interface enable simple design-in. The sensing element's diverse applications range from industrial and facility automation to medical technology, household electronics, smart and wearable devices.
High level of measurement accuracy, varied applications
The stated accuracy of the relative humidity measurement of up to ±1.8 % includes hysteresis
The HTE501’s high level of measurement accuracy is the result of the Austrian sensor specialist's more than 30 years of experience in the field of humidity measurement technology and the use of state-of-the-art manufacturing technologies.
The stated accuracy of the relative humidity measurement of up to ±1.8 % includes hysteresis. Integrated hysteresis compensation ensures that the sensing element always keeps within its tolerance window, even when the humidity content rises or falls.
With a temperature range of -40 °C to 135 °C, the HTE501 sensing element is suitable for a wide range of applications.
Suitable for demanding operating conditions
The HTE501’s active sensor surface is permanently protected against dirt and corrosive deposits by the proprietary E+E sensor coating, which has proven itself over many years.
Originally developed for industrial applications, this special protective coating ensures excellent measurement performance and long-term stability even under demanding conditions. The sensing element can, therefore, be used in harsh environments without the need for additional protection options, such as a membrane filter or filter caps.
The integrated constant current heater, which can be activated as required, keeps the sensing element at excess temperature and thus prevents condensation and deposits caused by condensation.
Direct measured value output via I2C interface
The measured value output is based on the I2C data communication protocol
The measured value output is based on the I2C data communication protocol. The measured values are available in 16-bit integer format and can be processed directly.
In addition to the humidity and temperature values, the dew point is also calculated and output directly.
It is not necessary to convert the measured values. 8 individually adjustable I2C addresses make it possible to operate several sensing elements on one I2C bus.
Simple design-in
The DFN enclosure of the HTE501 measures only 2.5 x 2.5 x 0.9 mm. This makes the sensing element suitable for demanding designs and tight spaces. The integrated I2C pull-up resistors further facilitate design-in, as no external circuitry is required.
