Highly accurate measurement, broad range of applications
The stated accuracy of the relative humidity measurement up to ±1.8 % (incl. 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 125 °C, the HTE301 sensing element is suitable for a wide range of applications.
Suitable for demanding operating conditions
The active sensor surface is permanently protected against dirt and corrosive deposits by the proprietary E+E sensor coating. 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.
The integrated constant current heater, which can be activated as required, keeps the sensing element at an excess temperature and thus prevents condensation and deposits caused by condensation.
Measured value output via I²C interface
The measured value output is based on the I²C data communication protocol. The measured values are available in 16 bit unsigned integer format. 4 individually adjustable I²C addresses make it possible to operate several sensing elements on one I²C bus.
Simple design-in and evaluation kit
The DFN enclosure of the HTE301 measures only 2.5 x 2.5 x 0.9 mm. This makes the sensing element suitable for demanding designs and tight spaces.
