数字湿度和温度感应元件
HTE501
新一代数字RH/T传感器兼具精确性和可靠性,能够满足当前和未来的最高要求。集成恒流加热器以及创新且久经考验的E+E专有涂层,即使在恶劣的环境中也能确保卓越的性能。HTE501采用DFN封装,尺寸仅为2.5 x 2.5 mm,可提供高达±1.8%RH(含滞后)的卓越精度,并具有露点计算功能,一个I2C接口最多可连接8个设备。此外,该传感器的工作温度范围为-40至+135°C,湿度范围为0至100%RH,能够满足各种苛刻的应用需求。
High level of measurement accuracy, wide 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 135 °C, the HTE501 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.
Direct 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 integer format and can be processed directly. In addition to the humidity and temperature values, the dew point is also calculated and output directly. 8 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 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.
