Expanded sensing element series for humidity and temperature

E+E Elektronik has expanded its digital sensing element portfolio with two new product variants. The HTE301 humidity and temperature sensing element and the TEE301 temperature sensing element provide outstanding measurement accuracy and a wide application temperature range from -40C to 125C (-40F to 257F). The small 8-pin DFN package with its I2C interface and four individually configurable I2C addresses is excellent for state-of-the-art, demanding designs.

The sensing elements are part of the new sensing element generation by the company. Presenting the same accuracy values, they are cost-optimised variants of the HTE and TEE501 sensing elements introduced previously. With a different data format (16-bit unsigned integer) and pin assignment compared to the 501 series, the 301 series provides easy upgrade of current applications with minimal integration effort.

The HTE301 sensing element offers a measurement accuracy of up to ±1.8% RH (incl. hysteresis) and ±0.2C. It provides an integrated constant current heater which maintains the element at approximately 2-3C over-temperature and stops condensation forming on the sensing element. This results in exceptional measurement performance and fast response time, even in conditions with high humidity. Also, the proprietary E+E sensor coating shields the active sensor surface of the device against contamination and corrosive deposits.

The TEE301 sensing element measures the temperature with an accuracy of up to ±0.2C. Thanks to its wide temperature range, the sensing element is versatile, offering a reliable and cost-effective solution for demanding temperature measurement tasks.

These sensing elements are offered as an 8-pin DFN package with dimensions of only 2.5mm x 2.5mm x 0.9mm3 to support easy integration into existing applications. The I2C interface allows robust data communication, supporting communication speeds up to 1,000kHz. The sensing elements provides four selectable I2C addresses and alert and reset functions.
