The HTM502 sensing module by Austrian sensor manufacturer E+E Elektronik offers a cost-effective solution for humidity and temperature measurement. It is characterized by easy implementation, high accuracy, and reliability. Integration and interchangeability via the I2C interface allow for rapid project implementation. The integrated sensor protection and the mechanically robust enclosure support a wide range of applications. The module is particularly suitable for price-sensitive applications in the HVAC sector but also for industrial applications. Great mechanical stability The HTM502 sensing module measures humidity and temperature with an accuracy of ±2.0% RH and ±0.3 °C (0.54 °F) and can be used in applications between 5 °C and 60 °C (41...140 °F). The robust enclosure gives the module great mechanical stability and ensures ease of handling by preventing accidental contact with the sensing element. The integrated E+E sensor coating protects the sensing element against dirt and corrosion The integrated E+E sensor coating protects the sensing element against dirt and corrosion, improving measurement performance and long-term stability in harsh and demanding environments. The I2C interface allows for easy integration of the humidity and temperature module, meaning that projects can be quickly implemented. Measurement operating modes The HTM502 offers two measurement operating modes (single-shot or periodic measurement mode) and supports communication speeds up to 1000 kHz. Thanks to the low supply voltage of 2.35 – 3.60 V and the low current requirement, the module is also suitable for applications with low energy consumption. The HTM502's design lends itself to easy installation without additional implementation overhead or soldering work. Thanks to the 4-pin connector plug, the sensing module can quickly be replaced in the field.

Austrian sensor manufacturer - E+E Elektronik is expanding its digital sensing element portfolio to include two new product variants. The HTE301 humidity and temperature sensing element and the TEE301 temperature sensing element offer excellent measurement accuracy and a wide application temperature range from -40 °C to 125 °C (-40 °F to 257 °F). The small 8-pin DFN package with its I2C interface and four individually configurable I2C addresses is ideal for state-of-the-art, demanding designs. HTE and TEE301 sensing elements The HTE and TEE301 sensing elements are part of the new sensing element generation by E+E Elektronik The HTE and TEE301 sensing elements are part of the new sensing element generation by E+E Elektronik. Offering the same accuracy values, they are cost-optimized variants of the HTE and TEE501 sensing elements introduced earlier in 2022. With a different data format (16-bit unsigned integer) and pin assignment compared to the 501 series, the 301 series allows easy upgrade of existing applications with minimal integration effort. HTE301 humidity and temperature sensing element The HTE301 sensing element impresses with a measurement accuracy of up to ±1.8% RH (incl. hysteresis) and ±0.2 °C. It features an integrated constant current heater which keeps the element at approx. 2-3 °C over-temperature and prevents condensation forming on the sensing element. This results in excellent measurement performance and fast response time, even in conditions with high humidity. On top of this, the proprietary E+E sensor coating protects the active sensor surface of the HTE301 against contamination and corrosive deposits. TEE301 temperature sensing element The TEE301 sensing element measures the temperature with an accuracy of up to ±0.2 °C. Thanks to its wide temperature range, the sensing element is versatile, providing a reliable and cost-effective solution for demanding temperature measurement tasks. DFN package with I2C interface Both sensing elements are available as an 8-pin DFN package with dimensions of just 2.5 x 2.5 x 0.9 cubic millimeters to support easy integration into existing applications. The I2C interface enables robust data communication, supporting communication speeds up to 1,000 kHz. The sensing elements offer four selectable I2C addresses, as well as alert and reset functions.

With the Humidity Calculator by E+E Elektronik, complex humidity calculations can be performed easily and in real-time. This free calculation tool works online in any recent browser and can also be installed as an app on smartphones or a PC. Up to 15 humidity-related parameters can be computed with the practical calculation program. In addition, the E+E Humidity Calculator features a separate calculation mode for determining the pressure dew point. Humidity calculation including measurement uncertainty The E+E Humidity Calculator also takes the measurement uncertainty into account Based on three known physical quantities (pressure, temperature, and humidity measures), the E+E Humidity Calculator computes up to 15 humidity-related parameters such as the dew point, frost point, absolute humidity, enthalpy, etc. A significant difference to other humidity calculators is that the E+E Humidity Calculator also takes the measurement uncertainty into account and therefore, ensures particularly practical results. Simulate the behavior of the humidity values In addition to computing and converting physical humidity quantities, the E+E Humidity Calculator can also be used to simulate the behavior of the humidity values as pressure and temperature conditions change. For realistic calculations, air and 10 other gases (including argon, CO2, helium, and methane) can be selected as the carrier medium. The formulae for conversion, including computing the uncertainty, are based on the common humidity theories and have been validated by the accredited E+E Elektronik calibration laboratory. Practical dew point calculator E+E Humidity Calculator features a separate calculation mode for computing the dew point In addition to calculating the humidity, the E+E Humidity Calculator features a separate calculation mode for computing the dew point in compressed air systems. This makes it easy to determine the change in dew point temperature in relation to the gas pressure. User-friendly and functional device The E+E Humidity Calculator is easy and intuitive in use, and it offers a rich set of useful features. For example, the measurement units of the physical quantities can be converted from SI to the US system of units with just one click, or individually defined for each physical quantity. Users can adapt the list of calculated physical quantities to suit their own needs by displaying or hiding individual lines. The computation results can be exported as PDF or Excel files and also sent via e-mail. A click on the Reset button clears all calculations and restores the initial list of measures.
