  • Temperature


The digital temperature sensing element TEE301 is the next generation of the series TEEx01. With a 16-bit unsigned integer value and a different pin assignment compared to TEE501, the TEE301 allows an easy upgrade for your existing application with minimal integration effort.

    Highly accurate and versatile
    The sensing element is suitable for temperature measurement in a working range from -40 °C to 125 °C. The factory multi-point temperature adjustment ensures excellent measurement accuracy of up to ±0.2 °C. The outstanding measuring performance and reproducibility makes the sensing element the perfect solution for demanding measuring tasks.

    Easy-to-integrate DFN housing
    The small dual flat no-leads (DFN) housing has a footprint of only 2.5 x 2.5 mm² and can therefore be integrated into almost any application.  The sensing element requires a supply voltage of 2.35 - 3.60 V for operation.

    Data communication via I²C interface
    The I²C interface ensures interference-free data communication with the TEE301 and supports communication speeds of 100 / 400 / 1000 kHz. The measured values are available in 16-bit unsigned integer format. Robust I²C interface communication is ensured by a checksum and glitch suppression.
    4 individually adjustable I²C addresses make it possible to operate up to 4 sensing elements on one I²C bus.
