El STS4xA de Sensirion es una serie de sensores de temperatura digitales para automóviles que se suministran en un paquete DFN. La serie actualmente ofrece dos versiones: STS41A-AD1B y STS41A-AW1B. Ambos sensores tienen calentamiento en el chip que permite el diagnóstico a bordo (OBD) y ofrece diagnósticos de función y plausibilidad en lugar de solo una verificación de presencia. Además, el modelo STS41A-AW1B puede proporcionar un empaque de flanco humectable opcional para admitir entradas ópticas automatizadas[ection (AOI).
“The expansion of our next-generation temperature sensor series means more opportunities for our customers to benefit from high precision and reliability in automotive applications. Our STS4xA temperature sensor builds on the established foundation of the STS4x sensor family, delivering a wide supply voltage range and low current consumption while maintaining top performance,” said Matthias Scharfe, product manager for humidity and temperature Sensors at Sensirion.
The STS4xA series is based on the company’s CMOSens Technology, the cost-effective device features an I2C interface for communication and supplies a wide supply voltage range. the compact sensor can be readily integrated into automotive temperature sensing applications. It also meets industry standards, such as 85C/85% RH accelerated life tests. Both the sensors come in a compact package measuring just 1.5×1.5×0.5 mm and can detect a wide range of temperatures from -40 to 125 °C with a typical temperature accuracy of 0.3 °C.
