General Sensor for Pressure Monitoring Systems (PMS)

The SP27 sensor is designed for measuring pressure in PMS applications. With its microcontroller and integrated peripherals, the SP27 is a single package solution, requiring very few external components.
Pressure and temperature measurements are controlled by software. The microcontroller formats and processes the measured data and passes them to the PMS. An intelligent wake-up mechanism reduces power consumption, while an interval timer controls the timing of measurements. The circuitry can be programmed to wake up at regular intervals. An external wakeup source can also be connected to a general purpose input/output (GPIO) interface.
