Bosch barometric pressure sensorBosch has launched the SMP580, a new barometric pressure sensor for ambient pressure and temperature measurement in automotive engine management applications. The company claims the SMP580 is the smallest sensor of its type available on the market - measuring 4.9 x 3.9 x 1.5mm³.

According to Bosch the new sensor delivers high measurement accuracy and long term stability, with a 12-bit digital SPI interface for pressure and temperature readings. Over the sensor’s lifetime the company claims pressure readings are accurate to a tolerance of less than 1.0kPa, and temperature to less than 3 K. The sensor has low power consumption, with a supply current of less than 5mA.
