Sensirion's SDP6x6 sensor line features especially low energy consumption, making it suitable for long-term battery operation. The SDP606 and SDP616 sensors are designed to enter sleep mode after performing each measurement. They wake up when a “measure” command is received and enter sleep mode again after completing the measurement.

The operation currents of a standard SDP600 sensor can be high as 6mA, but the new SDP6x6 sensor is optimized for operating currents no greater than 400µA. There is virtually no current drain (<1 µA) in sleep mode. This drastic reduction in power consumption allows the new sensors to be used in battery powered applications. The sensors offer a digital I2C output and are fully calibrated and temperature compensated. Thanks to the principle of calorimetric flow measurement, CMOSens differential pressure sensors achieve outstanding sensitivity and accuracy even at very low pressure differences (< 10 Pa). Furthermore, they have very high long-term stability and are free from zero-point drift. Like all devices in SDP600 series, the new sensors are available in two different versions. The SDP606 is intended for direct threaded connection to a pressure manifold with O-ring sealing, while the SDP616 is designed for tube connection.
