The MS8607 triple sensor combines a pressure sensing element for barometric pressure, a sensing element for humidity and a temperature detector with integrated, digital evaluation electronics (ASIC).
The sensor is suitable for reflow soldering and designed for a pressure range of 10 to 2,000 mbar yet optimized for a pressure range of 300 to 1,200 mbar. The MS8607 measures relative humidity within a range of 0 to 100% RH and temperatures of between -40 and +85°C with great accuracy.
The measured physical variables are amplified in the ASIC and converted into 24-bit data values for pressure and temperature and into a 16-bit value for relative humidity. The data values are available as independent output signals in I²C format. The internal I2C interface is used to communicate with an external microprocessor. In a simple algorithm this links the output signals with the individual, stored correction coefficients and thus calibrates the measurements.
Triple sensor MS8607 is distinguished by its low standby current consumption of 0.24 μA max. The optimum compromise between the repeat rate and average current consumption can be individually set using the application software and thus adjusted to suit the specific application.
The MS8607 triple sensor is ideal for use in devices which require all three measurement variables and which are to be incorporated into a digital system environment. As a processor is provided at system level, this can be used for simple computation of the current pressure and temperature values.
The MS8607 comes in a QFN package (5.0 × 3.0 x 1.0 mm³).
Variants of and accessories for MS8607
The MS8607 also comes mounted by AMSYS on a circuit board as sensor module PMS8607 to facilitate the assembly of prototypes.
Another new variant is the wireless AMS 8607BLE model.
