TE Connectivity (TE) has introduced the MS8607-02BA01, a digital system- in-package which senses pressure, humidity and temperature.

Factory-calibrated and measuring just 5mm x 3mm x 1mm, the MS8607 may be used with any microcontroller that has an I2C interface.

The sensor is notable for its low power consumption and high accuracy. In stand-by mode, the sensor draws just 30nA. The peak supply current during a pressure or temperature conversion is 1.25mA.

TE’s MS8607 contains two sensors based on two different MEMS technologies. The first sensor is a piezo-resistive sensor measuring pressure and temperature.

The second sensor is a capacitive sensor measuring relative humidity. Each sensor is interfaced to a delta-sigma ADC for conversion to a digital value. The MS8607 converts both analogue output voltages to a 24-bit digital value for the pressure and temperature measurements, and a 12-bit digital value for the relative humidity measurement.
