Feature • Range: -100kPa~2.5kPa...200kPa • Gauge • Applicable for non-corrosive gas • I2C signal output, wide temperature range compensation Application • For medical fields, such as electronic sphygmomanometer, respirator, oxygen generator, monitor instrument etc. • For automotive electronics fields, such as tire gauge, EPS, brake booster, MAP sensor etc. • For sports and fitness equipment fields, such as massager, Massage chair, Air bed etc. • For other fields, such as Water heater, oxygen water machine, beer machine, coffee machine, air pump, vacuum pump, pressure meter, electric breast pump, vacuum cleaner etc. Introduction MPM7867 pressure sensor adopts the DIP package. A pressure sensor in SOP package and a signal processing chip are mounted on sides of the PCB. The sensor drift, sensitivity, temperature drift and linearity are digitally compensated through the chip, referring to the supply voltage, it gives a standard digital signal after calibration and temperature compensation. MPM7867 pressure sensor has a compact design and is easy for installation. It can be widely used in medical electronics, automotive electronics, sports and fitness equipment, etc. Specification Power Supply:(5±0.25)V DC Reference Temperature: 25°C http://www.microsensor.cn Add: No.18, Yingda Road Baoji, P.R.

Within the I2C procedure, unique situations arise which are defined as START(S)and STOP(P)conditions. When the SCL is HIGH, a HIGH to LOW transition on SDA line indicates a START condition. Data Transfers follow the format shown below. Master device sends the address(7 bits) and the data direction bit R/W of the Slaver in sequence. The addressed slaver will generate an acknowledge and pull down the SDA line in 9th period. After receiving the acknowledge of Slaver, Master shall continue to send 8 bits register address, and start another transfer or read the data after receiving an...

MPM7867 Pressure Sensor (V1.0) • Correlation between Sensor output and AD value Sensor output after calibration can be seen as actual pressure value(±1.5%Span) Note 1: Output after sensor calibration; Unit: Pa; Note 2: AD value: AD range read from the procedure(-8388608~8388607); Note 3: Sensor range: pressure difference of Up and Low limit, e.g. -100*103~200*103Pa, Full scale=Up limit -Low limit=[200- (-100) ]x103=300*103Pa, has the same unit as that of calibrated sensor output. Code Output Signal Code Accuracy Notes 1. Please make sure the measured media shall be compatible with...
