The circuit uses BP01-type pressure sensor and amplifier MAX4472. BP01-type pressure sensor is specifically designed for the detection of blood pressure, and is mainly used for portable electronic device.It uses precision thick-film ceramic chip and nylon plastic packaging,it has the characteristics of a high linear, low noise and external stress of small;it uses the internal calibration and temperature compensation mode to improve the measurement accuracy, stability and repeatability, in the whole range,the precision is ± 1%, zero offset is not greater than ± 300μV.MAX4472 is the MAXIM company's a low power consumption chip which integrates four operational amplifiers.
