Circuit principle: This circuit uses BP01 type pressure sensor and op amp MAX4472. The BP01 pressure sensor is specially designed for detecting blood pressure and is mainly used in portable electronic blood pressure monitors. It is made of precision thick film ceramic chip and nylon plastic package. It features high linearity, low noise and low external stress. It adopts internal calibration and temperature compensation to improve measurement accuracy, stability and repeatability. The accuracy is ±1% and the zero offset is no more than ±300μV. The MAX4472 is a low-power amplifier chip from MAXIM that integrates four operational amplifiers. In this system, the internal integrated operational amplifier A is connected to a constant current source to provide a constant current for the pressure sensor. The operational amplifier B and the operational amplifier C form an differential input, single-ended output amplification circuit, and directly input ADC0 to monitor the blood pressure DC component.
LED DJ Display
LED DJ Booth is used different product models and structures as different conditions, which can be customized to the scene modeling. It can be spliced out the unique shape with different sizes of triangles, rectangles, hexagon. Unique DJ Table is not limited to kinds of environment. The application of the relevance and the shape of DJ LED Video Wall can enhance scene recognition.
LED Bar Display will not only present a delicate and realistic color performance through the synchronization adjustment, but also is compatible with different sources of input such as TVV, HDV, DVI, VGA, SDI. We adopt SMD technology to achieve super-wide viewing angle and better surface smoothness. Super light cabinet is to realize easy installation and maintenance that can be customized for shapes, sizes, pixels, resolution.
