Previous chemical laser measurement and control system not only has huge profile

but also is inconvenient to collect data

low precision

and difficult to add more data acquisition points. So an intelligent data transmission system based on PIC MCU is designed

which is composed of remote control system and data acquisition module. This system can remotely control operation of data acquisition modules in the laser

real-timely collect and storage data of pressure or temperature

and can also wirelessly transmit data to control system. The data collection module adopts modular design

with self-powered

good scalability

which can be connected to sensors directly

without considering any changes and can be extended up to 65535. This system is mainly used in pressure measurement of chemical lasers

and can also be applied to industrial control

scientific research where large numbers of sensors are needed.
