Data Format of One Sampling Cycle The master sends START command to the slave sensor, when the slave sensor has received the START command, the slave will start the sampling function, the master should be waiting for the sampling hold time (tACQ) during the slave sensor sampling function, then the slave sensor will send back the each channel’s data from CH1 to CH6.

 The sensor contains a permanent magnet, it will cause the recordable magnetic media damaged, such as cassette tapes, floppy disks, credit cards, hard drives, keep it away from such types of magnetic media.  To avoid the ferromagnetic particles being collected from a dirty environment.  Magnets tend to snap to each other or the magnetic metals, be careful when handling the sensor not to apply mechanical shock, otherwise the sensors might be abnormal or break.  Do not place the sensor near the person who has an electronic medical device. It is very dangerous and may cause malfunction of an electronic medical device.  Magnetic devices may be subject to special transport regulations.  To avoid the abrasion of the sensor’s metal case or stuck the banknote, about 0.1mm gap between the sensor and the opposite side such as rollers is recommended to reduce the pressure of the sensor’s metal case.  To avoid excessive force on terminals, please mount the sensor’s base firmly on the PCB and solder all the terminals.  Hand soldering should be applied, the soldering temperature should be 350±10oC less than 3 seconds or 260±5oC less than 10 seconds
