1. The flowmeter is running normally, but data cannot be transmitted to the computer. The reason why the flowmeter is running normally but data cannot be transmitted to the computer may be due to hardware connection problems or computer settings issues. Hardware connection issue: Data cable damaged or poorly connected: Check and replace the data cable to ensure good connection and no damage to the data cable. This is the basic step in solving data transmission problems, as damaged data cables or poor connections can cause signals to not be transmitted stably. Wireless transmission obstacles: If using wireless devices (such as Bluetooth or infrared) for data transmission, check if the transmission distance is too far and if there are any obstacles blocking it. These factors may all affect the stability and transmission quality of wireless signals. Computer setup issue: Driver issue: The computer requires the correct driver to recognize and communicate with the flow meter. If the driver program is missing, outdated, or damaged, the computer will not be able to receive data from traffic sources such as traffic sensors. Therefore, updating or reinstalling the computers drivers is the key to solving this problem. Security software blocking: Sometimes, security software may mistakenly identify data transmission as a potential threat and block it. To test this, you can try temporarily disabling security software to see if it can solve the problem. DNS settings issue: If there are problems with the computers network DNS settings, it may also result in data being unable to be uploaded. Checking and fixing DNS settings, or restarting the router, may help resolve this issue. If none of the above methods can solve the problem, it is recommended to contact professional technicians for further investigation and repair to ensure that the flowmeter can transmit data to the computer normally.

2. Is there any app on the phone that can count the number of people entering the supermarket?

1. Hand hail swimming counting can be done using the "Counter" app. Users need to manually click to increase the number of people, suitable for simple counting needs

2. There is no APP that can automatically identify and count before sales, and more advanced technical support is needed

3. There are small infrared passenger flow statistical devices on the market, such as the "mall store flow meter, material distribution analyzer, two-way infrared passenger flow statistical device", which can automatically count the flow of people.

3. Radar open channel flowmeter

4. Is there any mobile app that can count the number of people entering the supermarket?

?

1. If you want to manually count, you can use the "Counter" app. Users need to manually click to increase the number of people, suitable for simple cumulative counting

2. Currently, mobile apps cannot achieve automatic recognition and counting functions, as this usually requires more advanced technical support
