Product Introduction：
Air pressure sensor adopts imported high precision measuring unit. Built-in high precision temperature compensation, high stability, small drift, high repeatability. It can be easily attached to the wall via a wall-mounted enclosure. It is suitable for small weather stations where air pressure monitoring and temperature measurement are needed. This product can accurately measure the atmospheric pressure value, suitable for pressure measurement in various environments. This product adopts the original imported sensors, the measurement data is stable, high precision, anti-interference ability, long service life and so on. It can be widely used in environmental computer room, airport, railway station, commercial building control, family residence, office building, school, conference room, business market, hotel, gymnasium, cinema, library and other fields, it has a broad application prospect.

FAQs：
Air pressure sensor cannot be connected to PLC or computer
Possible causes:
1, the computer has more than one COM port, select the wrong port.
2, air pressure sensor address is not correct, or there is a duplicate device address (all factory default is 1).
3, baud rate, check mode, data bit, stop bit error.
4. The host polling interval and waiting response time are too short. Set them to more than 200ms.
5. The 485 bus is disconnected, or the A and B wires are connected in reverse.
6, if the number of air pressure sensor is too much or the connection is too long, should be the nearest power supply, add 485 intensifier, increase the resistance of 120Ω end.
7. The USB to 485 driver is not installed or damaged.
8. Equipment damage.
