Description M5Stack Tube Air Pressure Unit is a compact positive and negative pressure gauge built for tubing-based gas sensing, pneumatic experiments, and embedded control systems. As an air pressure measurement sensor, it supports a wide working range of -100 ~ 200Kpa and converts pressure into a proportional 0.1 ~ 3.1V signal. That behavior makes the unit useful for industrial gas pressure detection, pressure verification, and host devices that need direct analog pressure output instead of a more complex digital interface. Features The module works as a positive and negative pressure gauge for gas measurement systems and pneumatic fixtures. This air pressure measurement sensor covers a pressure range from -100 ~ 200Kpa. The module provides stable analog pressure output from 0.1 ~ 3.1V for direct acquisition or control logic. A protected housing and Grove interface make installation simple in compact equipment or benchtop rigs. It is well suited to industrial gas pressure detection, equipment tubing tests, and vacuum-side pressure checks. Specifications Sensor Model MCP-H10-B200KPPN Measurement Medium Gas Positive & Negative Range -100 ~ 200Kpa Proportional Output 0.1 ~ 3.1V Accuracy ±1.5Kpa (0 ~ 85°C) Supply Voltage 5V Product Size 32.0 x 24.0 x 12.5mm Product Weight 4.6g Package Size 138.0 x 93.0 x 13.5mm Gross Weight 10.0g Applications This air pressure measurement sensor is designed for industrial gas pressure detection, equipment air pressure measurement, laboratory pressure verification, and control loops that rely on analog pressure output. Because this positive and negative pressure gauge handles both vacuum-side and pressure-side readings, it also works well in pneumatic diagnostics, leak checking, and compact automation fixtures. Product List 1 x Tube Air Pressure Unit 1 x HY2.0-4P Grove Cable (20cm) Other Content The unit uses the sensor model MCP-H10-B200KPPN and maps pressure to voltage so that host systems can read it with standard analog acquisition methods. This makes the module useful when a simple air pressure measurement sensor and predictable analog pressure output are preferable to a more complex digital pressure interface, especially in industrial gas pressure detection setups.
