U130 · M5Stack
Unit Tube Pressure is a positive and negative pressure gauge that supports a wide measurement range from -100 ~ 200Kpa. During use, the device connects via a tube, with the other side linked to the gas measurement environment. The sensor proportionally maps -100 ~ 200Kpa to an output voltage of 0.1 ~ 3.1V. It comes with a full-coverage protective housing to ensure stable operation of the sensor, making it ideal for applications such as gas pressure detection in industrial equipment.
