Wireless Relative Air Pressure Sensor with syringe

I. Working Principle
The main sensing element of the relative air pressure sensor is a pressure-sensitive thin film connected to a flexible resistor. When the pressure of the measured gas decreases or increases, the thin film deforms, causing the resistance of the resistor to change. As the resistance changes, the voltage measured across the resistor also varies. This voltage is then converted via A/D conversion and received by a data acquisition unit, which transmits the results to a computer in an appropriate format.

IV. Typical Applications
The relative air pressure sensor can measure the pressure of containers and ambient environments. It is primarily suitable for physics experiments related to gas pressure, such as gas laws, and can also measure dry, non-corrosive gas pressure in biological and chemical experiments. Typical applications include:
– Atmospheric pressure measurement
– Ideal gas law experiments
V. Note
This product is intended solely for educational use and is not suitable for industrial, medical, research, or commercial applications.
VI. Usage Tips
1. Ensure the container of the measured gas is tightly connected to the sensor’s pressure port via the tubing during use.
2. Do not use for measuring liquid pressure, and avoid exceeding the specified range.
