AS200 series gas mass flow controller is suitable for a variety of conventional gases, improving the accuracy and reliability of gas mass flow control measurement results. The repeatability is as high as ±0.2%F.S.; the low leakage rate of 1×10-10 Pa·m3/sec He and good air tightness ensure production safety; it can support a variety of signal outputs, including digital signals, 1~5V analog signals and 4~20mA analog signal, can use a single power supply (+15~+24 VDC), suitable for different working scenarios; the standard open communication protocol facilitates customers to develop their own control and acquisition software; at the same time, the product also provides powerful Free client PC software to facilitate user debugging operations. AS200 series products are developed by Aosong Electronic using advanced MEMS technology. Aosong adopts unique technologies in many aspects such as sensor driving, zero-point drift control and valve control, ensuring the high performance, high quality and high reliability. AS200 is a high- quality instrument with good stability, high precision, low leakage rate and high pressure resistance.


Features:
  1. High Precision: Repeatability of ±0.2% F.S.
  2. Low Leakage Rate: Excellent air tightness for reliable performance.
  3. Versatile Output: Supports digital (RS485.
  4. Wide Power Supply Range: Operates on +15 to +24 VDC.
  5. Open Communication Protocol: Facilitates custom control software development.

Package includes: 1 x Asair AS200 GAS Mass Flow Controller, 20L/M

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
