The product is an air velocity module composed of a breakout board and the MEMS-type air velocity sensor BM62S2301-1, which provides a 12-bit resolution digital output.
It incorporates “solid” thermal isolation technology and a silicon carbide coating, offering protection from abrasive wear and water condensation. It is suitable for applications such as air filtration systems and blockage detection systems.
The product has the same functionality as BM62S2301-1. The difference between them is that the product breaks out the BM62S2301-1’s pins to match BMCOM connectors and can directly connect to BMduino development boards, such as BM53A367A or BM18B367A.
You can use the product with other development boards, such as Arduino UNO, as well.
Similar products on the market are generally divided into velocity type and flow type. The product is a velocity type, using a heater and two thermopiles for measurement. It is suitable for measuring air/gas velocity in open environments. Flow-type products are primarily used to measure the flow of liquid or gas through a pipeline, typically expressed in volume or mass.
Measurement Output
The product offers two output modes:
Air Velocity Output Mode: Directly converts the A/D value to the air velocity value for output, which is very convenient!
Raw Value Output Mode: Simultaneously outputs both the A/D value and the air velocity value.
The product continuously senses after being powered on and only outputs data upon receiving a command.
⬥ Refer to the "Output Curve" section on page 6 of the BM62S2301-1 datasheet for more details.
