The BME21M621 is a gauge pressure sensor module that composed of gauge pressure sensor module, the BM62S2201-1, and a breakout board. It includes 24-bit ADC and has been calibrated at factory.
The BME21M621 has the same functions and specifications as the gauge pressure sensor module, BM62S2201-1. The difference between them is that the BME21M621 breaks out the BM62S2201-1’s pins to match the BMCOM connectors, and can directly connect to BMduino development boards, such as BM53A367A.
You can use the product with Arduino development boards, such as Arduino UNO, as well.
The built-in BM62S2201-1 on the BME21M621 is a gauge pressure sensor module that includes temperature compensation function and is used to measure the pressure of gas or liquid relative to the ambient atmospheric pressure at the same location.
