MEMS Sensors: China Sourcing Reference
1 resources tagged with "Mems"
MEMS (micro-electro-mechanical systems) sensors cover the piezoresistive and capacitive pressure sensors common in industrial and IoT designs, alongside accelerometers and gyros. Sourcing MEMS pressure sensors from China means weighing piezoresistive parts (good for absolute/gauge pressure, more temperature drift) against capacitive types, and confirming accuracy against IEC 61298 test conditions. IP rating and media compatibility decide whether a part survives the actual application.
When you source MEMS sensors, the headline accuracy figure means little without the temperature range and IEC 61298 test basis behind it. We check that the stated accuracy includes temperature error band, that the IP rating matches the media exposure, and that the die origin is what the datasheet claims.

FAQ
What is the difference between piezoresistive and capacitive MEMS pressure sensors?
Piezoresistive sensors change resistance with applied pressure and are simple and low-cost but show more temperature drift. Capacitive sensors measure pressure via capacitance change, generally offering better low-pressure resolution and lower power, at higher cost.
How do I verify MEMS sensor accuracy claims from a Chinese supplier?
Ask for the accuracy spec referenced to IEC 61298 test conditions including the temperature band, since a ±0.5% figure at 25°C can degrade significantly across an industrial range. Request calibration data on samples rather than relying on the datasheet typical values.
