TDK InvenSense has released a new micro-electromechanical system (MEMS) barometric pressure sensor that uses an innovative capacitive MEMS architecture to deliver lower power consumption and lower noise, ideally suited for wearable fitness monitoring and battery powered IoT.
The InvenSense ICP-10125, part of the SmartPressure™ family of MEMS barometric pressure sensors by TDK, can measure height change as small as 8.5 cm, has a power consumption of 1.3 µA, a sound output of 0.4 Pa RMS and a temperature coefficient of ±0.5 Pa/°C.
Barometric pressure and a temperature sensor in a small 3.55mm x 3.55mm x 1.45mm chimney package are combined with waterproofing gel to provide IPX8 waterproofing to 10 ATM.
The uniform machined lid and chimney with groove enable easier handling at production and assembly of customer products. Aimed at the fitness, smart watch, and portable device markets, the ICP-10125 assists in fitness activity monitoring, location tracking for E911 calls, and indoor/outdoor navigation (dead-reckoning, floor/elevator/step detection).
“ICP-10125 delivers high accuracy, low power, temperature stability, and waterproofing in a small package footprint targeting the wearable market,” said Uday Mudoi, Director of Product Marketing at InvenSense, a TDK group company. “It enables determination of accurate location of E911 calls, tracks changes in elevation for activity monitoring, and extends battery life of always-on motion sensing applications.”
