Fermion ICP-10111 Pressure Sensor (Breakout) DFRobot Fermion ICP-10111 Pressure Sensor (Breakout) is a barometric pressure temperature sensor equipped with TDK's ICP-10111 sensor. The sensor is based on MEMS capacitor technology to achieve ultra-low power consumption, industry-leading relative accuracy, and temperature offset coefficient. The Fermion ICP-10111 barometric pressure temperature sensor can measure the pressure difference with an accuracy of ±1Pa, an accuracy enabling altitude measurement differentials as small as 8.5cm.
