However, it's great for basic barometric pressure sensing. The sensor is soldered onto a PCB with 10K pull-up resistors on the I2C pins.\u003c\/p\u003e\n\u003cp\u003eThis chip is good for use with power and logic voltages ranging from 2.4V to 5.5V so you can use it with your 3V or 5V microcontroller. There's a basic temperature sensor inside but there's no specifications in the datasheet so we're not sure how accurate it is.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis chip looks and sounds a whole lot like the \u003ca href=\"\/en-eu\/products\/adafruit-mpl3115a2-i2c-barometric-pressure-altitude-temperature-sensor\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eMPL3115A2\u003c\/a\u003e but this is the less precise version, best for barometric sensing only\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUsing the sensor is easy.
