Altitude click features the MPL3115A2 MEMS pressure sensor, which provides accurate pressure/altitude (20-bit) and temperature (12-bit) data. Resolution is down to 30 cm (1.5 Pa). The MPL3115A2 contains automatic internal data processing with data acquisition and compensation. It features a 32 sample FIFO buffer to minimize the overhead of collecting multiple data samples. It can autonomously collect data at programmed intervals and store it up to 12 days depending on data acquisition rate (1 second - 9 hours). The board uses an I2C communication interface and is designed to use a 3.3V power supply only. |

Pressure Click is a compact and easy solution for adding pressure measurement to your design. It features the LPS331AP digital output pressure sensor. The LPS331AP IC is an ultra compact absolute piezoresistive pressure sensor capable of measuring pressure (260-1260 mbar) or temperature (-40°C to 80°C) and provides a digital signal output to your microcontroller. Pressure Click communicates with the target board microcontroller via mikroBUS SPI (MOSI, MISO, SCK, CS), I2C (SDA, SCL) and INT lines. The board is designed to use a 3.3V power supply only. |

Pressure 2 click carries an MS5803, a high resolution MEMS pressure sensor that is both precise and robust. Its measurement range is from 0 to 14 bars (with a resolution of up to 0.2 mbars), but because of the stainless steel cap enclosure, the sensor can withstand up to 30 bars of pressure. Pressure 2 click communicates with the target board MCU either through mikroBUS SPI or I2C lines, depending on the position in which the onboard jumpers are soldered. |

Barometer click carries the LPS25HB IC, which is a piezoresistive absolute pressure sensor with a measurement range from 260 to 1260 hPa (with a 24-bit resolution output). It's a high precision sensor and high resolution mode it can measure pressure within 0.01 hPa RMS. A low resolution mode can be implemented to reduce power consumption. Barometer click can communicate with the target board MCU either through I2C or SPI pins (which is specified by soldering onboard jumpers in appropriate position). An interrupt pin is also available, which can be configured either as Data Ready (sends signal when pressure value changes) or as a threshold trigger (sends signal when specified high or low pressure value is reached). The board uses a 3.3V power supply only. |

Pressure 3 click is a mikroBUS add-on board that carries an Infineon DPS310 digital barometric pressure sensor. It has an operating range from 300 to 1200 hPa with a relative accuracy of 0.06 hPa and absolute accuracy of 1 hPa. DPS310 is a fast sensor with typical measurement time of 27.6 ms for standard mode, down to 3.6 ms in low precision mode.
The digital measurements are in 24-bit resolution. Up to 32 results can be stored in a FIFO buffer.
Pressure 3 click has both I2C and SPI outputs. The four interface configuration buttons are soldered to mikroBUS I2C pins by default. The click uses a 3.3V power supply. |
