Description
Module with a digital barometer to measure the height in metres, and pressure in the range of 500 to 1150 hPa. Data is sent to the microcontroller via the I2C bus (TWI) with an accuracy of up to 1.5 hPa in the case of measuring pressure or 50 m for height. The sensor operates with voltages in the range of 3.0 V to 5V. It can be used directly by the microcontrollers, operating at these voltages, for example,Arduino Uno.
Pins
Pins are the holes for soldering the goldpin connectors of 2.54 mm raster (strap is in the set) to connect the module with thewiresor to directly attached to the breadboard.
| Pin | Description |
|---|---|
| VDD | Supply voltage from 2.5 V to 5.0 V |
| GND | The ground of the system. |
| SDWN | Standby mode is activated with the low status. |
| RST | The system's reset is activated with the low status. |
| SDA | The data line of the I2C bus. |
| SCL | Clock line of the I2C bus. |
