How to measure air pressure? How to measure the altitude above sea level? • It turns out that this is quite easy to do with the special BMP180 sensor. • It allows you to measure air temperature and atmospheric pressure. • Altitude is calculated by the STM32 microcontroller using a well-known formula. • The sensor is used with a ready-made strapping, namely capacitors, resistors. • The small board has 4 pins, two of which are the power supply and the other two are the I2C bus. • Let's connect to the I2C bus # 2, the connection diagram is in the video! • And then just every second we request values ??from the sensor and display them on the ST7735 display. • From the measured pressure in Pascals, we deduce the pressure in mm Hg. pillar, and also calculate the height above sea level. • • Part of the equipment: • 1) Microcontroller stm32f103c8t6, brains of the system • 2) Batteries 3.7 V 2 pcs with a switch • 3) BMP180 sensor • 4) ST7735 display 160 * 128 pixels • 5) Pulse converter LM2596S • +) Connecting wires, straight arms and a desire to figure out how everything works here • #stm32 #bmp180 #microcatchan #stm32f103c8t6 #temperature
