When 0V or GND is applied to the right pin, 0V or GND appears on the left pin. For logic 0 levels, when 0V or GND is applied to the left pin, 0V or GND appears on the right pin.Ĭonversely, when 5V is applied to the right pin, 3.3V appears on the left pin. In the above circuit, for logic 1 levels, when 3.3V is applied to the left 3.3V_Logic pin, 5V appears on the right 5V_Logic pin. Transistor Bidirectional Level Shifter 2N7000 Bidirectional Level Shifter Power for the pressure sensor module must be taken from the Arduino 3.3V pin.Īlternatively a transistor such as a 2N7000 N-Channel MOSFET can be used to make a bidirectional level shifter as shown below. Arduino Due GY-BMP280-3.3 Pressure Sensor Module I☬ Wiring Diagram I☬ Wiring to 5V Arduino UnoĪ bidirectional level shifter module can be used to connect the 3.3V GY-BMP280-3.3 module I☬ pins to a 5V Arduino such as an Arduino Uno or Arduino MEGA.
Module pin 3 to Arduino Due SCL (pin 21).I☬ Wiring to 3.3V Arduino DueĪ GY-BMP280-3.3 pressure sensor module can be used directly with a 3.3V Arduino such as an Arduino Due. Specific Arduino pins must be used for hardware SPI. Hardware SPI refers to using the actual hardware SPI device of the microcontroller chip on the Arduino. This enables a SPI device such as the pressure sensor to be connected to any Arduino pins.

How to wire the module to 3.3V and 5V systems is shown below with examples using an Arduino Due and Arduino Uno. The easiest way to operate it is to use it with a 3.3V Arduino such as an Arduino Due, Arduino Zero or Arduino M0. Unlike some other modules that use the same BMP280 sensor, this module does not have a voltage regulator or level shifters for easy use with 5V systems. The video below shows an Arduino Due running the test sketch and displaying pressure, altitude and temperature.Ĭan't see the video?

This tutorial shows first use and testing of the GY-BMP280-3.3 pressure sensor module so that you will know whether the device is working or not. Also see the GY-BMP280-3.3 pressure sensor module pinout for pin numbering and circuit diagram of the module pictured below. It contains a BMP280 sensor from Bosch that can measure both atmospheric pressure as well as temperature. The image below shows the pressure sensor module used in this tutorial.

This is easily done as the library can be installed from within the Arduino IDE without the need for a complicated manual installation. To use the pressure sensor module, a library must be installed in the Arduino IDE.
The module operates from 3.3V and is not 5V tolerant, so it is important to wire it correctly to 5V Arduinos using level shifters and 3.3V for power. Either I☬ or SPI interfaces can be used to connect the module to Arduino.
