In this particular example we are going to simply display temperature, pressure and altitude readings from a MS5611 sensor on an OLED display. We will be using various Wemos MIni shields and an MS5611 sensor

Here is a little about the MS5611

This barometric pressure sensor is optimized for altimeters and variometers with an altitude resolution of 10 cm. The sensor module includes a high linearity pressure sensor and an ultra-low power 24 bit ΔΣ ADC with internal factory calibrated coefficients. It provides a precise digital 24 Bit pressure and temperature value and different operation modes that allow the user to optimize for conversion speed and current consumption. A high resolution temperature output allows the implementation of an altimeter/thermometer function without any additional sensor. The MS5611-01BA can be interfaced to virtually any microcontroller. The communication protocol is simple, without the need of programming internal registers in the device.

This is the module we used which makes it easy to use the sensor

Parts List

1 x Wemos Mini
1 x Wemos Dual Base
1 x OLED Shield
1 x MS5611 sensor (GY-63)

I connect the Wemos Mini to the dual base and then put the OLED shield along side this, I then connect the Ms5611 sensor to the Wemos Mini using cables.
