Back home after his trip, he built this simple Temperature, Altitude and Pressure Display Device ... The main parts are an Arduino Pro Mini clone, a BMP180 sensor and a Nokia 5110 LCD module.

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance ... levels of resistance applied to the Velostat when the serial monitor is ...

It runs on an Arduino MEGA 2560 PRO (or similar microcontroller) and supports a wide array of additional hardware including pressure transducer, water level sensor, flow meter, OLED display ...

To that end I’m going to pick an Arduino Uno Microcontroller – admittedly ... Yes, the module works passably (see the serial monitor window) but still I’m far away from a staring pressure sensor ...
