“A simple humidity, temperature, and pressure data logger.
Arduino Pro Mini 5V 16MHz
SD card module
RTC module with battery
RJ11 socket (optional)
BMP180 pressure sensor (preferably with a 5V input power option on a breakout board)
SHT31-D humidity sensor
24 X 4 LCD module with I2C interface
3 small push buttons
Lots of little wires
and also a usb to serial adaptor to program the arduino.
Why I Made It
I wanted to be able to view live atmospheric information and also log it for looking at it in a graph whenever I want. Simply
I have not included a case in this project as I’m sure people will know what the best case for them selves is.
I started by soldering all the components onto a strip board like so I thought we be most efficient.”
