Description
This project was the brain of a calorimeter for a chemistry experiment. Features: Arduino ProMini mounting point to control various features including a Stop watch with LCD display Barometer/altimeter (air pressure) Thermistor (Temperature probe) Secondary temperature probe 555 driven mosfet to control motor speed with pwm signal Humidity sensor Calibration trimmer Breakouts for some of the Arduino pins Buck converter for the 3.3V sensor Breakouts for the I2C This is just the hardware but must be supported with the code to enable the hardware at the software level. Could also be used as a weather station.
