My Arduino projects
This is a working repository for arduino projects
#vac-chamber-controller Vacuum Chamber Controller Mk1.
Incorporates LCD display, BMP280 sensor, rotary encoder and switch, vacuum pump relay and solenoid control circuits.
BMP280 reads pressure and temperature. LCD screen displays pressure and temp. Shows remaining time during vacuum cycle Rotary encoder allows selection of vacuum pressure and timer lenghth. Switch starts pump cycle Timer begins when target pressure is achieved Pressure released when timer elapsed or cycle ended with switch
#hydro-clime Hydroponic Climate Monitor and Controller
BMP280 Atmospheric pressure and temperature DHT11/22 Ambient temperature and humdity
Controls climate making use of aircon/dehumidifier, extractor fans, and heaters.
