![]() ![]() ![]() The second mode is automatic control while running it we can set on and off values on which each relay can be on or off according to the current values of temperature and humidity. The first mode is Manuel control while running it we can control the relays on and off manually from Manuel control page. The Raspberry Pi has two mode to control 4 relays which can drive motors according to the current values of temperature and humidity : The measured values stored are displayed in plot chart with time during the day to give live monitoring of humidity and temperature measurements, also The current instantaneous values of temperature and humidity are also displayed and updated every 6 seconds. We will get the values of temperature and humidity measured by DHT11 sensor and store these values every minute in log file in data base daily which cleared at the end of the day. In this post we will read the measured values of temperature and humidity from DHT11 sensor and display the measurements daily in plot graph and also control relays to switch off and on according to theses live measurements and setting values the user can submit using GUI display connected to Raspberry Pi. Temperature & Humidity display and control using Raspberry Pi ![]()
