Hi, I’m a student and I am on a project now. It is a rain detector project. Inputs are Temperature sensor, Humidity sensor, and Rain sensor. Temperature and humidity level will display on LCD. Outputs are a LED and Servo motor. After the rain sensor detects water on it , and considering certain level of temperature and humidity level, the LED and servo motor will get triggered for and outcome action. IAs per my idea, i would like to use Rain sensor module, DHT11 sensor, mini servo motor, LCD display screen, LED and Arduino Uno R3. Let me know if anyone can give a hand for my project, it would be very helpful for me. Thanks in advance.
You’ve got data coming in, and so the first stage needs to be decision-making, changing that into information in variables. Stage 2 responds to the information, displaying it or switching things off-board. When doing anything off-board, make the last stage an opto-isolator. Don’t forget pins usually need to be declared as data in or out.
Also, include timer circuits to stop flooding the conservatory. A nice extra would be power management software, monitoring the power supply. Someone pulled the plug to do the vacuuming and forgot to put it back? etc etc.
