I reclaimed on the balcony of a vegetable plot. Suffer from the summer sun is too fierce, the balcony planted a dish to the noon Yan. So I am ready to take a stand when the temperature is above 32 degrees Celsius, by decelerating the stepping motor drive chain, expand shade net, when the temperature is below 27 degrees Celsius, to recover the shade net. Incidentally, the automatic watering also was filled.
Step 1: Preparation-First to visit my balcony cultivated vegetable.
Step 2:Prepare the eletronics accessories you need here-
Feature about this DHT11 Temperature Humidity Sensor Module for Arduino
1)Can detect surrounding environment of the humidity and temperature
2)DHT11 sensor adopts
3)Humidity measurement range: 20% 95% (0 degrees-50 degrees range) humidity measurement error: +-5%
4)Temperature measurement range: 0 degrees-50 degrees temperature measurement error: +-2 degrees
5)Working voltage 3.3 V-5 V
6)Output form digital output
7)It has fixed bolt hole and easy installation
8)PCB size: 3.2 cm * 1.4 cm
Any incomplete details will update later :)

Step 4: Design my plant shelf-
Step 5: Pross the watering system
Finally my plant gets water ^0^
The valve opens periodically, and closes after a specific interval. The period and the interval can be configured over Bluetooth. They are stored in the EEPROM memory of the PIC16F684,so they don’t erase when you disconnect the power.

Thanks for our partner RoboRemo’s detailed process about plant watering system and Hope the little projects will be useful for you about how to solve the DIY plant watering system.
