But the very tragic things happened in the last week. As the cold air from Siberia, Shenzhen has suffered low temperature and humidity for than 10 days. The temperature is about 10 degree, makes me fell chilling every day. The very bad thing happened: Jack and Jose, leaved me away……
It was such a sad afternoon. After I buried them, I had a new idea on my way home: I need to create a house, a house with floor heating, air conditioning, for my further new friends.
Step 1: Module Preparing
As a software engineer, I am not good at hardware, So i decided to use the most easy-to-use platform: Arduino
After browsing on the web, I got the following modules:
１. Crwoduino: an Arduino compatible platform, with some upgrading features to make it easy to use.
２. Temperature & Humidity Sensor and a 4.7K Resistor. I need this sensor to report the controller the current temperature and humidity.
３. LCD Keypad Shield. With this LCD I can monitor the current temperature and humidity, thus to make this project practical in my daily life.
４. 2-Channel Relay Module. As the Ultrasonic Nebulizer uses power more than 5V, so a relay module was used to control the Ultrasonic Nebulizer on/off.
５.A Ultrasonic Nebulizer to increase the air humidity.
６. Screw Shield , this shield helps me connecting the wires easier.
７. Thermal Tablet: this thermal tablet acts as heater for the pet house.
８. Some Wires or Wires would be needed
Basically, the temperature& humidity sensor reports to the Crowduino how cold it is now. If the Crowduino “think” it is too cold, then it will open the thermal tablet to warm the hamster or the ultrasonic nebulizer to begin the air humidification.
