Arduino Based Temperature and Humidity Data Logger and Intelligent Parking Lot

The information of the other two teams in Phase II is listed below:

Arduino Based Temperature and Humidity Data Logger

Zhixiang LI

Nowadays existing simple thermometers and humidity meters can provide readings but it is not good enough. I developed a system (see Fig. 1 and 2), which not only can measure and display the current temperature and humidity but also save information (maximum, minimum and average readings) into an external storage (SD card). Moreover, it is an intelligent alarm system. When the environment is extremely changed, the system can automatically control a humidifier and an air-conditioner for the change in indoor environment. In addition, this alarm system also can remind users when it happens.

For improving the user experience, the system makes use of wireless data communication (WiFi and Bluetooth). Users can use their smartphones to connect to this system to get the current temperature and humidity and read the past information from the SD card. Furthermore, the system can transmit the current humidity and temperature readings to a website via WiFi in every four seconds. Finally, users can remotely control infrared-based devices at home through the website.

Intelligent Parking Lot

Fangqiu SU, Huiyang WEN and Shining LOU

Intelligent Parking Lot is composed of photo-resistors, LEDs, a 7-segment display and an Arduino microcontroller (see Fig. 1). A photo-resistor is used to detect whether a car is parked in a car park space or not. The signal detected by the photo-resistors is sent to the Arduino microcontroller. The microcontroller converts the analogue signals to digital signals and the total number of available car park spaces is counted. This information is sent to the corresponding LEDs and the 7-segment display. The overall design is low-cost and can be applied to different parking lots to help drivers to find available car park spaces easily.
