1.Project video (in video format)
2.Project Steps
3.Fixed temperature and humidity sensor, four digit digital tube, light intensity sensor and dot matrix screen.
4.Connect four digit digital tube to realize environmental data display.
5.Use smart code software for programming.
First, create a program entry. The example code is as follows:
Then, the temperature, humidity and light intensity values are obtained and displayed on the four-way digital tube with a time interval of 2 seconds. The example code is as follows:
Then, set the light intensity threshold. When the light intensity is greater than the set value, the dot matrix screen displays “C”, otherwise it displays “O”. The example code is as follows:
Finally, complete all the codes. The example code is as follows:
6.Interesting: record the average or maximum value of the detection value over a period of time.
