Greenhouse agricultural growth monitoring system for Internet of Things

The invention relates to a greenhouse agricultural growth monitoring system for the Internet of Things. The greenhouse agricultural growth monitoring system comprises a growth monitoring device, a program information sending device, a DSP processing chip and an audience rating counting device. The DSP processing chip, based on the program name of a current playing TV program, which is sent by the program information sending device, counts the times of the program name of the current playing TV program in a preset time period. The DSP processing chip, based on the counted times, updates in real time the playing frequency of the current playing program. The DSP processing chip also, based on the playing frequency of the current playing program, adjusts in real time the time duration of advertisements before future replay of the current playing TV program.
