Problems solved by technology
The real-time monitoring of pH value in this method is poor, requires a lot of energy of agricultural production personnel, and the production efficiency is extremely low. Once the agricultural production personnel are negligent, it is easy to affect the normal growth of plants in agricultural greenhouses due to too high or too low pH value.

The invention provides a pH value monitoring and automatic adjusting system for an agriculture greenhouse. The system comprises a pH value sensor, a pH value signal processing unit, a wireless transmitting unit, a wireless receiving unit, a microprocessor, a relay, a pH value adjusting device and a PC. The pH value sensor, the pH value signal processing unit and the wireless transmitting unit are electrically connected in sequence. The wireless receiving unit, the microprocessor and the PC are electrically connected in sequence. PH value monitoring software is installed on the PC. The pH value sensor collects pH values in the agriculture greenhouse and outputs the pH values to the pH value signal processing unit. The pH value signal processing unit processes pH value signals, and the wireless transmitting unit transmits the pH value signals wirelessly. The wireless receiving unit receives the pH value signals, and the microprocessor processes the pH value signals and outputs the signals to the PC. Because the pH value monitoring software is installed on the PC, the PC monitors the pH values in the agriculture greenhouse in real time, the system is high in real-time property and efficiency, the pH value signals are transmitted wirelessly, and complex wiring does not need to be carried out.
Description
technical field [0001] The invention relates to the field of pH value monitoring of agricultural greenhouses, and more particularly relates to a pH value monitoring and automatic adjustment system of agricultural greenhouses. Background technique [0002] The pH value (pH) is an important parameter for plant growth in agricultural greenhouses. Taking mushroom cultivation as an example, mycelium can grow when the pH value of the mushroom culture medium is between 5-8.5, and the pH value is between 6.5-7.0 (neutral to acidic). ) grow best. But such acidity is also most suitable for many miscellaneous bacteria, especially mold. If the pH value is adjusted to 7.0-7.5 (neutral to alkaline), the growth of miscellaneous bacteria can be inhibited, and the mycelium of mushrooms can also grow normally. However, the pH value of the mushroom medium is not constant. With the continuous growth of mycelia, the medium will gradually acidify, and the pH value will decrease, which will affe...
