Jiangsu Du'an Environmental ProtectionNS-4 Integrated Submersible Pump Monitoring ControllerCraftsmanship excellenceThe communication management chip, which is connected to the microcontroller, communicates with the computer terminal and transmits the transformer's temperature information to the computer terminal. Preferably, a buzzer is also connected to the microcontroller, which is in turn connected to the circuit with the temperature probe. When the temperature probe makes poor contact, the buzzer emits an alarm. Preferably, the display unit includes a digital tube, a digital tube driver circuit unit, and a key input control unit, as well as a key signal input editing unit. The digital tube is connected to the digital tube driver circuit unit and the key input control unit. The key signal input editing unit is connected to the digital tube driver circuit unit and the key input control unit, which are also connected to the microcontroller.
