pdf QK-G025 Application Note(latest version) Popular

QK-G025 module is an industrial grade product intended to provide remote control of DC motors or any DC powered devices. It allows operators to control remote equipment, machines by free call through GSM network. Up to four mobile phone numbers (SIM card numbers) can be registered with it. These mobile phones can belong to families/ technicians or engineers who have the requirements to control corresponding devices. Just dial from the registered SIM cards then the barriers or doors will be opened/closed, or the machine will be turned on/off. There are no call costs since this GSM control module will not answer the call and it will immediately take action after identifying the registered SIM card numbers.
