This is a digital learning combustible gas alarm (it is a combustible gas concentration according to customer requirements for automatic learning to save data, so that the concentration of combustible gas deviation is smaller) and 20KHz-45KHz ultrasonic rat repellent, mosquito repellent multi-functional products. The international advanced gas sensing technology is adopted, and the cost-effective microprocessor is selected as the control core (the storage device of i2c-bus is adopted, and the two-wire protocol is followed, due to its features such as convenient interface, small size and no loss of data power). The product is used to continuously detect the concentration of indoor gas leakage. When the concentration of leakage reaches the set value, the detector will send out a sound-light alarm. When the concentration of indoor gas is lower than the set value, the detector will automatically return to the normal working state.
The system also incorporates a 20KHz-45KHz ultrasonic scanning generator. It can drive away mice, mosquitoes and animals sensitive to this batch. Can be widely used in the family kitchen, office, warehouse and so on as the combustible gas leakage alarm and drive away the rat harm effective drive away sharps. Achieved the effect that a machine is multi-purpose truly, it is the good helper of house home, office, storehouse.
Wide operating voltage of the product. Can adapt to 100V to 240V power network. Digital tube is used to display the concentration of combustible gas leakage, with the function of warning and warning of low-concentration combustible gas, which can avoid the occurrence of poisoning, explosion, fire and other personal casualties and property loss accidents caused by combustible gas leakage. Reasonable structure design, PC anti - ultraviolet engineering plastic shell,safe and reliable!
