Description

technical field [0001] The invention relates to a rainwater alarm device, in particular to a rainwater alarm device controlled by a single-chip microcomputer, which belongs to the field of living appliances. Background technique [0002] The rain alarm device is a device that uses circuit control to alarm according to rain. When the control circuit detects that there is rainwater in the water holding device, the alarm device can be driven to give an audible and visual alarm. The equipment has its own power supply, and no human operation is required during use. The sound and light alarm is realized by a sound generator and a luminous tube, which is portable and reliable. The on-site installation and debugging of the equipment is simple, does not require professionals, is suitable for the general population, and is conducive to rapid and large-scale promotion. [0003] Most of the rainwater alarm devices in the current technology are controlled by electronic circuits. There ...
