Abstract: A remote-controlled electric sprinkler comprises: a control circuit, a motor, a sprinkler head, and a sensor. The control circuit controls the motor for rotating the sprinkler head and making the sprinkler head sprinkle water in a rotated pattern. The sensor senses and adjusts the rotation angle of the sprinkler head, so as to control the water sprinkling range and direction. In addition, the control circuit can also adjust the water sprinkling distance and amount of water of water sprinkled out of the sprinkler head to meet the environmental requirements.

Abstract: A solar lamp includes a refraction light tube, a housing mounted on the refraction light tube, a light emitting member mounted on the housing to emit a light source outward through the refraction light tube, an optical sensing switch mounted on the housing and connected to the light emitting member, and a solar receiving board mounted on the housing. Thus, the solar lamp is portable and available for outdoor use, thereby facilitating a user carrying and operating the solar lamp. In addition, the solar lamp functions as a water sprayer, thereby enhancing the versatility of the solar lamp.
