Rain Sensor - Relay & RS485 Output
The rain-snow sensor is one of the components of the weather monitoring system. It is a device specifically used to measure whether it rains or snows outdoors or in nature. The appearance of this rain and snow sensor is made of high-strength ABS waterproof material, and the protection level is IP67. It senses rain and snow through the spiral metal coil on the top, and has an auto-heating function to avoid surface icing caused by severe cold weather in winter. When in use, an external sound and light alarm can be connected to increase the alarm function.
