OUTDOOR RAIN FOG DETECTOR SWITCH GEAR |
摘要 |
An outdoor rain fog detector switch gear has a hollow housing with roof and wall; an assembly locating portion to assemble and locate the rain fog detector switch gear onto the object; a retaining space; a punch hole to connect the retaining space with ambient environment; a circuit board connected with a power supply line that protrudes out of the housing to connect electrically with the control circuit of the intended electrical device. The circuit board is also connected with a signal line to output a switching control signal or digital detection signal. A moisture probe senses and detects the moisture in ambient environment. The circuit board permits to turn on/off its automatic switching control function depending on the sensing state of the moisture probe. A protective film is covered externally onto the circuit board for waterproofing. The moisture probe is exposed outside of the protective film.
