Humidity Sensitive Switch Relay Module
- With relay output, this module is used to detect the humidity and control related the device power directly.
- This product make use of HR202 humidity sensor.
- The comparator outputs drive relays directly. It connects to 220V AC or other devices.
- With leads, sensor interface can be installed with pin.
- It's easy to install with 4 0.3cm fixing bolt hole.
- When ambient humidity exceeds the setting threshold value the relay sucks and shuts, what's more, the common terminal connects to the start.
- If the ambient humidity below the setting threshold value, the situation will be counter.
- Common, normally open and normally closed the three ports are equivalent to a dual-control switch.
- When the relay coil is electrified, the common will connect to the normally open, otherwise, the common will connect to normally closed.
