| OWU-101S [Battery type] |
| OWU-102S [External power supply type] |
Features
By connecting devices such as existing sensor devices and switches, it can be used immediately as an IoT compatible device.
It is possible to launch an IoT business or service smoothly.
You can easily convert existing sensors and switches to IoT
By simply connecting the "IoT Wireless Unit" to existing sensors and switches, it is possible to easily realize the machines and systems currently being used IoT.
2-channel input compatible with contact signals and pulse signals
You can easily transfer contact signals and pulse signals from devices such as level sensors and temperature sensors, such as existing sensors and switches, to the cloud server via Sigfox.
Two models of battery drive and external power supply drive
The battery drive model has a long life of up to about 5 years * in alarm mode and up to about 10 years ** in pulse mode. Also, an external power supply type is available.
(*Transmission 10 times a day. **Transmission interval 12 hours.)
Outdoor waterproofing structure (IPX5)
It is a high waterproof structure to support IoT solutions in various fields. You can use it safely outside.
System configuration
By connecting an existing sensor with the dry contact converter, it is possible to link to a cloud server.
