WiOne is a series of wireless devices for measuring relative humidity and/or air temperature with the data logging function. WiOne data loggers are used to control humidity and temperature in production halls, warehouses, laboratories and museums. Terminal and elements block diagram of WiOne is presented below. The device is battery powered (AA 3.6 V battery) or optionally from an AC adapter (depending on the model). The switch (marked as 2 in the diagram) is used to start recording/data transmission, while the LED (marked as 4) is used to provide information about the current status of the device (see table).
Switch to activate registration / communication
Switch used to start data recording / transmission - ON position. In the OFF position of the switch, the device (despite appropriate configuration) does not record data and does not send data.
Radio 868MHz (range up to 300m)
The LED informs about:
Battery / Power Connector
3.6V AA battery socket or AC power connector (depends on model)
The exact size and location of the sensor depends on device version
Configuration and reading of data using the CODAP-UART-M8 or CODAP-UART-U
WiOne devices are equipped with a two-state LED that indicates the current status of the device. Additional information about the built-in LED is shown in the table below.
Red LED (L1)
ON when the device is ready
Blue LED (L1)
ON during radio transmission
WiOne device has a ON-OFF switch to start/stop data recording/data transmission. In the OFF position of the switch, the device (despite the appropriate configuration) does not record data and does not send data.
Switch in ON position
Data transmission/recording is ON
Switch in OFF position
Data transmission/recording is OFF
Be careful when connecting the device. Incorrect connection may damage the device and/or damage other devices that are connected to the device or system.
All connections must be made when the power is off!
