Working Mode
|
Working mode
|
Working condition
|
|---|---|
|
Normal mode
|
The device collects the temperature data at the configured acquisition interval and then enables the module to send the data.
|
|
Low voltage alarm mode
|
When the device voltage is lower than 3.55V(configurable), it will no longer send data, but store the data and send it after the device returns to normal
|
|
Temperature alarm mode
|
When the ambient temperature exceeds the preset limit by user, the device can collect and send data at arelatively faster interval to facilitate users to recordthe changes of ambient temperature

To judge device current status by indicator
After startup, if you need to know the device current status, you can check the indicator status
as shown in the table below. If the indicator does not work, it indicates that the device is in shutdownmode. When the device sends data, the indicator will flash once, green light standing for normal
temperature and red light standing for abnormal temperature. The device LED will flash quickly when generating the PDF report, after finished, the LEDwill li
ght in green.The indicator status has priority. The larger the value is, the higher the priority is. The
indicator status is as follows:

Buzzer Working Mode
When temperature exceeds the limit, the buzzer rings with bee-bee sound. Situation or operation to stop the buzzer beep:
1. Temperature returns to normal;
2. Short press the button to turn off the buzzer. Note: The buzzer will not ring again until next abnormal temperature (the temperaturereturns to normal first and then abnormal).
Platform Data Query
Temperature & humidity monitoring platform:
Query website:http://t.tzonedigital.cn/
Domain name of TZONE server: t-gateway.tzonedigital.cn
TZONE server port: 54929
After startup, the device’s data can be queried on TZONE platform. When enteringthe platform, you need to register at first, and then add the IMEI number of WiFi501B into “Device Management” of “Basic Settings”. After adding, please wait for a moment because the device sends a real-time data to the server per 1 minute by default.
