Product Specification

Working Mode

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 range set by the user, the transmitter will send data according to the set alarm interval (settable) to facilitate the customer to record the change of ambient temperature

Note: Priority: Temperature alarm mode > Low voltage alarm mode> Normal mode

Operating Instruction & Indicator status

7.1 On off operation and indicator status

Note: Please ensure that the power button is turned to ON when switching on and off the machine.
7.2 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 shutdown mode. 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 LED will 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:

Device indicator (Green + Red)| |
---|---|---
Device status| LED light| Priorita
Network exception| Red light flashes quickly (on for 0.1s and off for 0.1s)| 1
Power supply disconnect| Red light flashes slowly (on for 1 s and off for 1 s)| 2
Temperature alarm| Red light is on always| 3
Normal state| The green light flashes once when sending data| 4

Alarm Mode
The user can use the configuration software to set the temperature range to enable the temperature alarm function. When the temperature exceeds the limit, the machine is in the alarm mode. In the alarm mode, the machine will immediately send an alarm data, and subsequently collect and send data according to the collection interval and transmission frequency set by the user. After the temperature returns to normal, the alarm mode will be released and the previous acquisition interval will be restored.
At the same time, the machine has the local buzzer alarm function in the alarm mode. If the buzzer function is enabled (it is enabled by default and always beeps), the machine will beep according to the set buzzer time.
How to close the buzzer:

1. The temperature returns to normal;
2. Background sends 037 downlink command
3. The working time of the buzzer has expired;
4. Press the button;

Note: The buzzer will not work again until the temperature is abnormal again (the temperature returns to normal first and then abnormal)
Platform Data Query
Temperature & humidity monitoring platform:
Query website:http://t.tzonedigital.cn/
After power on, configure wifi and other parameters with configuration software, and users can query data on the Tzone platform. To access the platform, you need to register a user first, and then add the IMEI of WF501 in the “Device Management” of the “Basic Settings”. After adding the IMEI, you need to wait for a period of time for the user to query the data after the machine has reported the data.
Note: By default, the machine sends data to the server once every one minute of collection interval. The customer can also press the button, and the machine will immediately send data. The steps to query data are as follows:For more details, please click “help” button in the upper right corner of the platform![TZONE TZ-WF501 WiFi Temperature Sensor
