- Transmits readings every 79.5 seconds · LCDscreen display for current reading.
When paired with a Observer2.0/3.0 Wi-Fi Gateway:
- View leaf wetness reading on the Live Data page of the AWN app (requires the gateway and your phone is using the same Wi-Fi network)
- Up to 8 channels supported. Channel names can be edited on the app.
- Battery level information displayed on the AWN App
When paired with a Weather Station Console (WS-2000/WS-5000/Observer2.0/3.0):
- View leaf wetness data in real-time on the Display
- Up to 8 channels supported. Channel names can be edited on the console(for WS-2000/WS-5000 only).
When uploaded to Ambient Weather Server:
- View current moisture data & history records & graph on the website
- Receive email alerts from the server
- Remote monitoring with smart phone, laptop, or computer by visiting the website
3. Setup Guide
3.1 Installing battery
1. Remove the battery door on the back of the transmitter by removing of the screws, as shown in Figure 2:
Figure 2: Battery installation
2. Insert one 1.5V AA battery(be aware of polarity: flat side of the battery go to the spring side of the battery compartment).
The moisture reading will display on the LCD screen immediately and normally update every 79.5 seconds (the sensor transmission update period).
Note: If no reading on the screen, make sure the battery is inserted the correct way or a proper reset happens. Do not install the battery backwards. You can permanently damage the sensor.
4. Close the battery door by installing the screws.
4. Sensor Placement
This device can be mounted to a pole (compatible diameter range: 25.4~50.8mm ; not included) with the included hose clamp. (The pole and installation set sold separately.)
Then adjust the angle according to the leaf surface:
When tight the nut: hand turn the nut until no further turns to be turned, then use a wrench to turn 1/3 ~ 1/2 turn and no more.
5. Wi-Fi Configuration with gateway
To view the sensor data on your mobile application and receive email alerts on our ambient server, you need to pair this device with ourWeatherHub Wi-Fi Gateway or WS-2000/WS-5000 or other compatible Weather Stations (sold separately).
5.1 Pair with Gateway
If the WeatherHub has been in operation, and you have never had any WH51 sensor setup before, just power up the sensor and WeatherHub will pick the sensor data automatically.
Note: The gateway can support max 8 WH51 sensors. Each new sensor will be recognized as a new channel according to the Power-on sequence. You may attach a label of the channel on each sensor for distinction. The channel name can be edited both on the app and ambientweather.net(will not sync, and it should be edited on your device setup page on ambientweather.net separately).
If you want to use a new WH51 sensor to replace the old one(already configured on certain channel), please try the following:
- Open the Sensor ID page on the AWN app, and find your old sensor ID.
- Power off the old sensor and power on the new sensor.
- Click Re-register on the Sensor ID page.
Then the new sensor will be learned and the old sensor will be erased.
5.2 Wi-Fi Connection for the Gateway
For this part, please refer to the manual of the ObserverIP2.0/3.0 or WeatherHub Wi-Fi gateway.
6. View Online Data with AWN App
When the Wi-Fi configuration is done( to tell the gateway to be hooked to your WiFi network), your sensor data as well as the sensor battery voltage information will be displayed on AWN App at the live data page.
Note: It requires your phone and the gateway to be in the same network when viewing your sensor live data on the AWN app. Live data is referring to current data received by the gateway. Live data is not stored on AWN app. However data was always pushed and saved on https://ambientweather.net/cloud ( under your registered account, and data can always be accessed via your browser.)
Detailed operation instructions can be found on the WeatherHub or ObserverIP2.0/3.0 manual.
7. Set Email Alerts
Once your device is added successfully on the Ambient Weather server, you may set alerts for the sensor on the website to get email notifications.
