Battery Installation

A. Monitor

1. Remove the battery cover.
2. Insert 2 alkaline 1.5V AA batteries, make sure batteries are oriented properly.
3. Put the battery cover back into place

B. Sensor

1. Rotate the battery cover counterclockwise to the right until the “▲”symbol aligns with the “●” symbol which is close to “OPEN” (figure 1).
2. Remove the battery cover.
3. Insert 1 alkaline 1.5V AA battery, make sure battery is oriented properly.
4. Put the battery cover back into place, rotate the battery cover clockwise to the left until the “▲”symbol aligns with the “●” symbol which is close to “LOCK” (figure 2).

Pairing

Before the first use, it’s necessary to pair the product. The monitor and sensor will automatically pair when all batteries are installed.
Note: Please ensure distance between the monitor and the sensor is within 5 meters when installing batteries.
If you have purchased multiple sensors, follow the steps below to automatically pair the product.

1. Install batteries in the monitor first.
2. Install battery in the first sensor, then attach the number label “1” onto the housing of sensor.
3. Install battery in the second sensor, then attach the number label “2” onto the housing of sensor.
4. Follow above steps to install batteries and attach labels for all sensors one by one, make sure the monitor displays the same serial number as the sensor.
5. The monitor and sensor will automatically pair when all batteries are installed.

Note:

1. If the pairing order is incorrect, press and hold the No(>) button on the monitor for 10 seconds to restore factory default settings, and then re-pair.
2. In order to ensure the accuracy of data display and the reliability of the product, it is recommended not to add more than 6 sensors.

Moisture Measurement

1. Make sure the probes are clean before use.
2. Soften the soil to be measured, break up pieces if it is hardened. Remove grass, leaves, pebbles and other debris
3. Gently insert the probe vertically into the softened soil. Press the soil tightly around the probes so that the probes are in close contact with the soil.
4. Read the % moisture value in the display.

Note:

1. It is recommended that probe head should be inserted into the soil at least 10cm when make the measurement.
2. When the soil moisture environment is stable, in order to save the battery power consumption of the sensor, the sensor will not continuously transmit data to the monitor. If there is no change in soil moisture readings after watering, please wait up to 30 minutes and then read the data.
3. The soil moisture is measured according to the national standard (mass moisture content) to obtain data. For example, 20% moisture refers to 200g of water in 1000g of soil. Please note that different measurement methods may yield different data.

Low Moisture Alarm

When the soil moisture level drops below 10%, the percentage symbol and the flower pot icon on the screen will flash. This function helps to remind you to water the plants and maintain their health

Light Intensity Measurement

Appropriate light does well in plant’s growth (some plants need more light than others). This function helps you understand the level of light and determine if adequate illumination for photosynthesis is being provided to the plants. The sensor can measure the intensity of light automatically and send the data to the monitor and display on the screen. Here is the list:

Temperature Measurement

The sensor can measure the environment temperature of the plant automatically and send the data to the monitor and display on the screen. Press SET button to set the unit of temperature as ℃ or ℉.

Time Setting

Press and hold the SET button for 3 seconds to enter the time setting mode, follow the steps below to set the time:

1. Use the number switch buttons < or > to choose either 24-hour or 12-hour format, press SET button to confirm and switch to the hour setting.
2. Use the number switch buttons < or > to adjust the hours, press SET button to confirm and switch to the minute setting.
3. Use the number buttons < or > to adjust the minutes, press SET button to confirm and save the time.

Disconnection Reminder

If the sensor (transmitter) and monitor (receiver) are placed beyond the specified working range, the wireless signal on the display screen will blink continuously, indicating that the sensor and monitor have disconnected. After 48 hours, the sensor that is out of range will no longer be displayed on the screen. Please ensure that the sensor and monitor are within the working range to maintain a reliable connection

Important Notes:

1. Do not cover the light sensor.
2. Do not put the probes into water or other liquids.
3. Do not force the probes into hard soil or at hard objects, as this can easily damage the probes.
4. Please use good quality alkaline batteries.
5. Water may not penetrate the soil evenly, try measuring at different locations and depths to get an accurate reading.
6. Please keep the unit away from metal objects, refrigerators, iron doors, metal surface, etc.
7. Please keep the sensor at least 1 meter above the ground level, as close proximity to the ground can affect the wireless working range.
8. It is recommended to take out the probes from the soil and wipe them every 1-2 weeks to ensure the accuracy of data.
9. Please note that the actual operating distance of wireless products may vary due to different environmental conditions
