1 Overview

The DF702 series detector is a smart trash detector that can detect the empty

state of the trash, whether it is on fire, whether it is dumped, and it can also

detect the battery level of this equipment. And we can provide corresponding

application platform and data interface (API) for customers to test or integrate.

4 Technical Parameters

Detector principle: ultrasonic @ 112kHz

Detection distance: 2000mm (vertical)

Blind area: 150mm

Height error: 3mm

Temperature error: 2°C

Angle error: 2°C (optional)

Battery: Built-in non-rechargeable lithium battery, 7000mAh @ 3.6V,

Lifespan: 4 hours to upload data, use 5 years

Operating temperature: -20 ~ +70°C

Storage temperature: -40 ~+85°C

Protection level: IP66

Data upload interval:

Sensor detection time: It is detected once every 10 minutes by default. When

the detected state (full) and the last state change, the data is uploaded. After

uploading the data, the device enters a sleep state, otherwise the data is not

uploaded. (This time can be modified through serial port or application platform

delivery.)

Fixed upload time: Upload data every four hours by default. (This time can be

modified through serial port or platform delivery.) This time will not detect the

time conflict.

5 LoRa version testing

5.1 Use the gateway and network server provided by our

company

5.1.1 Preparation for Testing

Step 1 Connect to the gateway's power supply and network cable according to

the gateway's instruction manual (the gateway has been configured in advance,

you do not need to configure it again);

Note: We will email you the gateway manual before shipping.

Step 2 Open the device and use a screwdriver to open the device as shown in

Figure 5.1 and Figure 5.2.

Step 3 Connect the device to the power supply and connect the battery to the

circuit board. (The default is not connected to the power supply. Please connect

the power supply before use.) The yellow marks are shown in Figure 5.3 and .

Note: After connecting the power supply, please use a screwdriver to fix the shell

of the device and tighten it to achieve a waterproof effect; then the sensor

function can be tested.

Cardboard items can be used for simulated height testing before actual

installation.

Testing process:

Step 1 Leave the device stationary or fixed

Step 2 Referring to Figure 5.4 or Figure 5.5, place the item above or below the

probe of the device and block the probe (white part) so that d>15cm and d<30cm.

This can be used to simulate the situation where the trash is full;

(Note: 1 Due to the blind area of the ultrasonic probe itself, accurate data should

be measured when the distance d>15cm.)

(Note: The sensor can detect the distance d from the device probe to the object.

This distance is also a sign that the trash can be empty or full. The sensor detects

the distance d from the device probe to the item is less than 30cm (30cm is the

default alarm threshold, this value can be When the serial port or the platform is

modified downwards), the trash bin is full, otherwise the display is not full.)

Method 1: Place the object over the probe

Figure 5.4

Method 2: Place the Object Under the Probe

√：Indicates that the location of the device and the object is not correct;

Step 3 Use the magnet to restart the device

To restart the device: The position of the opposite side of the white marked pin

is the magnetic switch position. The magnet can be restarted by placing the

magnet in the magnetic switch position for 3 s and then removing the magnet.As

shown in Figure 5.6.(Each time the device is restarted, the device will report the

data once.)

Note:

1 When the device is restarted, there is no free LED or sound outside the

casing to indicate that the restart is successful.

2 But when the restart is successful, you can see that a led on the main circuit

board will be on, and when the data is sent, the led will go out.

Figure 5.6

Step 4 Observe the data of the previous step 3 on the application platform

provided by our company. At this time, the trash should display full. (Note: We

will provide you with a platform test account after shipment.)

Step 5 Move the object and increase the distance d to make d>30. After 10

minutes (this time is the time from the previous data), the data can be observed

again. At this time, the trash can display is not full.

Repeat steps 4 and 5 to test empty/full status and different height values;
