The DF702 sensor is designed for waste bin (trash bin) status detection, especially for trash/garbage bin full/empty detection. It detect full/empty, flame risk, inclined (fall) or not and etc. With LoRaWAN® module, it transmit the status via gateway to networks server and application server. User can monitor the status remotely. With the application software, user can assign the collector resource work plan and route plan. Analyze task performance and find out solution to improve. Finally the objective of high efficiency , good environment, and low cost are achieved. Furthermore it is optional with NB-IoT wireless module. It is also optional for different frequency, such as 470Mhz (China), 868Mhz (Europe), 915Mhz(USA), 923Mhz (Australia,New Zealand). As it is with algorithm of low power consumption, the internal battery can work for more than 5 years (at 4 hours interval upload interval). And the IP68 level ensure the endurable working outdoor.
Cautions: For safety, the battery in standard version of this device is non- recharged type. If out of power, please do not recharge it, please replace with new battery from our company. What's more, the battery can not work for more than +85℃.
To realize the user needs, we developed GPRS version in 2018
With GPRS module, it transmit the status via cell phone network to networks server and application server. User can monitor the status remotely.With the application software, user can assign the collector resource work plan and route plan. Finally the objective of high efficiency and low cost are achieved. It works for quad band frequency, 800/900/1800/1900Mhz. So it works worldwide. As it is with algorithm of low power consumption, the internal battery can work for more than 1 years (per day two times uploading). Comparing with the NB-IoT and LoRa versions，below is the different specification.

3.2 Monitoring Software
4 Protocol & Test
4.1 Communication Setting
For the RS232 communication, Baudrate 9600 or 115200, data bit 8, stop bit 1, no odd/even checksum.
4.2 Packet Format
Header 1 byte，$ in ascii and in hex 0x24 for the request to sensor. And * in ascii and in hex 0x2A for the reply from sensor. Tail 2 byte, in hex 0x0D 0A.
Refer to command list at Part 3. For command in reply is same as the command in request. ID 001~FFF Content 0~32 bytes. Checksum Sum of bytes from header to id, then select the low 8 bit, finally convert to ASCII and show in Hex. E.g. If sum is 0x0356, then low 8 bit is 0x56, to ascii, the value is 56(0x35 0x36 in Hex).
4.3 Command List
Generally the sensor automatically report the full status if it detect full level. If the server want to know the current status, it can send out request to ask for sensor to reply. The sensor will reply in the reply window. (maybe not instantly) Request for sensor 01 $RF0014D Reply from sensor *RF00117D 1 is the status, It is full level. 0 is not full.
