Wireless pH Monitoring via NB-IoT and LoRaWAN
At Telemetry2U, we utilise wireless technologies like NB-IoT and LoRaWAN to connect your pH sensors to the cloud, offering robust solutions for diverse monitoring needs. NB-IoT, an extension of the LTE/5G network, provides exceptional coverage even in remote or underground locations, while maintaining ultra-low power consumption. LoRaWAN enables long-range communication across multiple sensors with minimal infrastructure. Combining both technologies, Telemetry2U delivers reliable, scalable, and real-time wireless pH monitoring in any environment.
ANB Sensor Integration Using MODBUS and Dragino Hardware
Integrating ANB pH sensors with the Telemetry2U cloud platform is simple. Using MODBUS communication and Dragino LoRaWAN/NB-IoT devices, you can quickly enable real-time data monitoring. The setup process is straightforward and supports remote access, alerting, and historical data logging.
Configure the ANB pH Sensor
Thanks to the standardised MODBUS RTU interface, integration is straightforward. Refer to ANB's documentation and use Dragino's RS485 devices, available in LoRaWAN and NB-IoT versions.
- Connect to ANB OC300: Default settings 57600, 8, N, 1.
- Controlled Sampling: Send MODE, select 1.
- Enable MODBUS: Use INTERFACE, select 2, default address 0x55.
- Wiring: Connect RS485 A- and B+ lines.
Configure the Dragino RS485 Converter
Set up the Dragino device to send MODBUS commands for sensor warm-up, reading, and shutdown. A 5-minute delay is recommended to ensure stability. Read Dragino's documentation for full instructions.
- Connect: Use PC or smartphone to connect to the Dragino device.
- Set Baud: Send AT+BAUD=57600.
- Command Set: Program the following command sequence to run at each interval.
Note: Set the Dragino transmit interval to 60 minutes (AT+TDC=3600000) to protect sensor life.
| Command | Data Cut | Delay | Function |
|---|---|---|---|
| AT+COMMAND1=55 06 00 00 00 03,1 | AT+DATACUT1=0,0,0 | AT+CMDDL1=60000 | Start fresh water scan |
| AT+COMMAND2=100,0 | AT+DATACUT2=0,0,0 | AT+CMDDL2=60000 | 1-minute delay |
| AT+COMMAND3=100,0 | AT+DATACUT3=0,0,0 | AT+CMDDL3=60000 | 1-minute delay |
| AT+COMMAND4=100,0 | AT+DATACUT4=0,0,0 | AT+CMDDL4=60000 | 1-minute delay |
| AT+COMMAND5=55 03 00 00 00 0B,1 | AT+DATACUT5=27,2,4~21 | AT+CMDDL5=400 | Read Registers |
| AT+COMMAND6=55 06 00 00 00 00,1 | AT+DATACUT6=0,0,0 | AT+CMDDL6=400 | Stop Scanning |
Command 1: Starts scan. Commands 2–4: Add 3-minute delay. Command 5: Reads data from bytes 4–21. Command 6: Stops scan.
Now just add the Dragino device to Telemetry2U, select the ANB pH Sensor V1.0 decoder and you'll be able to see the pH sensor data in real time – It’s as simple as that.
