general description
This combination of LoRaWAN / NB-IoT transmitter and Truebner-RS485 sensors allow accurate measurement of soil moisture over long distances (LoRaWAN typical range in open air approx. 1km. NB-IoT mobile network)
The module comes completely preconfigured by us, and on request we can also adjust the cable lengths (standard length 10m, just shorten).
It includes 1x Dragino RS485 LoRaWAN / NB-IoT sensor, which can be used with up to 4x Truebner RS485 Modbus sensors can be connected. Select the sensors in our shop and we'll install them for you!
Possible here are SMT100, TH100 or Aquaflex, each in the RS485 Modbus version.
Read values
- In the variant 1-3x SMT100 the values soil moisture, temperature, permittivity and meter reading are read out
- In the 4xSMT100 variant, the values soil moisture, temperature and permittivity are read out
- The same applies to the Aquaflex option as to the SMT100
- With the TH100 option, the value for humidity and air temperature is read out
We configure the output as byte sequences, you will receive a corresponding description.
For the Chirpstack/ThingsIndustries/MQTT configuration, we also offer a customized decoder implementation (Javascript for Chirpstack Device Decoder).
Note: There are of course other combinations possible that we have not listed here, please inquire (see contact)
LoRaWAN Gateway
A corresponding recipient is required to collect the data. We distinguish between two categories:
a) Cloud-based data storage:
Here, the receiver (gateway) only serves as a forwarding instance, so the LoRa / LoRaWAN receives data and forwards it to a cloud service, e.g. ThingsIndustries
e.g. the Dragino MS20
b) Local server
With this variant, the data remains stored on the gateway and can be retrieved from there; MQTT is also directly available
e.g. the Dragino LPS8v2
NB-IoT
The mobile operator usually provides a platform
OpenSprinkler
For combination with OpenSprinkler All of the above variants are possible. Make sure MQTT is configured.
