¶ Main system
The main system fulfills the task of monitoring the weight of a beehive. Planned to hand over the system so that the data is transferred via nb-iot. The device is then switched to “Lorawan” via remote configuration. If there is a public gateway within range, this setting remains. If a transfer via lorawan fails, the system automatically switches back to transfer via nb-iot.
The main system consists of the following components:
hx711 pressure weight sensor electronic scale module 12v rs485 uart modbus rtu
The Lobaro Hybrid Modbus Gateway V2 with battery is suitable for Modbus ASCII / RTU readout. The uplink takes place via LoRaWAN or via NB-IoT. The product meets IP66 requirements and is suitable for outdoor use.

¶ Options
System expansions can be implemented modularly using a created connector system.
The plug-in module system is waterproof and suitable for outdoor use.
Here are the individual components:
¶ Y-connector
consisting of a plug, two sockets and a junction box
¶ extension cable
consists of a plug and a socket with variable cable lengths (here 2m)
¶ Temperature Humidity Sensor
RS485 Modbus Water Proof Temperature Humidity Sensor
¶ Sensor System modul
¶ Callibration Tool
Consisting of a USB to RS485/Modbus adapter, a 5 volt to 12 volt step-up module, and the connection socket that matches the scale module
With the calibration tool and the associated software, the accuracy of the scale can be easily increased. The scale is handed over calibrated and history has shown that the accuracy has not changed over many months. How this will behave over several years is difficult to predict.
