The junction box is a device for sensor signal acquisition and conversion, which is capable of receiving 4-20mA current signals directly from the sensor and sending the signal to the Sensorhub using the 485 protocol. This junction box has a reliable signal conversion and transmission function, which can accurately pass the data collected by the sensor to the Sensorhub for further processing and analysis.

It can receive signals from different types of sensors, such as Smart PH Electrode Sensor, Pressure Transmitter Sensor, Liquid Level Sensor, etc., to achieve monitoring and control of different parameters. At the same time, the junction box supports the 485 communication protocol and can interact with other devices to facilitate the linkage and remote monitoring between devices.
