The module is powered by V+ and GND screw terminals, the RS-485 line is connected to inputs A and B. the DS18B20 External temperature sensor is connected via a parasitic power supply circuit, when the +5V and GND terminals are connected and connected to the GND terminal, the data output is connected to the 1-W terminal. | |||
D | D some models have an internal temperature sensor DS18B20 in the case TO-92, soldered in the upper left part of the module Board (the top view of the sensor housing is printed in this place by silkscreen). | ||
