Description

Out of production. Manufacturing under the order is possible.

The module can be operated remotely with RS485 line (up to more than 1 km long) via standard Modbus RTU commands (read/write registers)

Size: 50x78x31 mm.

Inbuilt sensors: AM2320 (AOSONG) - temperature, humidity; BMP180 (BOSCH) - temperature, pressure.

Step: temperature - 0.1 °, humidity - 0.1%, pressure - 10 Pa.

Accuracy warning!  As far as temperature sensors are partly influenced by inside of the enclosure, there may be a few degrees shift in the measured temperature values so we recommend to calibrate temperature by using another (open) thermometer and subtracting the factual shift on the Modbus master side.

Power supply/power consumption: voltage - 5V, current - 30 mA.

Memory: non-volatile memory chip for settings.

Connection: screw connectors.

Modbus address: (can be changed by Modbus command) 0...255 (default address: 0x01).

Baudrate: (can be changed by Modbus command) 2400, 4800, 9600, 19200, 28800, 38400, 56000, 57600, 115200, 128000, 256000 (default is 9600).
