A wireless network based on AR4xx series devices enables remote measurement and recording of temperature, humidity and other physical quantities (pressure, level, speed, etc.) converted to a standard electrical signal (0/4÷20 mA, 0÷10 V, 0÷60 mV). Radio transmission takes place in the ISM 868 MHz band with FSK modulation. Range up to 700m in open space with the possibility of increasing up to 1400m when the retransmission function is activated in the sensors.
Measurements from the AR43x wireless sensors are transmitted by radio to the AR40x base station (AR407/AR408/AR406), which records the data in internal memory or USB memory stick. The AR40x allows the presentation of up to 16 measurement channels. Access to the AR40x base station is possible via the Ethernet, USB or RS485 interface. The AR40x also has a built-in web server so it is possible to view current measurements, status of alarm outputs, logging, internal time, etc. on the LAN and the Internet using any web browser (Opera, Edge, Firefox, etc.).
