DESCRIPTION AND OPERATION PRINCIPLE
SWITCHING DEVICE DESCRIPTION
ROSSMA IIOT-AMS 1-WIRE switching device is designed to poll digital DS18B20 temperature
sensor independently using 1-Wire bus and transmit the received data in LoRaWAN® or NBiOT
network.
The switching device can be used in industrial enterprises, infrastructure of housing and
communal facilities, in hard-to-reach places (wells, basements). The switching device provides
the possibility to install control and measuring devices in places with no power supply, operates
in difficult climatic and weather conditions.
.
The switching device is manufactured with a 3.6 V power supply.
The power cell of the ROSSMA IIOT-AMS 1-WIRE switching device is a built-in battery with a
capacity of 1200/6000/9000/14000/19000 mAh, designed for up to 10 years service life when
counting readings and transmitting data once a day.
DATA COLLECTION AND TRANSMISSION ALGORITHM
Data acquisition via 1-Wire bus is performed discretely according to the specified interval. The
package with the received data is transmitted in wireless network with a period of 1 minute (it
is not recommended to set the discreteness to less than 1 minute for long-term autonomous
operation mode of ). The read data is stored in the switching device memory.
The data transmission period can be configured from 1 minute. By default, the manufacturer
sets the data transmission frequency to 1 time/hour. The data is transmitted on the specified
timer, which is installed in the internal memory of the switching device.
The switching device is powered by a built-in 3.6V power supply. The capacity of the 13A/h
power supply is calculated for the service life according to the table (for example):
ROSSMA IIOT-AMS 1-WIRE switching device provides instrument
functionality from the built-in power supply, allowing to install sensors with
the switching device in hard-to-reach locations where no power supply is
available.
.
WARNING: The switching device is equipped with a built-in power cell - a
non-rechargeable lithium-thionyl chloride (LiSOCL2) battery.
Attempts to
charge the battery can cause fire!
