8 CONNECTING TO NODE & GATEWAY
Wireless sensor network are becoming vital in civil engineering and geotechnical field. Encardio-rite offers
an innovative wireless solution that allows real-time monitoring of geotechnical and structural sensors in
challenging construction projects, with reliable data transfer over long distances without any delay.
The digital sensors (with SDI-12 or Modbus (RS-485) output ) are interfaced with the long range, low power
wireless network through model EWN-01D
digital node
that allows sensors to send recorded data to the
model EWG-01
gateway
with over 99% reliability, eliminating the need for running lengthy cables. The
gateway then uploads all the collected sensor data to the central/cloud server.
The digital node consists of a radio-transceiver with an antenna, a microcontroller, sensor module that
reads the sensor; a wireless communication module that transmits the digital data to the gateway, and a
processor that controls the two modules. It is a highly reliable integrated system, which is capable of
collecting data from
digital sensors and reporting measurements through RF wireless communication
network to the gateway.
The node is housed in a rugged enclosure designed for use in harsh environments with wide temperature
tolerance with resistance to moisture and humidity.
A cloud-hosted data management and configuration software can be used to manage the network. The
configuration can be done with an easy to use smartphone application that comes free with the system.
The system can generate automatic reports and provide automated alerts over SMS or email for any
reading crossing the pre-defined alert levels.
8.1 Sensors with SDI-12 output option
The sensor with SDI-12 output will be connected to the “SDI” port (right-most) of the digital node as shown
in figure below.
