NRI Electronics (NRIE) have developed long range, cost effective Wi-Fi base telemetry for remote monitoring and control. Wi-Fi is the preferred choice for connecting the Internet of Things ( IoT).  The Wi-Fi telemetry units not only support sensors but can be used for very cost effective site surveillance using low cost cameras.

Wi-Fi provides exceptional flexibility for monitoring now and into the future.  .

For those especially interested in soil moisture monitoring collected over the Wi-Fi please view real time data here

The NRIE Wi-Fi network consist of two or three parts.

1. Wi-Fi field station has inputs ( SDI-12 ) for sensors for monitoring soil moisture , weather and water sensors. Up to six SDI-12 devices can be attached to each field unit. Each station has four digital outputs for operating two latching solenoids. The integrated solar panel charges a small internal lithium battery. Field units can be supplied with high gain omni directional or yagi antennas up to 20 dB gain for very long distance tranmission. We are testing long range , high gain anttenas as of April, 2018.

2. Wi-Fi Access Point AP. The Wi-Fi access point is located on a building or mast and communicates with the remote field units. The Wi-Fi AP connects to any existing router. This means the customer does not need to purchase expensive Base stations and dedicated routers.

3 Wi-Fi Field terminal

The Field terminal is a an intermediate Wi-Fi terminal typically used to monitor are control diesel pump for irrigation.

Brief description.

The Wi-Fi field stations  are instructed to undertake data collection tasks from attached sensors.

The field stations can be configured from anywherein the world with internet connection. You do not need to know how to configure the units. If you wish to add another sensor later or replace a sensor then just connect it to the field unit and we can remotely configure it for you. If you wish to configure the field stations yourself then it is as easy as filling out a simple on line form and sending to the AP over the Internet.

Data can be handled in two ways.

1. Data is sent to our servers and converted to chart format. We have decades of experience charting data.

2. Data is processed on Raspberry Pi mini PC running mySCADA software under Linux at customer's office. This PC collects data from the AP and can forward to our cloud servers if required. The mini PC can be password accessed from anywhere in the world  We are currently developing control systems for irrigation control based on mySCADA software providing both local and Internet access..
