Use case:  Remote Environmental Monitoring with Notification System

OBJECTIVE:

Monitor and receive real-time notifications for critical levels of ORP (Oxidation-Reduction Potential) or pH values and water level in a remote location using the EM-ORP/PH/AI signal transmitter and EM-COM GSM communicator.

COMPONENTS:

1. EM-ORP/PH/AI Signal Transmitter:
    - Capable of receiving signals from ORP or pH sensors or analog sensors with 4-20mA or 0-10V output.
    - Transmits data using the Modbus-RTU protocol.

2. EM-COM GSM Communicator:
    - Maps Modbus registers of connected devices.
    - Sends notification SMS to a predefined phone number based on set triggers.

SCENARIO:

1. Installation:

• Place the EM-ORP/PH/AI signal transmitter in the location where environmental monitoring is required. Connect it to the ORP or pH sensors and analog sensors as needed.
• Install the EM-COM GSM communicator in a location with GSM network coverage and connect it to the EM-ORP/PH/AI signal transmitter.

2. Configuration:

• Configure the EM-ORP/PH/AI signal transmitter to read data from the connected sensors, calibrate sensors.
• Set up the EM-COM GSM communicator to map the Modbus registers of the EM-ORP/PH/AI signal transmitter.

3. Trigger Setup:

• Define trigger levels for both ORP/pH and water level values in the EM-COM GSM communicator. For example, set a trigger to send an SMS notification if the ORP/pH value goes below a certain threshold or if the water level value indicates a critical condition.

4. Real-Time Monitoring:

• The EM-ORP/PH/AI signal transmitter continuously monitors the sensor outputs in real-time.
• When the predefined trigger levels are reached, the EM-COM GSM communicator detects the condition and initiates an SMS notification.

5. Notification:
• Users receive SMS notifications on their designated phone numbers, alerting them to the specific sensor readings that have exceeded the set thresholds.

BENEFITS:

• Enables remote monitoring of environmental conditions in real-time.
• Immediate notification of critical events, allowing for prompt intervention.
• Reduces the need for physical presence at the monitoring location.
• Enhances proactive management of environmental parameters.

APPLICATIONS:

• Water quality monitoring in remote or unmanned locations.
• Industrial processes where pH / ORP levels are critical for product quality.
• Other environmental remote measurements.

SUMMARY:

This use case illustrates how the combination of the EM-ORP/PH/AI signal transmitter and EM-COM GSM communicator provides an effective solution for remote environmental monitoring with timely notifications based on user-defined trigger levels.
