ThermoSense Wireless Communicating Thermostats

System Architecture

ThermoSense wireless intelligent thermostat leverages advanced NRF technology, ensuring high speed and long-range signal propagation for real-time control and monitoring.

Our smart gateway collects near real-time data from all wireless sensors within range, converts it into an easy-to-use JSON format, and publishes it via the MQTT protocol.

Data can be transmitted to any local or cloud MQTT broker through Ethernet, LTE (4G), or WIFI.

Integration to Building Management System (BMS) can be achieved using MQTT broker or through an external BACnet converter.

ThermoSense wireless intelligent thermostats can be centrally controlled from MachineSens IoT Cloud Platform.

The MachineSens IoT Cloud Platform enables: –

  • Monitoring & Control: ThermoSensewireless intelligent thermostat enables remote monitoring and control of the AC equipment.
  • Data Analysis: IoT devices transmit this data to a cloud based central software system for real-time analysis and notifications.
  • Optimal Setpoints: The IoT solution (Hardware + Software) enables automated or centralized control of the Terminal unit’s temperature to maintain comfort while minimizing energy consumption.
  • Reporting: The system can generate energy usage reports (virtual metering), helping users understand their consumption patterns and make informed decisions.
  • Programmed Schedules:
    • Scheduling – Desire schedules can be programmed in the cloud-based software platform for control & monitoring. The IoT system can respond to demand response signals, reducing energy usage during peak periods. Specific times for system operation, such as when the HVAC should start or stop, temperature setting can be enabled or restricted.

The FCU and DX units set points and operation can be optimized
