Equipment selection, or help with the whole farm?
Send your country and a description of the equipment or problem. We can recommend a device, prepare a kit or plan the farm equipment and integration. Add technical details when available.

Field sensors rarely speak the exact cloud format a buyer wants. A gateway must poll, map and publish data predictably.
Measurements that matter
- Sensor value and unit
- Register or input status
- MQTT topic and payload
- Publish success and retry state
Suggested hardware configuration
- RS485 or IO acquisition module
- Edge IoT gateway
- MQTT topic and payload mapping
- Cloud endpoint test before shipment
Equipment in the system
Example equipment arrangement. Check compatibility and agree who handles software, PLC/SCADA programming and site installation.
Data destination
Customer platform or an agreed third-party service
Information needed before quotation
- Sensor list and protocol
- Register map
- Broker endpoint and authentication
- Payload example
Recommended next steps
- Review MQTT acquisition
- Compare MQTT and HTTP
- Prepare payload sample

FAQ
What does SunGene need before quoting Industrial Sensor Data to MQTT?
For a quotation, send these details: Sensor list and protocol; Register map; Broker endpoint and authentication; Payload example. We use them to select sensors, gateways, power and the data connection.
Does the sensor itself need to support MQTT?
A supported gateway can read an analog or serial sensor and publish to an MQTT broker. Confirm the field interface, broker requirements and payload mapping for the selected gateway.
What must we agree with the receiving platform?
Agree topic names, value names, units, timestamps, authentication and acknowledgement behavior. Test a reading from the field device through to the receiving application before connecting additional points.
What should I check before selecting equipment?
Record these site details: Sensor value and unit; Register or input status; MQTT topic and payload. Check the sensor output, receiving input, power supply and installation conditions together. Confirm any required approvals for the exact model and destination.
