S20D WiFi Remote Temperature & Humidity Monitor

• WiFi Remote Monitoring: Uploads environmental data through a WiFi network for remote viewing and management.
• 24/7 Automatic Monitoring: Continuously collects environmental data without permanent on-site supervision.
• Internal and External Sensors: Supports built-in environmental monitoring and external probes for wider temperature applications.
• Multi-Point Monitoring: Expandable sensor connections allow several locations to be monitored from one system depending on configuration.
• High Temperature Accuracy: Listed temperature measurement accuracy is ±0.2°C.
• Over-Limit Alarm: Provides warnings when monitored values exceed configured upper or lower limits.
• Power Failure Alert: Designed to provide warning information when monitored power conditions are interrupted.
• Offline Data Recovery: Continues collecting data during temporary network interruption and can upload stored records after reconnection.
• Cloud Data Management: Historical information can be reviewed remotely for environmental management and traceability.
• Multiple Access Platforms: Supports Pengyun IoT mobile, web and compatible messaging-based monitoring services.

• Install the main unit at a representative monitoring location with stable WiFi coverage.
• Connect the required external probes and extension cables before configuring the monitoring points.
• Place sensors away from direct sunlight, heaters and localized airflow unless those conditions are intentionally being monitored.
• Connect the device to the Pengyun IoT platform and complete WiFi network configuration before remote use.
• Set appropriate upper and lower temperature or humidity alarm limits for the monitored environment.
• Verify remote data transmission and alarm notifications after installation.
• Keep sensor surfaces clean and avoid covering ventilation openings.
• Inspect probe cables and connectors regularly for damage, moisture or loose connections.
• Keep the main unit and electrical connectors protected from direct water exposure.
• Check historical records periodically to identify abnormal temperature or humidity trends.

Q: Is the S20D a WiFi or 4G monitoring device?
A: The S20D is the WiFi version. A suitable WiFi network is required for normal remote cloud communication.

Q: Can temperature be checked remotely?
A: Yes. Environmental data can be uploaded to the Pengyun IoT platform for remote viewing through supported mobile and web interfaces.

Q: What is the temperature range of the internal sensor?
A: The listed internal sensor range is -20°C to +60°C.

Q: What is the temperature range of the external probe?
A: The listed external probe range is -40°C to +120°C.

Q: Can multiple monitoring points be connected?
A: Yes. The system supports expandable external sensor connections. The exact number and type of monitoring points should be confirmed according to the selected configuration.

Q: What happens if WiFi is temporarily disconnected?
A: The device can continue collecting data locally and upload stored records after the network connection is restored.

Q: Can the system provide high-temperature or low-temperature alarms?
A: Yes. Alarm thresholds can be configured to provide warnings when monitored conditions exceed the selected limits.

Q: Is the S20D suitable for livestock farms?
A: Yes. It is suitable for remote monitoring of pig houses, poultry houses, breeding rooms, veterinary storage areas and other farm environments requiring continuous temperature and humidity supervision.
