SensMax SensGuard ENS210 Wireless Temperature and Humidity Sensor

The SensGuard ENS210 wireless temperature and humidity sensor is an ultra-compact battery-powered sensor for remote climate monitoring in warehouses, cold storage rooms, supermarkets, HVAC systems, server rooms, museums, archives and other controlled environments.

The sensor measures both temperature and relative humidity in one compact device. It monitors temperatures from -30°C to +55°C and relative humidity from 0% to 100% RH, helping facility managers track environmental conditions without manual checks.

Readings are measured every 5 minutes and sent wirelessly to a compatible SensGuard gateway, such as SensGuard TCP LR X2. The gateway forwards data to the SensGuard cloud monitoring platform, where users can view reports, monitor trends and receive alerts when temperature or humidity limits are exceeded.

SensGuard ENS210 sends temperature and humidity readings wirelessly to a SensGuard gateway and cloud monitoring portal.

How the ENS210 Sensor Works

The ENS210 sensor measures temperature and relative humidity using an integrated digital climate sensor element. The compact sensor body is installed directly in the area where climate conditions must be monitored.

Every 5 minutes, the sensor records temperature and humidity readings and sends them over an AES-128 encrypted 868 MHz radio channel to a compatible SensGuard gateway. The gateway then sends the data to the SensGuard cloud platform for reporting, alerts and historical analysis.

The device includes a network diagnostic button and status LED, so users can check whether the sensor is connected to the gateway and cloud system.

Temperature and Humidity Monitoring

ENS210 is suitable for locations where both temperature and humidity affect product quality, comfort, storage conditions or equipment reliability. It is useful when a compact wireless sensor is needed without an external probe.

Typical examples include warehouses, food storage rooms, pharmacies, cold chain areas, server rooms, HVAC zones, museums, archives, greenhouses and commercial buildings.

Installation

The sensor is designed for quick, non-destructive installation. It is mounted using high-bond industrial double-sided adhesive tape on smooth surfaces such as plastic, metal, glass or painted walls.

The sensor should be installed in the area where temperature and humidity must be measured, while staying within wireless range of the SensGuard gateway. Avoid placing the device where it can be affected by direct heat sources, direct sunlight, water flow, ventilation outlets or other local conditions that do not represent the monitored area.

The sensor is shipped powered off to protect the built-in battery during storage and transport. To start operation, press and release the JOIN button and register the sensor in the SensGuard cloud portal using the connection wizard.

ENS210 is used for temperature and humidity monitoring in storage, HVAC, server rooms, museums and other controlled environments.

Compatible Gateway and Cloud Monitoring

The ENS210 sensor requires a compatible SensGuard gateway for online monitoring. The gateway receives wireless readings from the sensor and forwards them to the SensGuard cloud platform.

• SensGuard TCP LR X2 wireless gateway and data collector for SensGuard monitoring sensors.

In the cloud platform, users can review temperature and humidity history, configure thresholds, receive alerts and export monitoring reports. This supports daily supervision, quality control and audit documentation.

Typical Applications

SensGuard ENS210 is suitable for wireless climate monitoring where both temperature and humidity data are required.

• Food supermarkets and grocery stores for monitoring storage areas, display cases and climate-sensitive goods.
• Warehouses and logistics for temperature and humidity verification in storage zones.
• Pharmacies and healthcare facilities for monitoring medicine storage conditions.
• Cold chain and refrigeration areas for climate tracking in controlled storage rooms.
• HVAC systems and building automation for climate monitoring in rooms, ducts and technical areas.
• Server rooms and data centers for temperature and humidity supervision around IT equipment.
• Museums, galleries and archives for protecting climate-sensitive exhibits and historical materials.
• Greenhouses and agriculture for monitoring growing conditions and humidity levels.

Business Benefits

Wireless temperature and humidity monitoring helps organizations reduce manual checks and detect climate changes before they cause product loss, equipment problems or damage to sensitive materials. The ENS210 sensor provides both values in one compact device, which keeps installation simple.

Cloud reporting and alerts help teams react faster, maintain climate history and support internal quality control. The wireless design also makes it easier to add monitoring points in existing facilities without running signal cables to each measurement point.

• monitor temperature and humidity in one compact wireless sensor;
• reduce manual climate checks;
• receive alerts when thresholds are exceeded;
• keep historical reports for quality control and audit needs;
• protect food, medicine, equipment, exhibits and stored goods;
• add new monitoring points without running sensor cables to the gateway.

Example in Action

A food warehouse installs SensGuard ENS210 sensors in several storage zones. The sensors monitor both temperature and humidity and send readings to the SensGuard gateway every 5 minutes.

When humidity rises above the configured threshold, the monitoring system alerts the responsible staff. The warehouse team can react the same day, check ventilation or storage conditions, and reduce the risk of product damage.
