SensGuard ENS210
Wireless Temperature and Humidity Sensor
Description
The SensGuard ENS210 is an industrial-grade, ultra-compact wireless sensor designed for simultaneous remote temperature and relative humidity monitoring in environments from -30°C to +55°C and 0% to 100% RH.
Featuring a fully integrated high-precision digital sensor element, this model provides excellent measurement accuracy and stability. The device is powered by an integrated 3.7V lithium battery that offers up to 5 years of autonomous operation. The battery is sealed inside the enclosure and is non-replaceable; once the operational lifetime has ended, the entire sensor unit must be replaced and recycled.
Data collected by the sensor is securely transmitted over an encrypted wireless radio link to a compatible SensGuard gateway for real-time tracking and cloud integration.
Key Features
- Combined Monitoring: Measures both temperature and relative humidity in a single, compact device.
- Long Battery Life: Up to 5 years of autonomous operation.
- Hermetic Design: Rated IP68 for excellent water and dust resistance.
- Secure Transmission: Fully encrypted radio link using AES-128 standard.
- On-Board Diagnostics: Dedicated network diagnostic button and status LED.
Typical Applications
- Commercial Refrigeration: Climate logging in supermarkets, food display cases, and cold storage rooms.
- Cold Chain & Warehousing: Temperature and humidity verification in pharmaceutical and grocery warehouses.
- HVAC & Building Automation: Climate monitoring in ventilation ducts and indoor living spaces.
- Server Rooms & Data Centers: Thermal and relative humidity tracking for high-density electronic racks.
- Museums & Archives: Preserving climate-sensitive historical artifacts and exhibition spaces.
Operating Instructions
Powering the Sensor On/Off
To prevent battery drain during transit and storage, the sensor is shipped in a powered-off state.
- Power On: Press and release the JOIN button.
- Power Off: Press and hold the JOIN button for 10 seconds.
Device Registration & Configuration
Measurement collection requires a compatible SensGuard gateway (e.g., SensGuard TCP LR X2). Follow these steps to register the sensor:
- Power on the sensor by pressing and releasing the JOIN button.
- Log into the SensGuard cloud portal at my.sensguard.lv and navigate to the Connection section.
- Launch the Connection Wizard and follow the step-by-step setup instructions.
- Once registered, the sensor becomes fully operational within five minutes (the sync time required for the gateway to apply the new hardware configuration).
Network Connection Diagnostics
You can verify the connection status at any time by pressing and releasing the JOIN button on the sensor body. The onboard STATUS LED indicator will display the current network state:
| LED Pattern | Network Status |
|---|---|
| Two short flashes | No connection to the gateway, or the sensor has not been registered in the system. |
| One long flash | Successful connection to the gateway and the SensGuard cloud system. |
