Wireless ERS Sensor ELEKTRONIKSYSTEM I UMEÅ ERS2 — low-power wireless connectivity, model ERS2

The ERS2 Wireless ERS Sensor from ELEKTRONIKSYSTEM I UMEÅ is a low-power wireless device for remote monitoring and data transmission. The sensor supports measurement of temperature, humidity, light and motion and is designed for battery-powered installations where long operational lifetime and reliable wireless connectivity are required. ERS2 is suitable for integration with IoT systems and asset monitoring setups that use LoRa communication.

Advantages

ERS2 offers energy-efficient operation to extend battery life, multi-parameter sensing (temperature, humidity, light, motion) in a single compact unit, and wireless LoRa connectivity for long-range, low-power data transfer. The design supports deployment in remote or difficult-to-access locations and integration into existing monitoring networks.

Suitable for

• Environmental monitoring (temperature and humidity logging)
• Light level monitoring in buildings and storage areas
• Motion detection for activity or intrusion monitoring
• Asset and equipment condition tracking with LoRa-based networks

Key specifications

• Measured parameters: temperature, relative humidity, ambient light, motion
• Wireless technology: LoRa (long-range, low-power)
• Power: battery-operated, optimized for low power consumption
• Typical use: remote monitoring and IoT integration
• Form factor: compact sensor enclosure suitable for indoor and sheltered outdoor use

How to use

Install the ERS2 sensor in the desired location where temperature, humidity, light or motion should be monitored. Insert batteries according to the manufacturer’s instructions, configure the device on a LoRa network or gateway following the integration procedure, and place the sensor so that its light and motion detectors are not obstructed. Regularly check battery status and data reception on the connected monitoring platform.

Recommendations

Position the sensor away from direct heat sources and protected from heavy rain if used outdoors; calibrate or verify readings against a reference device after installation and plan periodic battery replacement based on reporting frequency and environmental conditions.
