ELSYS ERS Interact Lite Flex LoRa Temperature/Humidity Configurable Touch Sensor

The ELSYS ERS Series ERSILITE-F-L is an indoor temperature and humidity sensor designed for wall-mounted monitoring and remote data collection. It provides clear, at-a-glance readings on a 2.13-inch ePaper display and offers configurable touch buttons for local interaction. The sensor uses battery power with a lithium thionyl chloride AA form factor for low-power operation and supports adjustable sampling and data upload intervals to match monitoring needs. Built for wide-area IoT deployments, it communicates over LoRaWAN with NFC for easy provisioning and includes AES-based encryption and compliance with common regional standards. The device operates in typical indoor conditions and supports multiple regional frequency bands, making it suitable for building monitoring, climate control, and asset environments where long battery life and secure wireless reporting are important.
