Relative humidity and temperature sensor FEEL

wall-mountLoRaWANwireless

Overview
FEEL is a 2‑in‑1 connected indoor sensor for temperature and humidity, designed for professional deployments requiring remote telemetry, stable IoT connectivity and long battery life. Measurements are accessible via a secure cloud platform and can be managed at scale.

Key usages

• Remote environmental monitoring for offices, housing and asset rooms.
• HVAC verification and indoor comfort control through temperature and humidity tracking.
• Mass deployment: easy installation and centralized management for large fleets of sensors.

Main features

• Combined temperature and relative humidity sensing with low drift.
• Measurement accuracy: Temperature ±0.2°C; Humidity ±2% RH.
• Multi‑band LoRaWAN transceiver (region configurable) and optional Sigfox on specific references (dual connectivity available).
• Historical data mode with grouped frames (datalog) and transmission redundancy (multiple sends) to reduce data loss.
• Optimized PCB antenna to balance connectivity reliability and power consumption.
• NFC configuration via Nexelec TOUCH app (25+ configurable parameters: regional frequency, reporting cadence, indicators, thresholds, etc.).
• End‑to‑end security with double AES128 encryption.
• Anti‑theft measures: lockable mounting base and tamper/tear detection alert.
• Front push‑button for on‑demand measurement and immediate data sharing.

Power & autonomy
Powered by replaceable lithium cells. Supplied with 1 SAFT LS14500 (2600 mAh); second battery slot available to double autonomy. Very low consumption; typical autonomy depends on configuration and can reach multiple years according to vendor profiles.

Set contents

• 1 FEEL sensor.
• 1 battery included (SAFT LS14500).
• 1 mounting base (lockable).
• 2 nylon screws and plugs.
