Wireless Temperature & Humidity Sensor
Monitor any environment in real time — wirelessly transmitting temperature and humidity data to the cloud or a local server via IoT MQTT protocol, with full-colour LCD display and automated alerts.
Regtcom Engineering Company is the authorised distributor
OMEGA IoT solutions in Saudi Arabia and the GCC.
The OMEGA WT-TRH-S45 is a wireless IoT temperature and humidity sensor that transmits live T&H data to the cloud or a local server via MQTT protocol. Designed for a wide range of controlled environments — from pharmaceutical cold rooms to warehouse BMS systems — the WT-TRH-S45 provides high-precision monitoring with customisable dashboards, automated alerts, and 15-day on-board data memory.
Key Features
Wireless Wi-Fi Transmission
Data transmitted wirelessly over Wi-Fi 802.xx via local router — no cables required.
Cloud & On-Premise
MQTT protocol supports cloud-hosted or local server deployment — configurable per your IT requirements.
15-Day Data Memory
On-board memory stores 15 days of data — automatically transfers to server on reconnection.
Remote Configuration
Initial setup via Bluetooth mobile app; remote parameter setting and calibration via web browser.
High Precision
Temperature accuracy ±0.1°C and humidity accuracy ±1% for reliable controlled-environment monitoring.
Scalable Dashboards
World-class, customisable dashboards for live data monitoring, alerts, notifications, and reports.
Full Colour LCD
2.7" colour LCD showing temperature, humidity, date, time, and set-point range with audio/visual alerts.
Easy Maintenance
Touch buttons for on-device configuration. Simple probe maintenance and replacement design.

How It Works
Sense
The WT-TRH-S45 sensor probes continuously measure ambient temperature and relative humidity every 5 seconds or as configured.
Transmit
Data is wirelessly transmitted over Wi-Fi to your cloud server or local network using secure MQTT IoT protocol.
Monitor & Alert
Live data appears on scalable cloud dashboards. Audio/visual alerts and automated notifications trigger when thresholds are breached.
