Professional Indoor Temperature & Humidity Monitoring with Instant Alerts
Protect your valuable assets with the Polygon Technologies Temperature & Humidity Data Logger & Alerts System - a professionally engineered cloud-based monitoring solution designed and manufactured in South Africa.
Whether you're monitoring a cold room, server room, pharmacy, laboratory, food storage facility or any temperature-sensitive environment, this intelligent monitoring system continuously records temperature and humidity, instantly alerts you to alarm conditions, and securely stores your historical data in the cloud.
The system is supplied complete with a pre-wired industrial Modbus RTU RS485 SHT20 Temperature & Humidity Sensor, allowing for true plug-and-play installation with minimal setup required.
Using 2.4GHz Wi-Fi, the system automatically uploads temperature and humidity readings to the cloud every 10 minutes, allowing you to monitor your site from anywhere using the mobile app for Android and iPhone.
Should your temperature or humidity exceed your configured alarm limits, the system immediately sends a push notification to all authorised users, allowing rapid response before product loss or equipment damage occurs.
Designed for uninterrupted operation, the logger also supports an external 12V backup battery, ensuring continuous monitoring during power failures.
Your monitoring data is securely stored in the cloud for three months, with CSV export functionality and automated monthly email reports for easy record keeping and compliance.
