Data Logger

A data logger is an electronic instrument that automatically monitors and records environmental measurements — such as temperature, humidity, pressure, or CO2 levels — over time. Data loggers operate autonomously, capturing readings at pre-set intervals and storing them in internal memory or transmitting them to a cloud platform.

Modern IoT data loggers go beyond simple recording. They connect via WiFi, 4G LTE, or Bluetooth to cloud dashboards, enabling real-time monitoring, instant alerts, and automated compliance reporting from anywhere in the world.

Data loggers are the foundation of any environmental monitoring system. Without continuous, automated recording, organisations risk undetected temperature excursions that can spoil pharmaceuticals, compromise food safety, or invalidate laboratory results. Manual temperature checks are unreliable, prone to human error, and impossible to scale across multiple locations.
