Overview
What are Efento Bluetooth Low Energy loggers
Efento Bluetooth Low Energy (BLE) Loggers are wireless measurement devices designed to monitor environmental or process parameters (such as temperature, humidity, air pressure, VOC, open/close status, water leakage, or pulse counting) and transmit data over a Bluetooth Low Energy interface.
These loggers can be used in two basic modes:
Standalone mode — direct connection to a smartphone/tablet using the free mobile application, for local reading and configuration.
Connected mode — via Efento Gateway, which forwards logger data to Efento Cloud (or any other compatible cloud platform), enabling remote monitoring and centralized data collection.
They are battery‑powered and, depending on the usage settings, can operate maintenance‑free for up to 5 years.
Key features and capabilities
Multiple sensor channels — A single logger can support up to six measurement “slots,” allowing one device to monitor several parameters simultaneously (e.g., temperature + humidity + pressure).
Flexible measurement intervals — The interval between consecutive measurements can be configured by the user, from as frequent as 1 second up to once every 10 days.
Large local memory — Loggers store a large number of measurements internally (up to 40 000 records depending on model/configuration), allowing for long-term data logging even without frequent data extraction.
Bluetooth Low Energy communication — Enables wireless data retrieval or configuration using a smartphone (or via Efento Gateway), without cables or physical connections.
Battery‑powered with long autonomy — Designed for up to 5 years of battery life under typical settings, reducing maintenance needs.
Compact and easy to install — enclosures made from ABS, with small form factor and multiple mounting options.
Secure data transmission — Supports AES‑128 encryption and secure pairing to protect measurement data and prevent unauthorized access.
