Featuring a coin-sized, rugged design, this smart temperature data logger captures measurements from −40 to 185°F (-40 to 85°C) in confined spaces. It includes a simple USB interface for fast data download and logger configuration using ACR software. Moreover, it stores over 2000 readings for extended use. Ideal for process validation, equipment and system monitoring, and long-term research, delivering data where larger instruments cannot fit.

Features
Designed for simple, reliable deployments
The SmartButton is built for applications where temperature data must be collected reliably without adding complexity to the system being monitored. Its ultra-compact, self-contained design allows it to be placed directly at the point of interest—inside packaging, equipment, storage areas, or transport containers—without interfering with normal operation. All sensing, data storage, power, and timing functions are integrated into a single sealed device, eliminating the need for external probes, wiring, or enclosures.
Straightforward configuration and operation
Once configured, the SmartButton operates autonomously. It records temperature according to the selected sampling interval and continues logging until the session is complete or the memory is full. Because there are no external connections to manage, deployment is quick and repeatable, making the SmartButton well-suited for both one-off studies and routine monitoring programs.
Clear data retrieval and reporting
Recorded data is downloaded using ACR’s TrendReader for SmartButton software, which is designed to make interpretation fast and intuitive. Temperature profiles can be reviewed immediately, with high and low zones clearly highlighted to identify excursions. Users can view minimum, maximum, and average values, compare multiple loggers or sessions, and export data for documentation or further analysis. This makes the SmartButton practical for validation work, audits, and troubleshooting, where clear records matter more than real-time dashboards.
Scales easily across multiple points
The SmartButton’s small size and cost profile make it practical to deploy many loggers simultaneously. This enables multi-point monitoring across rooms, storage locations, equipment, or shipments without the overhead of centralized systems or continuous connectivity. This approach is especially valuable in applications where understanding variation across locations is more important than streaming live data from a single point.
Suitable for a wide range of applications
SmartButton data loggers are commonly used in food production and storage, pharmaceutical and vaccine cold chains, equipment monitoring, validation studies, and general environmental tracking. Their simplicity, durability, and long service life make them well suited to both field and laboratory environments.
Accessories for flexible installation
A range of accessories is available to support different mounting and handling requirements, allowing the SmartButton to be adapted to specific deployment conditions. These accessories help ensure consistent placement, secure attachment, and repeatable results across applications.
TrendReader for SmartButton Software
TrendReader for SmartButton software is the companion application used to download, view, and analyze temperature data recorded by ACR SmartButton data loggers. The software is freely available for download from the ACR website and does not require any license, activation, or subscription. To communicate with a SmartButton and retrieve data, a compatible USB interface cable is required.
Key capabilities
Software access and installation
TrendReader for SmartButton software is available at no cost from the ACR downloads page
For convenience, SmartButton Starter Packs include a USB flash drive containing the software. However, downloading the latest version directly from the ACR website is typically preferred and ensures access to current releases.
