SensMax L3 Pro Customer Feedback System

The SensMax L3 Customer Feedback System is a wireless, self-contained solution designed for real-time customer satisfaction monitoring and automatic calculation of Net Promoter Score (NPS). Completely cable-free and simple to deploy in a variety of facilities, this 3-button survey device instantly captures visitor sentiment in retail stores, bank branches, airport terminals, public institutions and medical clinics.

Customers record their experience with a single tap on an intuitive emoji icon (Positive, Neutral, or Negative). Votes are instantly recorded in local internal storage and automatically transmitted to a central database, allowing for detailed satisfaction analysis over flexible time intervals—anytime, daily, weekly, monthly, or annually.

How the System Works

The unit operates completely autonomously, combining a battery-powered 3-button emoji layout with a dedicated plastic display stand for custom printed survey questions. Recorded votes are securely stored in local internal memory before being collected via radio frequency (RF) transmission by a central gateway. The gateway then sends telemetry to a central database via LAN or cellular (GSM) networks for ongoing reporting and analysis in the cloud.

Key Features & Technical Performance

• Extended Battery Autonomy: Low-power design operates on standard batteries, providing an operational lifespan of up to 2 years.

• On-Board Data Security: Internal memory autonomously stores up to 25 days of offline statistics, guarding against network disruptions.

• Automated Data Uploads: Gateways automatically retrieve recorded votes via RF radio and push data to central servers using LAN or cellular connections.

• SensMax EasyReport Analytics: Processed within the SensMax EasyReport application to generate intuitive graphic charts, tabular trend logs, and automated NPS calculations.

• SMART Analytics Integration: Seamlessly correlates foot traffic data from SensMax people counters with feedback metrics to calculate precise conversion rates and visitor-to-satisfaction ratios.
