Log and graph biosignals (HR/ECG/ACC/PPG/etc..) from Polar H10 & OH1 sensors

Features & Capabilities

Polar Sensor Logger is a powerful Chrome extension for logging and graphing raw biosignals such as heart rate (HR), ECG, accelerometer (ACC), and photoplethysmogram (PPG) data from Polar H10, OH1, and Verity Sense sensors using the Polar SDK. It allows users to save sensor data files locally, share via email or Google Drive, and forward data using MQTT.

Compatible with various Polar sensor models and firmware (H10, OH1, Verity Sense, H7, H9), the extension supports in-depth biosignal recording including HR, RR intervals, ECG at ~130 Hz, PPG, accelerometer, gyroscope, and magnetometer data. Designed with privacy in mind, the app does not collect user data and requires permissions solely for Bluetooth scanning and file access. Polar Sensor Logger is ideal for researchers, fitness enthusiasts, and developers needing detailed biosignal data management and exporting capabilities from Polar wearables.

Was working great several months ago. Now connects, shows battery at 100% and HR sits forever 'waiting'. I know the H10 is good because Runkeeper (on same phone) connects and records HR just fine.
