SensorSentry

SensorSentry is a web app (with optional mobile alerts) for monitoring industrial and building sensors and flagging “silent failures” like drift, bias, stuck values, and intermittent dropouts. Instead of just charting time-series data, it continuously runs simple statistical health checks and cross-sensor sanity rules (e.g., supply/return temperature deltas, humidity/temperature plausibility, redundant sensor agreement). It connects to common sources like MQTT brokers, Modbus gateways, and CSV exports, then produces a clear health score per sensor, an audit trail of anomalies, and recommended actions (recalibrate, replace, check wiring, check placement). This is not magic: it won’t diagnose every root cause, but it will reliably reduce the time wasted chasing bad data and prevent control loops from being tuned around faulty readings. Pricing is per site or per sensor tier, aimed at teams who already have data but lack dependable sensor QA.
