Rolling sensor graph demo with Redis

Build a rolling sensor graph demo with Redis time series data

This guide family shows how to build a compact rolling sensor graph demo backed by Redis time series.

Overview

This use case simulates three sensors that continuously send readings to Redis. A small web dashboard then queries Redis to show:

• A rolling graph of raw readings for each sensor
• Bucket summaries drawn directly under the same time axis
• Bucketed minimum, maximum, and average values
• A short retention window where old samples visibly expire

This makes it a good fit for demonstrating how Redis time series support:

• High-ingest telemetry workloads
• Time-window queries
• Aggregation over fixed buckets
• Short retention periods that bound data size

Available implementations

• redis-py - Build a local Python demo with three rolling sensor graphs, aligned bucket summaries, and visible sample expiration
• Node.js - Build the same rolling sensor graph demo with node-redis and a local Node.js server
• Java - Build the same rolling sensor graph demo with Jedis and a local Java server
• Java (Lettuce) - Build the same rolling sensor graph demo with async and reactive Lettuce APIs
• Go - Build the same rolling sensor graph demo with go-redis and a local Go server
• Rust - Build the same rolling sensor graph demo with redis-rs and a local Axum server
• .NET - Build the same rolling sensor graph demo with StackExchange.Redis and a local ASP.NET Core server
• PHP - Build the same rolling sensor graph demo with Predis and PHP's built-in development server
• Ruby - Build the same rolling sensor graph demo with redis-rb and a local WEBrick server
