About

Sensor sender

Features
Read full description

Turn your device into a sensor you can stream from. Sensor Sender reads your device's motion, position, and environment sensors and sends the values, live, to somewhere you choose. A laptop running a game engine, a synth, a microcontroller, or a visual on the same Wi-Fi. WHAT IT READS • Accelerometer, gyroscope, magnetometer, and combined device motion • Location, compass heading, and step count • Barometer, ambient light, microphone level, and battery • Touch and QR / barcode scanning WHERE IT SENDS • OSC, MQTT, HTTP/HTTPS, or UDP • Straight to your endpoint. No account, no cloud service in the middle • Per-sensor toggles and rate limiting, so you only send what you need SEE WHAT YOU'RE SENDING Every sensor has a live chart, so you can check if a reading looks right before you wire it into anything. GOOD FOR Prototyping, interactive installations, motion-controlled visuals and audio, and research data collection. Anywhere you'd otherwise build custom hardware to get the same numbers. Sensor Sender only sends. You bring the receiver: any OSC, MQTT, HTTP, or UDP endpoint you already have, or can run yourself.
