Individual 60GHz mmWave sensor module for labs, redundancy builds, or creative automations outside the bedroom. Ships pre-flashed with the same still-energy presence engine—just wire to your ESP32 and go.

Pre-Flashed Firmware

Same 4-state presence engine as the flagship kit—no compiling required

UART + I2C Breakout

Interface with any microcontroller or SBC via standard protocols

Experimental Use Cases

Office chairs, nurseries, pet beds—anywhere stillness detection matters

Beyond The Bedroom

Creative applications for still-energy detection

The same mmWave technology that powers bed presence works anywhere you need to detect stationary humans (or pets). Here are ideas from our community.

Office Chair Occupancy

Detect when you're sitting at your desk—even when perfectly still. Trigger 'focus mode' scenes or mute smart speakers automatically.

Technical note:

Mount sensor aimed at chair seat from desk underside

Nursery Sleep Monitoring

Non-contact presence detection for cribs and bassinets. Privacy-first alternative to camera-based baby monitors.

Technical note:

Requires careful Z-score tuning for infant breathing rates

Pet Bed Automation

Know when your dog or cat is sleeping in their bed. Control nearby heating pads or track rest patterns for senior pets.

Technical note:

Works best with pets >5kg due to radar cross-section

Lab Equipment Monitoring

Non-invasive occupancy detection for fume hoods, lab benches, or equipment stations without installing contact sensors.

Technical note:

Stainless steel environments may require shielding adjustments

Meditation Cushion Tracker

Log meditation sessions based on stillness duration on your cushion. Export data to wellness apps via MQTT.

Technical note:

Absolute Clear Delay should be extended to 60s+

Redundancy Backup

Keep a spare sensor on hand for critical automation deployments. Swap if primary sensor fails without waiting for shipping.

Technical note:

Flash same entity IDs for drop-in replacement
