Add-on Module

Atlas Sense

Camera, 9DOF, and 3× M5 Unit sensors — on any Atlas.

Atlas Sense attaches to the back or lid of Atlas SP, DS, and Tablet. One module adds an integrated camera, a 9-axis motion sensor, and three ports for M5 Stack Unit sensors so you can extend activities with environment, motion, distance, and more.

Designed for the same philosophy: one focus, gentle pace, and learning through the senses — with real-world data from light, temperature, motion, and proximity.

What is Atlas Sense?

Atlas Sense is an add-on module that mounts to the back or lid of Atlas SP (single-screen), DS (dual-screen), and Tablet (classic). It does not replace the device — it extends it.

Built-in capabilities:

  • ◇ Integrated camera — QR and card scanning, visual activities, and on-device processing only; no cloud upload.
  • ◇ 9DOF sensor — accelerometer, gyroscope, and magnetometer for orientation, tilt, and motion-aware activities.
  • ◇ 3× M5 Stack Unit ports — plug in up to three M5 Unit sensors (environment, motion, distance, light, etc.) and use them in Atlas activities.

M5 Stack Unit Sensors

Atlas Sense supports up to three M5 Stack Unit sensors at once. Units use the Grove-style HY2.0-4P connector and are compatible with UIFlow and Arduino. Below are commonly used Units that work with Atlas Sense.

Unit ENV (U001) Temperature, humidity, and atmospheric pressure. DHT12 + BMP280. I2C, PORT A.
Unit PIR (U004) Passive infrared motion detection. Human body sensing, ~500 cm range. Digital, PORT B.
Unit ToF Time-of-flight distance sensor. Range finding and proximity. I2C.
Unit Light Ambient light sensor. Brightness and daylight detection. Analog/I2C.
Unit ADC Analog-to-digital converter. Connect analog sensors (potentiometers, analog temp, etc.).
Unit RELAY Relay module. Switch external devices on/off from Atlas activities.
Unit Thermistor (NTC) Temperature sensing via thermistor. Good for ambient or surface temperature.
Unit RFID RFID 125 kHz read/write. Identify cards or tags for personalized activities.
Unit IR Infrared transmitter and receiver. Remote control or line-of-sight communication.
Unit Laser Laser time-of-flight distance. Precise range measurement.

Mix and match any three Units that use I2C or the supported digital/analog ports. New M5 Unit modules are released regularly; check M5Stack documentation for the latest list and pin compatibility.

Compatibility

Atlas Sense is designed to attach to:

  • ✓ Atlas SP (single-screen)
  • ✓ Atlas DS (dual-screen)
  • ✓ Atlas Tablet (classic)

Mounting is on the back or lid of the device so the main screen and controls stay unobstructed. Activities can use the camera, 9DOF data, and any connected M5 Units together — for example, a weather station with ENV, a motion-activated story with PIR, or a distance-based game with ToF.
