The SENSE is a little board containing a number of sensors that collect data from the surroundings. To facilitate data logging, the gadget has a battery-powered RTC (Real Time Clock) and an SD card connection. Zack Seifert, a seventeen-year-old electronics enthusiast and president of his high school's robotics team, designed the gadget.
The BME688 (air quality, pressure, humidity, and temperature), the APDS9960 (proximity, light, RGB color sensing, and basic gesture sensing), and the SPK0641HT4H are all used in the SENSE board's sensing capabilities (PDI mic).
The SENSE board connects to microcontrollers through I2C, but Seifert also has documentation for Arduinos and Raspberry Pis, including CircuitPython. The SENSE's GitHub account may be accessed here.
Because the multi-sensor board is linked to an ESP32 microcontroller through Qwiic Connect in the sample below, it seems to be powered at 3.3V.
SENSE Board Specifications:
- Sensors:
- BME688 from Bosch which is an air quality sensor that detects gas, humidity, pressure, and temperature

- SPK0641HT4H from Knowles which is a low power PDM mic (Pulse Density Modulation)
- Storage:
- MicroSD card socket
- I/O Interface:
- 2x Qwiic connector
- 2x 7 pin header
- Other Features:
- PCF8523 from NXP (RTC)
- Power:

- Dimensions:
- Unspecified
SENSE Board Additional Information
The SENSE board was just launched on Kickstarter, and it has already surpassed its $1000 goal. With the early bird pricing, a single SENSE board costs $29, or two for $56 (plus $9 for delivery in the US). On the Sense board, you can buy pre-soldered header pins for an additional $3. The expected delivery date is September 2022.
