Introducing SENSE

SENSE is a tiny multipurpose sensor board for makers and educators. By integrating three sensors, a real-time clock, and a micro SD card holder, SENSE gives you the ability to monitor and take control of your environment.

My name is Zack Seifert and I am a seventeen-year-old electronics enthusiast and I designed SENSE to be a universal sensor board that can be used in any electronics project. I believe that SENSE would be a great addition to every maker’s toolkit to provide environmental data for any application.

Poor air quality?

Air conditioner/heater not working?

Classroom too loud?

Room too dark?

Door left open?

Incoming bad weather?

Like Specs? Here are some:

BME688 (I2C)

Measure temperature with ±1.0 °C accuracy, humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and altitude with ±1 meter accuracy. Can output IAQ, VOC, and equivalent CO2 with Bosch library.

APDS9960 (I2C)

Return how close object is to sensor, amount of red, blue, green, and clear light, and detect simple gestures (left to right, right to left, up to down, down to up).


Microphone pulse density modulation output. Can output decibels using example.

PCF8523 (I2C)

Provides year, month, day, weekday, hours, minutes, seconds and 100th seconds based on a 32.768 kHz quartz crystal.


Log data onto a micro SD card.


Easy use of I2C sensors.

Code Libraries

SENSE has support for the Arduino IDE, Circuit Python, and Python.


SENSE can be used for environmental sensing, home automation, or any other way you can think of. The applications are endless!

IoT Weather Station

Use sensors to collect weather data and then log it onto micro SD card or display it on the cloud. Take part in citizen science by uploading your data to openSenseMap.org

Smart Faucet

Use proximity or gesture sensing to automate your home. 

Clap Activated Switch

Use the microphone to turn a clap into a switch.
