Project #15: Environment - Buzzer - Mk36

Project #29 - DFRobot - RTC - Mk31

Project #28 – Sensors – Touch Sensor – Mk15

eBUS Adapter Stick C6 is a reduced size version of previous highly demanded eBUS Adapter Shields and provides an interface to a 2-wire eBUS with galvanic isolation for enabling communication with an eBUS enabled heating, ventilation or solar system. With a size of 42 x 16 mm it is way smaller than the previous Shield versions, but still supports an USR-ES1 module being plugged onto it for having Ethernet access. Even better, with the upcoming firmware version for the ESP32-C6, it automatically scans the heating components and makes all data available via MQTT to e.g. Home Assistant with auto discovery of entities.

Project #30 - UNIHIKER - MEMS CH4 - Mk06

One of the best Chinese produced Energy Monitor ASICs now easier than ever to use

This is an old circuit built with analog components.

This device is better than the similar devices made with an Arduino microcontroller board thanks to the stronger microprocessor and the well-made Windows software.

A low-cost MEMS gyrocompass measures Earth s rotation to determine true north and latitude, independent of magnetic fields.

Project #28 – Sensors – MQ-135 Gas Sensor – Mk22

This project presents a compact system capable of determining the direction and elevation of a sound source in real-time with Pi PICO

Hackable, fully open-source gamma-ray spectrometer using a scintillator crystal and popular silicon photomultipliers.

This is a modern digital interpretation of a traditional barograph that displays real-time atmospheric pressure trends over a 24-hour period using a high-precision BME280 sensor and ESP32 microcontroller.

An environmental monitor board with AI support.
