Project #30 - UNIHIKER - MEMS CH4 - Mk06

An environmental monitor board with AI support.

With a current consumption of only a few microamperes, this thermometer can operate for years on a single CR2032 battery—or indefinitely with a solar cell.

A project for automation, hobby and also learning.

Let’s take a look at this interesting All-in-one Starter Kit for Pico 2—a kit designed for learning electronics and programming, ideal for beginners and beyond. It allows users to begin their journey with the Pico 2 RP2350 processor in a simple and fun way. The kit comes in a small suitcase measuring 195 × 170 × 46 mm. Inside, there’s a single board equipped with as many as 17 sensors or modules serving various functions. It also features a 2.4″ full-color TFT touchscreen.

Electricity meter with touchscreen and remote access.

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.

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.
