This guide will cover how to add a temperature/humidity sensor to Home Assistant using MQTT and Circuit Python. It is assumed that you already have a Home Assistant server up and running and that you have already installed the Mosquitto broker Add-on.
No soldering is required for this project, its plug-and-play thanks to the Metro ESP32-S2’s STEMMA QT port and the many QT-friendly sensors we’ve got. Simply plug in the sensor and run the code to make customizable projects with sensing and Home Assistant!
This guide shows you how to configure the SHTC3 Humidity and Temperature sensor for Home Assistant, though other sensors can be used with just a little modification. This particular sensor has a wide range of temperatures, excellent accuracy, has low power consumption and has a Stemma QT port for plug and play without soldering…
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
