sensor
The Metriful MS430 is a low power, high accuracy smart sensor cluster for indoor environment monitoring. It operates via an I2C-compatible interface and measures eighteen variables including air quality, light, and sound levels. This repository provides documentation and software examples for using the MS430 with Raspberry Pi (0/2/3/4/Pico), Arduino, ESP8266, and ESP32 host systems. Code examples include interfaces to IFTTT, Home Assistant, ESPHome, IoT cloud platforms, real-time graph software, web servers, and interrupt detection. The repository includes a quick-start guide, a detailed User Guide explaining device measurements, and a Datasheet covering electrical and communications specifications. Hardware setup instructions cover Arduino Nano 33 IoT, MKR WiFi 1010, Uno, Nano, Raspberry Pi models, Raspberry Pi Pico, ESP8266, ESP32, and an optional particle sensor. Code example setup sections cover IoT cloud integration, graph web server, IFTTT, ESPHome for Home Assistant, Home Assistant POST, graph viewer s
