WiFi Environmental Sensor
Temperature, humidity, CO2 with WiFi + MQTT
About this design
An indoor environmental monitor combining temperature, humidity, and CO₂ sensing over a WiFi link, running on AA batteries for six months. Built around an ESP32-C3 or similar, with I²C sensor bus and external antenna. Vectis selects every component, places it, routes the board, and ships a CE-ready certification package.
Typical applications
Smart-building HVAC control, indoor air-quality compliance for offices and schools, agricultural greenhouse monitoring, and home automation. Battery-powered sensors that can be deployed in minutes without a power run.
Compliance scope
Covers RED Directive (radio equipment), EN 300 328, EN 62311 (electromagnetic fields), EN 55032/35, and IEC 62368-1 for the battery enclosure. The full self-certification dossier is generated as part of the export bundle.
