Introducing Climatron

Welcome to the home for Climatrons everywhere! We're happy you're interested in the Climatron Project. More information will be available here soon.

See you at Teardown 2026 in Portland, Oregon on July 24-26, 2026!

Climatron uses a Sensirion SEN-66 sensor to sample its surroundings, measuring temperature, humidity, carbon dioxide levels, airborne particulates, nitrous oxide, and volatile organic compounds. Current values as well as graphs of recent measurements are available through the built-in touchscreen color display, along with a five-day weather forecast for the current location. Overall indication of air quality for each environmental factor is provided through LEDs built into the unit's head, ranging from green for good through yellow, orange and red for fair, poor and bad respectively.

Data collected by Climatron can be published to ThingSpeak, InfluxDB, MQTT, and Home Assistant, allowing remote monitoring, review of history, and triggering of automations to control other devices such as a ventilation fan.
