This project is a temperature, humidity and barometric pressure sensor housed in a 3D printed case. It is designed to be placed in a protected place outside, and report sensor readings periodically over MQTT. It uses a small ESP32 for wifi communication, and requires a 5Vdc power source.

Features

Temperature/Humidity/Pressure sensor: BME280.
3D printed case is designed to allow airflow around the sensor.
Powered by 5V (standard USB power supplies will work)
Wifi connectivity, reports sensor readings to an MQTT broker.

Building this project will require:

3D printer to print the case components.
Basic soldering capability for the wiring.
A reasonably protected location to install the sensor that has access to 5V DC power.
