Room temperature and humidity sensor using an Arduino
Arduino Room Sensor
A room temperature and humidity sensor, using an Arduino Nano 33 IoT and an Adafruit HTU21D-F Temperature & Humidity Sensor.
Total cost was 30€.
Collecting Data
The Arduino sends the sensor data to a Prometheus instance, hosted on a RPi 3.
The data can be displayed and analyzed using Grafana, which is also running on the RPi 3.
