Temperature and Humidity logging: Arduino and ESP-01
We have problems with condensation in our house (UK weather). In order to evaluate the situation, I planned to log the day-to-day humidity and temperature. It seems to be a popular subject, with plenty of material online. The DHT-22 is a popular sensor, fairly cheap, 3.3V and 5V compatible, with a very simple wiring: Only need GND, VCC, DATA. It seems to have a broad support on almost all platforms.
