Review on HiLetgo® Temperature Humidity 1 5V 3 6V Compatible by Johnny Pigao

HiLetgo has great sensors and this is one of them. This tiny module was extremely easy to plug in and get started. If you want a quick sketch example, there is an HTU21D library that will output humidity and temperature readings to the serial monitor every few seconds. Just search for "HTU21D" in the Arduino libraries collection. Considering the price and size of this nifty little module, it will likely be my go-to tool for measuring temperature and humidity from now on.
