Raspberry PI and DHT22 Temperature and Humidity logger
“jjpfin” @ instructables.com build a Raspberry Pi based temperature and humidity datalogger using DHT22 sensor. Data is stored on mySQL server and can be viewed on browser.
This is an Raspberry Pi based temperature and humidity logger that uses 2 (works also with 1) Adafruit DHT22 sensors for measurements. You might have seen similar kind of instructions before, but this one has a twist. It doesn’t just read temperature and humidity from sensors, but it stores data to MySql database and provides means to read that temperature data with any web enabled device (computer, phone, tablet) web browser.
